Vorshlag 2011 Mustang 5.0 GT - track/autocross/street Project

[Fair]

Project Update for June 13, 2012: I am still recovering from last weekend's Optima Faceoff at HOT ROD Power Tour series of competition events. Wow, what a crazy two days! So much to talk about, the TV coverage was insane, and we did really well - considering all of the things that went wrong with the car and set-up. I have spent the last two days just cropping pictures and editing videos. I am still trying to wrap my head around the results (official results won't be out for "at least a week"), the car/set-up issues we ran into (all of which were my own damned fault), and the event itself.

More Event Prep

Let's back up and show some of the last minute prep work done before this event - a lot of little things piled up in the days before the Optima event. I figured there would be a lot on the line (and even more than I had bargained for!), so we wanted to get the car set-up, reliable, and ready. We did a pretty good job, but made some key mistakes - again, mostly from my tire selection and poor set-up choices.



The 295/35/18 Nitto NT-05 tires were mounted on the D-Force/Vorshlag 18x10" wheels, which were mounted on the car - and they looked great. To improve the front track width a bit for the track day, we went with 7mm spacers up front... it wasn't needed, but it "looked better" with them. I kinda knew there would be some TV coverage so vanity won out (and there was a LOT more TV crew than I had ever dreamed of). This 295 tire mounts on the 10" wheel beautifully and I wouldn't hesitate to recommend a 295mm tire for these D-Force wheels now. We've tried a 315mm race tire on these wheels and it was way too much, but this 295 fit great. The height was a little short but it was workable. This set of mounted and balanced wheels and tires is for sale! $1800 + shipping and they are yours ($2650 retail, mounted and balanced). Used for two days, still have tons of tread.



As you can see in the first pictures we also pulled off the big "93" numbers and "ESP/TTS" class letters from the side doors and front of the car, as Optima has their own decals and numbers for these events. Part of the repairs from the "windshield incident" required two new hood hinges, as we noticed when pulling the hood that both of them were torn to shreds (as seen above, right). We had the local Ford deliver those, painted them in red to match, and put the hood back on. Well, not before some PDR guy came by to look at the hood damage, who promptly man-handled the bent rear corners so badly that he cracked the paint. Never even tried to use the heat gun to get the paint warmed up. "uhhh... thanks?"



Since we had planned on running both the rear wing (track) and rear spoiler (autocross + speed-stop) at this weekend of events we did some tweaks to both rear aero packages. For the wing base plate mounts that bolt directly to the trunk structure, Ryan made some new lower "shims" (above left) that better match the curves and contours of the trunk, which turned out nicely. For the rear spoiler, two additional "struts" were added to the outer edges, which mounted forward to existing holes in the trunk (to some wing base plate mounting holes). These two front struts joined the existing 4 rear struts to make for a much more rigid structure. Now you can really push on the ends of the spoiler and it doesn't deflect.



Like we do before each track event or autocross (and for customers, now that Vorshlag is a NASA Approved HPDE tech shop), the car was given a good pre-track inspection. Ryan began by swapping over to the track pads (R4) and rotors and flushing the brakes with Motul RBF600 (which we now stock and sell). He noticed a bit of wear on all of the caliper and pad mounting hardware, which isn't a surprise considering how many times we've swapped rotors and pads (autocross set vs track set). The dust seals were FRIED and had burned to a crisp. So new caliper bolts, pad retaining pins, and dust seals were ordered. The dust seals had to come from Italy so those would have to wait, but the hardware was swapped along with the track set of rotors and pads before the event. These R4 track pads take a bit to get up to temp, so I had to be mindful of getting the brakes hot for the speed-stop and autocross events (this would bite me in the ass later).



An odd safety item we needed for this Optima event was a fire bottle "mounted in the car with a metal bracket". We called a fire extinguisher supplier and had two Halon bottles (one for Mustang, one for the E30) with roll bar mounts ordered over a week before the event. Of course these didn't arrive in time (and still haven't, two weeks later), so Ryan had to fab something up the morning of the event. It's a cheesy little 2.5 pound "BC" type bottle mounted to a metal bracket with a quick release (hitch pin), but it met the letter of the rules. The mount was plenty strong, but a little hinky looking - still better than some other set-ups we saw.



One car actually caught on fire at the track event as it was leaking transmission fluid onto exhaust all day, pouring smoke out while on track, and it finally was enough to burn. The track personnel couldn't get his fire bottle out quickly enough and they had to use one from the paddock. So there was a solid basis to this rule. We will chuck this 2.5 pound extinguisher (the bottle was on the harness bar upright) and mount the real 5 lb Halon bottle into the Mustang if/when it arrives.

Well this portion has already gotten long... I will start another update tomorrow.

Project Update for June 15, 2012: With all of the pre-event prep and changes made to the Mustang (see my last thread update, above) to tackle an autocross, speed-stop, and track event all in one weekend we loaded the car into the trailer Friday morning and headed to QuikTrip Park for the Friday events during the Optima Challenge Faceoff. We saw lots of cool hot rods and muscle cars on the highways, as the week long Power Tour was wrapping up at the same location... across the street in the parking lot for the at the horse track called Lone Star Park.

OPTIMA FACEOFF AT HOT ROD POWER TOUR

I was ready for autocrossing on the surface at LSP, as I had raced there many dozens of times and new how the site would bite. When we rolled up and saw what looked like thousands of cars parked all over the giant open asphalt lot at LSP, I was confused. I asked the guy at the gate: "Uhhhh... Where is the event!?!" "You see the small parking lot across the street? That's it." Oh damn. The lot used to park cars for the minor league baseball field (QuikTrip Park) and neighboring Verizon theater (which had some high school graduation going on) was our lot for the day. It was a much smaller, sealed asphalt surface, and I didn't know this site at all.



Oh well, no home court advantage today (but I knew the ECR track better than any other track I've raced on - hopefully that would pay off tomorrow!). We wound our way through the barricades and finally found a spot to park the truck and trailer. While Amy unloaded the Mustang I went over to registration, which was already well underway. The organizers had several huge trailers set-up, including this massive multi-level rig Optima brought they called Optima Prime. It really was like some massive Transformer, with all of these swiveled and rotated and flipped out sections on this 53' trailer, and both air conditioned space and a shaded upper level observation deck. Very cool.

K&N, Bowler Transmissions/Royal Purple, RideTech, Wilwood, and others also had their big display trailers set-up, there were bleachers for spectators to sit in, (hundreds of people came by to watch the events) and TV cameras EVERYWHERE - on man lifts/cranes, crews walking around with 2 SpeedTV hosts, mobile lipstick cameras they put in and on cars, and more. I was blown away by all of this pageantry and spectacle for an autocross - in 24 years of competing in this sport I had NEVER seen anything like it! After I shook my head, pinched myself and was positive this was real, I made it up to the registration platform inside the Optima trailer. I got checked in, signed all sorts of insurance and release forms (TV stuff), they handed me an event T-shirt + a gaggle of decals, and I went back and got the car "stickered up" and ready.



Amy did her magic and put the huge Optima side decal boards, Optima numbers, and Optima windshield banner decals on perfectly (as usual we laid them up wet - you shoulda seen some of the other decal installations!) Drove the Mustang over to the pre-grid area where all of the entrants were lining up and started talking to some folks. Damn fine cars here, including the LG ZR1 and numerous magazine featured cars I had seen before or knew of. Wow, there was some serious hardware in the 40 car field! After snapping some pics of several of my dream cars, I began to walk the tight autocross course several times, and also talking to some friends I knew that were entered. There was a driver's meeting at the Optima Prime trailer, then we were split into 2 groups, and my group was lined up for the Speed Stop Event.

Wilwood Disc Brakes Speed-Stop Event



Now remember: we had just mounted these brand new Nitto tires, rolled the car onto and out of the trailer, and then driven it 100 feet to the grid area. So yea, the tires were covered in silicone mold release. Also, the R4 brake pads and dedicated rotors were swapped on, but not in the perfect order from the last time they were used, also with zero driving. Guess where I'm going here? The tires were not scrubbed in and the brakes were not bedded, so I had NO grip and NO brakes on my first 3 speed stop attempts! Blew right out of the stop box every time.

This also wasn't a straight forward "accelerate then brake" deal, due to the size of the lot. We had a decent little acceleration zone (I saw a peak of ~60 mph), then a pirouette cone lined in water barriers, then a super tight offset slalom (35' apart with significant offsets) into the 20x40' stop box. And there was water seeping up through the parking lot at the front of the stop box, which never stopped all day (from heavy rains the day before). Not complaining - we all had to drive the same thing - it just wasn't a straight "go and stop" kind of deal. You had to set-up for the turn-around and subsequent slalom to get a good time. The acceleration box from the standing start was also pretty bad until it rubbered-in, later in the day.


Lined up for the Start-Stop event in front of another crowd of spectators

Right before the Speed Stop event was to start they had pushed our group temporarily over into the autocross line for 1 run (while some cars were moved in the Speed-Stop area), which also felt like driving on greased ice. My first 3 Speed-Stop runs were pathetic, and I blew through the stop box each time, pressing like mad on the brake pedal. After those first 4 attempts to do anything was losing my mind. I noticed I had no fuel left, and I was drenched in sweat already - and had no water or ice in our cooler, and it was already hot (95°F day). I had to get out of here and get fuel, water, ice, scrub the tires and bed the brakes. I asked for a fuel break, was told where to exit, and I got out of that parking lot. About 1 mile away was a RaceTrac gas station, and in that mile of driving I broke more traffic laws than I can count. It must of looked like somebody was driving a car full of sting-crazy bees - I was swerving across three lanes, accelerating like mad, then panic stopping. But when I got back 10 minutes later the brakes were bedded and those tires were scrubbed in.

Ride-Tech Street Challenge Autocross



So with the silicone off the tires the the brake pad surfaces matching the rotors, I went back in line to wait for my group to start the autocross portion for the next hour. We had 4 straight hours of racing (with one 15 minute break where we went back to pre-grid), and each hour we'd rotate from S-S to Auto-x. My first auto-x run on the greased-up tires was a 35.6 sec run. My next run an hour later on the now-scrubbed tires was a 33.2. Then I had a string of 32s, then five runs in the 31s. I was getting faster and the announcer noticed...



By the end of the day I had taken about 12 autocross runs and managed to run a 30.8 and a 30.5 second pass. We thought those might be in the top three but since they were not posting times we didn't know how close we were. The announcer was calling out times over the speakers, but these were pointed away from the grid and towards the crowd. By around 4 pm I had two buddies join us (McCall and Ed, the two nose-pickers shown below) that were helping with tire pressures, tire spraying (these NT-05s were boiling in short order), keeping me hydrated, and this let Amy go across the event site to the Optima trailer and listen for our times (which she would text to us after each run).



With 40 cars moving through the line it made for a little wait between each run, and the camera crew used those periods to do on-camera interviews with drivers. I was interviewed 3 times during autocross & Speed-Stop events, and you can hear one of the interviews at the end of my autocross video, below.

continued from above

Even though this was a super tight autocross (where I was at steering lock 6 times per run) and there were smaller cars there that could navigate the course better than this wide Mustang (EVO, three MR2s, etc), somehow we did all right and our little Mustang ended up with the fastest time at the end of the day! Whew... Of course we didn't know this until the end of Saturday, because they kept the results final secret - hey, it was part of the drama of TV, so I get it. The look on my face when they announced me as the autocross winner must have been pretty funny... because I was totally shocked!



Click for in-car video of my Speed Stop Run #7, 14.4 seconds

Unfortunately I never made a good showing at the Speed-Stop event all day. My run in the video above was my best on that course and it was a solid 0.9 second off the Todd Earlsey's Evo, who placed first in the event (and 2nd in the autocross - he had lots of good points already racked up going into day 2). They only announced the top 3 finishers after the Saturday awards ceremony so I didn't know where exactly I ended up, but now that the final results are up it looks like I ended up way down in 9th (this placing utterly killed my chance at the overall win). I took about 8 runs over 2 hours on that S-S course and never really got a good stop or turn-around in, with a massive front end push in the turn-around and the brakes just not working.

The start box rubbered-in after a number of entrants made big smoky burn-outs and I could finally leave the line on these street tires at about 1800 rpm late in the day, but that was the only improvement I saw. The pedal was hard as a brick at the braking zone into the pirouette cone, and just as bad into the stop box. I had no power assist with the brakes; I was jamming that pedal down with all my strength with very little affect. We tried to diagnose the booster and vacuum lines on site but could not find a vacuum leak big enough to leak down the booster - it just didn't have any pedal assist after any high RPM sprint. Something was broken. We also had a major push that we couldn't dial out, even with a crazy alignment, tire pressure tweaks, and radical shock changes.

Roshambo?! (Autocross Shoot-out)

At the end of the day we had a special non-points event in store. By now it was 6:30 pm and time for the "autocross shoot-out", with the top 16 drivers doing a head-to-head "race to the line" sort of deal. They called it Roshambo, but many of you would know it as a "double-cross". They called the top 16 drivers' names, where I was the last one to be called, and they pulled me to the front of the line (didn't know at the time, but this was because I had won the autocross). When they described the event at the driver's meeting they were wrapping up extending the course between the formerly separate finish to the start lines, with a short and TIGHT section of course. I listened to the driver's meeting instructions... as I walked this new section of course 30 yards away. Three times. Nobody else that I could see walked it, and therefore didn't know how tight it was.


Left: Lined up with eventual Roshambo winner Brian Finsh. Right: Lots of sparks from the rear brakes (see more here)

This extra course knowledge paid off in my first round heads-up match, as I blazed through this newly added section of course to make the continuous lap and I won my first round by over a second. One thing that was unique was that any driver that hit a cone was eliminated - and if both drivers hit a cone they were BOTH out. So during the first round's 8 match-ups there were some cones, and a pair of drivers who both hit cones. That pair that coned out made for a "bye" run for me in round 2 - but I still had to make a clean cone-free run. It was a slow parade lap, of course. In the 3rd round I was lined up against the 1971 Camaro of Brian Finch. Now he had an unusual advantage - not only is he a series regular (and a great driver!) but he entered 2 cars in the event, and both cars were fast enough to get into Roshambo... so he had twice as many looks at the new course by the 3rd round (his 1970 Nova had been bumped out in his 1970 Camaro). When we ran heads up I got behind in the slalom and lost a lot of time, and was not surprised when he beat me back to the line. He ended up going onto the 4th and final round against Louis Gigliotti, and Brian won the Roshambo shootout. Didn't count for much more than bragging rights, but its a cool event - especially since there was only one class of cars racing.

End of Autocross Day

So after all of that I had to look back and ponder... this really was an AMAZING day of autocrossing. I can honestly say I have never seen anything remotely like this. Cheering crowds of spectators, pumped up announcers, and TV cameras everywhere. At an autocross. Insane!

So by now its closing in on 8 pm and we still had some work to do. Hot, tired, sweaty, and tired. I went to try to find out if there were any printed results for the autocross, but they weren't telling so I had to stew all night after the Roshambo loss, not knowing how I did in the timed event. With Ed and McCall's help we swapped the spoiler for the wing to use on the drive over to ECR in the morning and at the track, and also to show some more parts we had designed and built. Loaded the car into the trailer and drove to Costas' to crash out for the night, after grabbing some dinner at Fuzzy's Taco, then watched some F1 practice. Long, hot, exhausting day - and we had another hot long day lined up for Saturday.

Project Update for June 19, 2012 - Part 1 of 3?! Finally getting to the write-up covering Track portion of the Optima Faceoff event. This has become embarrassingly long. These write-ups take more time than you might imagine, and sometimes it grows beyond my expectations. There was a lot going on this weekend!

When we left off above, the Friday Autocross, Roshambo, and Speed Stop events were wrapped up and we had loaded up and towed the rig to a nearby friend's house to crash for the night. We were supposed to meet back at the same parking lot at QT Park at 6:30 am the next morning for the drive over to ECR...

Detroit Speed Road Rally

The deal was they wanted everyone (that could) to drive from the QT Park area to ECR, which was a 70+ mile drive. This was to show entrants that were real "street cars", and successfully making this trip gained you 5 points in the competition. With the three main events worth up to 25 points each, and the one other "Design" competition worth another 5, every point mattered (we didn't learn the final point tallies or event break-down until a week after the event). And if there was ever a car that was easily capable of street driving, it was our emissions legal, stock-motored, daily driven Mustang GT.



We rolled up to the Lone Star Park parking lot at 6:30 am to unload the trailer, but Optima Jim was quickly turning everyone around. Apparently there was a scheduling mix-up on the parking lots we were supposed to meet at? Jim was pointing the HOT ROD Power Tour Long Haul guys to one spot for their scheduled group picture and telling the Optima Faceoff drivers to meet at a nearby auto parts store parking lot for the group drive to ECR. We went to the same RaceTrac gas station that I had fueled up the day before, unloaded the Mustang, then drove it next door to the gathering spot for the group drive to the road race track for the day's events.

Two other Dallas locals and I talked about the route from this parking lot in south Arlington up to ECR and came up with a perfect route - simple, fewest turns, no toll roads, and bypassed the interstate running right next to Texas Motor Speedway, which had an Indycar race scheduled that day (epic traffic!). We talked to the lead car driver Optima Jim, he liked the idea, so one of the locals in a C6 (Robert Wilson) led the entire group and I brought up the rear to catch any stragglers. The hour and a half long drive went off without incident, the group stayed together, nobody got lost, and the camera car was busy the whole time filming the 40+ cars. This group of stickered up muscle cars was quite a sight driving through Dallas that day, I assure you!

Eagles Canyon Raceway - BFGoodrich Hot Lap Challenge

This was the main event of the weekend and the one I was most worried about. Once we arrived at ECR I found that Amy, who had left 15 minutes before us, had already arrived and set-up our truck/trailer in the perfect spot: right next to the track in the paddock area. We quickly set-up the new roll-out shade, which then became a popular spot for many competitors to hide from the sun throughout the day. I had the front toe set at 5/16" total out for the autocross, to help this pig to turn, so I reset the toe at the track to 1/8" total out (which is what we normally run for track use). We reset the tire pressures to 35F, 30R, bumped up the compression and rebound a bit on the Motons, and re-checked camber (-4° up front). The oil was topped off and everything was checked; after the first session the front tires had gotten up to 47 psi, so we lowered them to 37F/32R hot.


Left: Vorshlag trailer was an oasis of shade. Right: Picture of the Mustang from the ECR clubhouse deck

There was a driver's meeting at 9 am and one of the race organizers approached me about talking about the track, after they went over flags and passing rules. There were six of us in attendance that had driven ECR before, but somebody told them that I had more laps here than the others. I guess... maybe I did? I ran TTU in the first NASA event at ECR in 2008 (setting the fastest TT time and a TTU record in the E36 Alpha car, which has long since been smashed), had run two LeMons endurance races there in 2011, and dozens of other events over the past 5 years at this 2.5 mile road course. So I got up there and spoke to the racers for 10 minutes about the layout, the various turns, pit in/out, runoff areas, places that can get you, where corner stations were, etc. Basically: ECR is a great track with a bunch of tight turns joined by a variety of 1000-2000' straights, and the fun feature of 70' elevation changes in some areas. It's hard on brakes, bumpy in areas (good shocks help), horsepower pays off on the straights, but there is no high speed cornering and you rarely see cars exceed 125 mph. I talked about lap times as well: 2:15 is what Spec Miata runs, and a 2:00 flat is FAST for street tires and R compounds alike (AI record is 2 flat).

After the driver's meeting I ended up talking to a dozen more folks about tires, the course, and the surface. People came by the trailer all day to discuss set-ups and I was glad to help. Our car was far from the ringer that day, as there was some SERIOUS hardware that I knew would be fast, and a few of the locals were worth watching out for: Louize Gigliotti in the LG-prepped ZR1 and Todd Earlsey in the Evo Dynamics prepared EVO were two. Todd regularly runs in NASA TT and Louis sees all sorts of track events in crazy cars all the time. I talked a bit with Dave Michaels, who was driving the Lingenfelter (LPE) prepared 5th gen Camaro, which sounded pretty gnarly as well. There were several 500-800 whp cars in attendance that could be spoilers, but I was hoping that ECR track experience would pay more dividends than brute horsepower.

Well, it turns out that having both didn't hurt! The ZR1 had me worried because of his experience, skill, the fact that it started out as a $120K ZR1, the 345 Michelins I noticed it was riding on, and the fact that LG had prepped the heck out of this one (this is Lou's personal car). LGMotorsports knows Corvettes and this was no run-of-the mill ZR1, having a fully built motor, ported blower, custom splitter and wing, track-worthy suspension, carbon ceramic brakes, and lots of other modifications they have made to it for hill climb competitions (it recently dyno'd at 755 whp and 820 wtq). So yeah, our daily driven Mustang GT with a stock engine and some bolt-ons was a bit out-gunned on the horsepower front. I felt like our Mustang wasn't probably going to hang with these crazy muscle cars, 600 whp GTRs, Lambos, ZL1 Camaro, C6 Corvettes and ZR1s if they were driven halfway well.

I was also a little iffy about my tire choice, as the Nitto NT-05s were prone to overheating in the little 30 second autocross runs the day before. How would these handle track sessions in Texas summer heat? The answer is... they didn't. I will go ahead and say something that a few HPDE gurus won't agree with: Nitto NT-05s suck. These tires are greatly inferior to Yokohama AD08s, Bridgestone RE-11s, Hankook RS3, and Dunlop Star Specs that I've tracked and/or autocrossed with on this same car. The problem is - all of those other tires are under 200 treadwear, except the Dunlop, which has a maximum size of 275/35/18. I wanted more tire for this car, because when I ran ECR in December 2011 in the Mustang (with quicker lap times) on 275/40/18 Bridgestone RE-11s it was very "rear traction limited". My hope was that these wider 295/35/18 Nitto NT-05s would better take the heat and abuse that the Mustang would dish out. Bad call on my part.

After making a few slow parade laps behind a pace car I came in and waited in grid for the first real timed session of the day. This was about 10:30 am, which ended up being the coolest session of the day (where fastest laps were turned by many). After being told by the race director and camera crews to move to the front of the line, I ended up being the first car out (with I think Luis' ZR1, the LPE Camaro, and the Todd's EVO behind me). I mistakenly thought (from reading the Optima event regs) that we would only get 2 sessions all day and that each hot lap (3 laps per) would count cumulatively (like at a One Lap of America event). They had said that any off could DSQ you for the session, too (also sort of like OLOA). So this meant I had to make every lap count, right out of the box, and have zero mistakes. When every lap counts you drive differently, and I hoped my prior ECR experience and aggressive driving would pay off.

So... the posted event regulations weren't actually how they ended up running the track portion. Instead it was all about getting one golden lap for the day, like any normal NASA Time Trial. That makes a lot more sense, and we finally confirmed this "just try to get one good lap" strategy by the 3rd session on track. Live and learn, and never trust the pre-published event regs (because to this point, few of them applied to this actual event). After seeing how much this series had grown in 2012, and how this was the first "big TV show" versions of the Optima Qualifier events, it wasn't a surprise that they would be tweaking the format as the weekend progressed. Its all good.


Click for in-car video from my first of seven on-track sessions of the day - and my slowest

So the in-car video from my first session is shown above. They lined me up first, with a group of 3 or 4 cars, with a scheduled 3 hot laps. They wanted to figure out spacing, camera panning, etc - eventually they had groups of 5 to 8 cars on track at once. I never saw anyone else in the first heat (except the EVO parked on an access road, after it blew off an inlet hose). I have to admit that it was a bit nerve racking having 2 bullet cameras added to your car (one pointing at me, one exterior) in addition to my own in-car video set-up, plus half a dozen manned and elevated camera stations around the track. The TV crew told us at the beginning of the day that they were trying to space us far enough apart on track so that each camera station could follow each car through the corners separately, for nearly 100% on-track video coverage for each driver. These camera stations were hard to miss, too - it was WEIRD having guys way up on cranes with mounted SpeedTV cameras tracking you through a corner around Eagles Canyon. I've never been filmed from multiple TV cameras like this and it made me a bit nervous at the beginning of the day.


While many cars had problems, our little Mustang kept pounding out lap after lap

more below...

continued from above

So how was the Mustang on the NT-05s? It was terrible, the tires overheated quickly, and they made a LOT of noise. I was told by many folks they could hear me from a mile away, just due to the howling of the tires. In my first session where I went 10/10ths on every lap I only managed a best of 2:05.9. I could get a half of a lap of hard driving before the rears would start to boil and I had to back-pedal coming out of 3rd gear corners. I had to watch out for overheating on my out lap. 2nd gear was completely unusable on the exit of Turn 11, so I left it in 3rd and skated around delicately. The car had a MASSIVE push all day (even after lots of set-up changes), especially after the right front got hot, so the car would just push push PUSH worse if I didn't take a cool-down lap.

The same steering feedback shudder we've been fighting for a year was still present (new steering racks are still on national backorder until the end of June), and the brakes sucked. It took me the first two track sessions before I figured out that the booster just wasn't working at speed, and I had to brute force the brake pedal to get it to stop. It made heel-toe downshifts tricky, and I did a lot of left foot braking to be able to press hard enough (and would swap feet mid-braking zone). By my 3rd session I could finally get into threshold braking on all corners. After I figured out the work-around for the busted brake booster, and once I finally listened to JasonM, Ed, Mike and Amy (thanks for coming out to help guys! It was huge) about taking one hot lap followed by one cool down lap, I started dropping time. 2:04s were followed by a lone 2:03.9. Here are some abbreviated results, but all are linked here.



Name..........Fastest Time.. (Car)
Louis Gigliotti.........1:59.772 (LG ZR1)
Dave Michaels.....2:01.904 (LPE 5th gen Camaro)
Terry Fair...............2:03.967 (Vorshlag S197 Mustang)
Todd Earlsey........2:05.756 (Evo-D EVO-9)
Brian Finch...........2:06.052 (Royal Purple 71 Camaro)

So my 2:03.9 lap ended up being the 3rd fastest time overall, which was a bit of a surprise. That is slower than I've run in the same car on narrower tires here before, but it was the best I could muster that day. Maybe it was the conditions, the heat, the NT-05s, and a bunch of broken parts (steering rack + booster), but I still wasn't happy with the laps in the Mustang. I also regretted the 550 #/in front 275#/in rear springs, which have done nothing but make the car push since we put them on (when we added the Moton Club Sports). Those have since come off and we've gone back with the previous set-up of 450F/175R. It always rotated better, put power down better, and didn't have this awful push. (I'll retest this set-up this weekend at ECR).



During the last few later afternoon sessions the heat was rising and the times were too - nobody was going fast. I knew I wasn't going to find much if any more time and the rear tires were cooked. I had been talking to Ed during my sessions, who was relaying to me the announced times lap by lap. The Ford "Sync" system linked to my iPhone via Bluetooth works VERY well, and we had some of the best 2-way on track comms I've ever seen at ECR. Ed would call me before I went out on course, I'd answer, and just cranked up the radio speakers. With a full face helmet he could hear me talking back to him, too. He spotted traffic for me, told me lap times, and most importantly - calmed me down when I was over-driving the car. That's when we managed the 2:03 lap time - with a strategy of cool down laps then hot laps.



They allowed competitors to run on track almost as often as they liked, and each time they announced "we have an empty grid" I would scramble up there, if I wasn't already in line. So after six track sessions (?!) I was pretty burned out and had spent very little time out of the car and out of my driver's suit. The crew that was there was keeping me hydrated between sessions, and the camera guys were constantly adding and removing cameras to the car between sessions. The handful of minutes I stepped out of the car I was peeling off the driving suit and damn near passed out in our trailer - out of the sun. I still ended up doing another 3 or 4 on-camera interviews, as the crew figured out that I was running top 3 times, and since we did well enough in the autocross to possibly be an "overall" contender. Goldberg was super nice and really liked the car, and kept encouraging us to keep pushing it out on track. So I kept going out, over and over, pouring more and more fuel into the tank.



I inadvertently left my Sony HD video camera on after my 2nd track session (stupid!) and killed both the battery and filled up the SD card after, so I didn't get much in-car video of my own. This week I purchased a mega-over-sized battery and two more SD cards, plus a wired remote from Sony so I can control and see when the damn thing is recording.

continued from above

My last two sessions the lap times simply weren't there. Ran some 2:04s, lots of 2:05s, but it was just too damned hot. There was a camera crew by the pit wall and a crowd was gathering, including the TV host Goldberg... and with the rear tires overheated, I started hooning. A lot. They were loving it, waving for more, so I kept stepping the tail out in turn 11... and then into 3, and 7, and basically in front of each big camera station on course. I was hooning my ass off - cameras make me stupid. I also had Ed on the phone telling me that the announcer and the crowd were eating it up, and they were betting how much I'd hang it out each lap, so I gave them more and more, and started kicking the car all the way through 11 sideways.



Now I still don't condone the "sport" of drifting, but if "driving a little loose" gets me on TV, I'm gonna do it. It's not hard - we used to mess around after autocrosses back in college (TAMSCC!) and set-up these impromptu drift sessions. This was long before the Drifting "sport" became a fad, before the e-brakes and the banged up cars, and decades before Ken Block and funny shoes. We were just a bunch of autocrossers "practicing". So if this event makes it into a TV show some of this clowning might get shown. The camera guys kept telling me "this is great stuff!", and the car wasn't getting any faster, so who knows?

Lingenfelter Performance and Design Challenge

One more "competition" for the weekend was a "performance and design" subjective thing. Again, I thought this was for a full 25 points, but it ended up only being a 5 point deal so it didn't alter the results too much. Compared to the crazy hardware that is typical at these events, our car is pretty plain and I figured we'd do poorly in this part of the challenge.


Left: The winner of the Design Challenge, Rodney Moore. Right: The Design Challenge judges talking to me about the Mustang (it got 5th place)

The top guys from Lingenfelter, Optima and Wilwood came by and checked out the car and asked several questions. The point of this judgement was visual improvements, of which we have done very little. I told them, hey, this is our suspension test mule so it's not about looks... but we've made this rear wing set-up, the rear spoiler used on Friday, added this LS splitter, these "Vorshlag" wheels are ours, and most importantly these are our camber plates and other suspension bits. I guess it helped and the Mustang scored the last point in 5th position.

Top Ten Track Shoot-out

This was another non-points event they held, run after the day's "BFG Hot Lap Challenge" track time was done. The ten fastest cars were called up to the grid, lined from fastest to slowest, and they wanted us to make a 5 lap sprint to the checkered flag. The announcer said it was all about getting to the flag first, and I tried to ask someone on pit road if this was indeed the case. Ed was talking to me on the phone during the whole session again, and passing along lap times, announcer's and crowd's feedback, etc. As far as we knew it was about working your way up through the pack and getting to the finish line first. They lined up Lewis' ZR1 in front, then the LPE Camaro was supposed to be 2nd (but it caught on fire late in the day, then was pouring transmission fluid onto the exhaust by now and wasn't allowed to run) so they moved me up from 3rd place. The rest of the field was behind me, but all I had eyes for was the ZR1 Corvette. They sent us out 15 seconds apart, and we were supposed to NOT pass on the out lap (yellow flag out lap were the rules for the day), but after the green flag dropped it was on.

I tore ass through pit-out and was catching the ZR1 by turn 3. I knew how each of the top 10 cars were performing from running so many sessions that day - everyone was running hot, taking cool down laps, or only making 1-2 lap sessions. I felt like I could push the Mustang 10/10ths on a 5 lap sprint without slowing down more than a second from my fastest time all day. Driving Flat Out for each lap wouldn't make for the fastest peak time, but it could allow me to pass faster cars. And the only one faster left was the ZR1. So on the out lap I hauled ass, caught up to Loise's Corvette, and painted his mirrors red with Mustang. I wasn't going to pass him on the warm up lap, but I was letting him know I was back here. "Hi, Louis!" He saw me swerving back and forth, as I was baiting him to push it hard on the out lap. That boosted ZR1 had about 1 fast lap in it, but the Mustang could lay down 5 heaters...

He fell for it by turn 5, put the hammer down, and we were in a sprint race on the out lap! Come on, heat soak that intercooler! By the time we were at the green flag I think there was 8 or so car lengths between us and he was hanging it out trying to gap me. I pushed as hard as I could on the first timed lap and ran a 2:04 to Lewiz's 2:00. On lap 2 the ZR1 was cooking, the intercooler was heat-soaked, and I got a hasty point by into turn 3, which I took with a smile! Ed was hooting and hollering, saying that the announcer and the crowd was going nuts! "Pass him! Pass him!" I got around the ZR1 and opened up a huge gap. The ZR1 slowed to a 2:38 on lap two. Now that I was in the lead I drove like a man possessed, pushing to the limit, and the tires quickly overheated.


Left: the field got bunched up like this after a couple of laps, a good half lap behind me. Right: Pulling in first felt good!

I didn't care - these tires sucked and I'd NEVER be driving on them again, so I was eager to sacrifice the set. Ed told me that my gap was big and nobody was catching up, the crowd was going nuts, so I started pushing too hard... and hooning a little. Then started hooning a LOT. The crowd on pit wall was waving and shooting video, and I think I was waving back while going sideways. By the 5th and final lap I had a big gap on the field and was catching the last car, and still yawing through any turn that had a camera. I took the checker, then a much needed cool-down lap. Damn, I wish my camera was working during that session... that was THE most fun I've had behind the wheel in my life. Pushing the car, passing the ZR1, hooning for the crowds and cameras, and Ed egging me on via bluetooth. That was a smile that took hours to wear off!


Goldberg giving me the thumbs up after I made it to the checkered flag first. Parc ferme, P1!

I pulled into pit road and Goldberg was telling the TV crew, "I want Terry's Mustang RIGHT HERE, in front!" (Amy was standing next to him). I pulled up to where they wanted me, climbed out, and was drenched in sweat. I thought I had won the "top ten shootout", but they decided to award the win to the fastest lap driven, which was the ZR1. Again, by now we were all used to the "fluid nature" of the event structure (there was some interesting radio chatter, arguing one way or the other, even after the checkered flag was thrown). Fair enough. The camera crew went to interview sponsors, the LG crew, and others. Of all of the events during the weekend, this was where I felt I did the best. I knew who got through 5 laps fastest and had a huge blast doing it.


Left: LG crew being interviewed after winning the top ten shootout. Right: Me, Lou, and Louis talking after the top ten laps.

After we were done with the cameras, Loueis made a crack about the out lap "All I could see in my mirrors was red, you ass!" We all had a good laugh waiting for the cars to cool down and the final camera work to wrap up. I've known the guys at LG for over a decade and Louis is a friend of mine, so all of my wise cracks (like misspelling his name!) are in good humor. They brought one damned fast car to this event and clearly had the fastest lap time all day, and in the top ten shootout, and I begrudge them nothing. I've owned and raced multiple Corvettes myself and wish dearly that I could own one (I don't race Corvettes for business reasons, but that is all), especially a ZR1 as badass as theirs!

Overall Placement

Once that little pit row gathering ended, I took the car back to the trailer and peeled out of my driving suit, then started guzzling water (Amy and I were laid up all day Sunday with the after-effects of dehydration). The guys took care of the car and got everything shut down. Our whole crew piled into a truck and drove up the hill to the awards presentation at Optima Prime.It was 6pm on Saturday and we still had no idea how our car had placed. I still had no clue that we had won the autocross, nor did I know I placed so poorly in the Speed Stop. I knew fairly well that we were 3rd fastest in the track portion, but that was the only thing concrete. The big questions was: who was the overall winner, and who would get the invite(s) to the BIG Optima Shootout in November? (held right after the SEMA show)

[Fair]

continued from above

That once-a-year street car shootout has been televised on Speed for a while and that was the goal: get an invite. They had warned us that the invitees were more about the "spirit of the event" and not necessarily the fastest cars, but we held out hope.



Left: one of my on-camera interviews with Goldberg, "I don't know what to do with my hands..." Right: After the Top Ten Shootout

They rattled off the top 3 finishers in each category, with the Speed Stop winner (Todd's EVO), Track day winner (Louis' ZR1), the design competition winner (Rodney Moore's beautiful 1970 440-six pack Cuda), then they rattled off the autocross winners... I wasn't third, I wasn't second, then they rattled off "with a time of 30.5".. hey, didn't I run that time? "Terry Fair". Whu.. hey, that is me?! I was completely FLOORED, as I thought all along I had done no better than 3rd place in the cone carving. On stage they asked me, "How did you get through that tight course so fast?" I said something like "I tried to make the car as narrow as I could!" Did I mention that cameras make me stupid? I probably looked like Ricky Bobby in this clip for every TV interview I did. "I felt like I was in a space ship..."



After they did the complicated math for the 5 scored categories, the overall placings were: Todd's EVO in first, L3w1z' ZR1 in second, and my Mustang + Brian Finch's Camaro tied for third. The two invitees to the "big show" in November ended up being two excited entrants with interesting stories (both of whom did the "Long Haul" for HOT ROD's Power Tour) that weren't too terribly close to the top of the time sheets in any given event. Again, "spirit of the event" and all. Heck, after finding out that I placed 1st in the autocross and 3rd overall I was so relieved that I didn't care about not getting an Optima Ultimate Street Car Shootout invitation. Not much, anyway.


The Optima Qualifier Events - Should You Enter?

It's hard to describe how insanely fun and different this event was. The same mega-trailers that were at QuikTrip Park were relocated to the top of the hill at ECR in the early hours of the morning, again - I had never seen an autocross or track event of this magnitude, with this level of sponsorship support and camera coverage, especially at our little club track! The various crews of Optima series folks outdid themselves on Saturday with big man lifts and cranes out on course with manned TV cameras covering 90% of the 2.5 mile road course. They had AMB transponders; portable lipstick cameras on several cars in each session; multiple radio channels for TV crew, race control and corner workers; and the SCCA corner workers did an excellent job flagging, as usual. Lunch was delicious catered Bar-B-Q, free to all entrants, and the TV hosts + Optima folks + race control crew were all super friendly and professional all weekend.


Left: Our crew getting the car ready between sessions. Right: The plague of grasshoppers did a number on the cars!

This Optima series is run like nothing I have ever seen in the SCCA, NASA, or any HPDE group. Even pro level road racing series don't have crews that work like this. Amazing, slick, punctual, professional and well worth every penny of my meager entry fee. I got so much track time, tons of autocross and speed stop runs, a cool T-shirt, free food, an unforgettable experience, and we might even see the little red Mustang on TV if we're lucky. Not bad for 230 bucks! After reading this, if you thought this sounds like fun, and you have an Optima Qualifier event near you - by all means, do it! Sure, running on 200 treadwear street tires can be a buzz kill, but everyone is on the same type of tires (here's a hint: use the Michelin PSS!). Yes, there are some tuner shops' crazy cars and a few semi-professional drivers that are regulars in the series - but as you can see, three local NASA regulars did pretty well in the overall results at this one.

Just be prepared for a little more emphasis on the TV show aspects than the straight forward competition events you may be used to, but it was still very competitive. Not knowing the standings from each event in real time was frustrating, but all part of the show! Go in with the right mind-set and you will have a blast. And who knows - you just might end up on TV (they will be filming at several Optima Qualifiers and making a series of shows leading up to the November shootout; I'll post up when we know when/if this event's show goes to air).

What's Next?

Man, its been a week and a half since this event and I'm still smarting from the poor placings in the Speed Stop and Track portions. I will look back, remember all of the things wrong with the car, and just shake my head. There was nothing we can do about the steering rack for the past few months (short of pulling one from a wrecked 2011+ car), but the brake booster issues, crappy tires, spring rate/set-up problems, and unscrubbed tires and brake pads were all bone-head mistakes that could have been avoided. I didn't take this event serious enough to do any testing on the NT-05s, where we could have made some adjustments. Knowing how much TV coverage this event got I wish I could go back and do some things differently. Hindsight is 20:20...

It's hard to follow that crazy event with a lowly track day or autocross, but that's what we've got planned. Luckily we had two weeks and a weekend off of any sort of racing, to recover. Ryan has already rebuilt the Mustang's front calipers (dust seals, hardware, new brake line, new fluid, etc), swapped out to the softer springs, and fixed a number of little things that plagued the Mustang over the Optima weekend - I'll cover this in my next thread update. The Mustang has a few more track events to attend this year before we move it to a more dedicated ESP-autocross-only preparation plan for the remainder of 2012. We're taking it back to ECR again for an HPDE "fun track day" Saturday, June 23rd. For details on how to sign up, click here ($150, unstructured track day - join us!). We'll run the 315 Kumho V710s, the "old" (softer) spring set-up on the Motons, and I will play with rear aero Angle Of Attack (AOA) at this event (we started to tweak this at the end of the Optima event).



Hopefully with these fixes and real R compounds the Mustang can crack the 2 minute mark (I ran 1:57s back in 2008 with a junkyard 5.7L in the E36, having zero track experience at ECR). The American Iron track record is 2:00 flat, so beating that is the goal. Amy is bringing our E46 330 "TTD" car (shown above) for some laps on fresh 285/30/18 Hoosier R6s to try to outrun our existing TTD track record, which was a 2:12.9 (set by Paul Costas in our BMW 330, 2 years ago, on crapped-out Yokohamas). This car has been getting worked on lately, and is now streetable again (new high flow cat). Sunday I will swap out the rear wing for the spoiler and Amy and I will run the Mustang at an SCCA autocross at Texas Motor Speedway, testing the spring set-up changes on a known site and the known-good Kumhos. After that we have a 2 week break we will try to use to design and build some new rear suspension bits.



We've also started to finally attack another in-house project car, specifically with the goal to be able to enter these "wide open" street car type track events, like the Optima Challenge, TX2K, OLOA, UTCC, and more. This is using our white E46 BMW 330Ci chassis, a big nasty LS motor, with goals of light weight, lots of tire, and some custom aero. Check our BMW E46 330 LS1 "Alpha" build thread soon for more details. We couldn't ever really find a good racing class to build this E46 LS1 swap mule for - everything we came up with had some goofy limitation or classing restriction. Building the E46 Alpha for these unlimited street car events let's us show some more of our race prep services, tests our production E46 LSx swap parts, and yet keeping it streetable (working windows, wipers, lights, defrost, ABS) helps us relate to more of our customer's needs. It also lets us enter a variety of street car competition events with it. We've begun tearing into this car this week for a full-on "track terror / still streetable / no rules" build. Because if I do another Optima event, I'm not going to take a knife to a gun fight again!

Cheers,
