First race I loaded to 2k and picked it off the line.

After that it was 1500 or so rolling out under moderate throttle. Still getting wheel hop and spinning in 2nd gear pedal to the floor.

If we were actually allowed to run in the prepped grooves, would've been a different story.

those grooves are for people with drag radials or slicks. they were letting some cars with bigs and lils use the groove. they dont want street tires ruining the grooves.

They kicked Ant off the grooves when he bolted up his DRs, he even told them he swapped his wheels/tires out .. apparently they didn't care.

Just out of curiosity, are you guys on street tires lowering the tire pressure at all? Would help immensely, even on 235's. I'd take them down to about 23-25, clean them off in the burn out box and see what happens.

You'd easily hit 12's if your legs were long enough to pin the go pedal to the floor. ;)

That won't help at all unless they are drag radials. The sidewalls on a regular street radial do not flex therefor do not benefit from lowering air pressure at all.

Also, if you are on regular radials, don't do a burnout in the water box. Drive around it completely avoiding the water. Depending on the tire will depend on what type of burnout you need to do. Some tires if soft enough will benefit from heating them up, but some other stock type tires will just get hot and greasy making traction worse.

Just my opinion..

Doing a small burn out is good regardless, just to at least clean the tire off. Also depending on pressure it is good to lower pressure even on street radials. Lots of us have done a lot of testing with Invos, which are recommended to be at 35+psi but at the track we all do much better with 20-22 in them

Most modern tires recommend 35-45psi for fuel economy and there is NO WAY you're going to be able to hook up on a rock hard 40-series tire with ~400hp and a stick. There is a difference between "take some air out" and "take it down to the air pressure you run in a slick." Most of these guys would get a better launch at ~25psi than they will at 40.

*edit, treed by junkie

I agree a quick spin of the tires is good to knock the rocks off or any accidental moisture the tires may have picked up going around the waterbox. I usually just do a quick spin.

While my times are embarrassing, I can't believe how consistent I/my car was...especially running on street tires with a stickshift. .005 difference between my two passes? that's insane.

113 mph...I should be in the low 12s/high 11's. Oh well. I'll leave the ET on the track and save my tranny. Though I have my answer to my other thread. Screw a blower, I am going to start looking at a magnum swap. What good is 200 extra hp if I run 12's at 125 +mph? That's just foolish.

One thing is for sure. The AUTO is the way to go fast in these cars.

The idea is to remove the air pressure enough to make as much of the tire as possible contact the pavement. The compound of the tire with how soft/hard it is will create the traction with heat from the burnout. I'm with you there on all of that.

A tire like an Invo that is a real performance tire being a softer compound will benefit from a good burnout. Also, being an aftermarket tire is most likely a larger tire as well. I can definitely see what you are saying applying to that.

I just don't see it applying as well to someone on a stock 235 Pirelli that is a harder compound designed for all seasons and the side wall is not meant to give at all.

I also agree with you that some people let out way too much air on a street radial thinking they are getting the same effect as they would on a slick. The same could be said for a overly inflated tire.

The auto are definitely much easier to make faster. I agree they are way to go if someone is planning on tracking the car often. But my car is mainly a street car and I still prefer to row gears on the street. Gives more of the drivers experience feeling connected to the car.

:buttkick:

Everything is good. Trying to keep stuff offline. Thanks for understanding

Nic, what was your best mph saturday night?

This.


Taking air out of a street tire is not to make the compound work better, but to let the tire have more give.

All I know is, every time i've gone to the track on street tires, i get better 60 foots with the tires around 24-25 psi compared to 35psi

118

It was good meeting a few more of you guys. Hopefully next time we all hit the track I'll have the converter in. I can't complain about the track though, with those DR's and 3.15 gears I was surprised the car had enough power to even do the burnout!

That's some good mph for a lil 302 with bolt ons.

agreed! That mph is badass for a bolt on car. Perhaps longtubes/boss intake make a bigger difference than I gave them credit for.

I know for a fact the longtubes work on these cars. Nic and I raced before his longtubes and we were close. After his longtubes there was an obvious MPH difference because he had a nice steady pull on me from a roll.

We had a boss out there running 10.50's at 133 mph using the stock 6 speed.. Car has a d-1, fuel system to support, headers, and some control arms. Other wise bone stock suspension with full interior and nothing taken out.

It would have run better times with an auto.

That's the beauty of a power sliding seat. I could easily reach the firewall with the pedal. Full foot to the floor. :D

You didn't race though, so you can't give me much crap. :p

And FWIW, I aired my Michelin Pilot SS down to 25-26 PSI from 32-33ish. I probably could've done more, but I didn't feel like waiting over an hour for the shitty "mobility kit" air compressor to pump my tires back up from 20 PSI, because I wanted to get home. lol

Not everyone wants to just push down the peddle and go and try to set records. I like shifting through the gears. It's a lot more fun.

The Shell station one mile up the road has free air.

Haha, I was thinking the same thing. But there's nothing like getting a freak rainstorm while on slicks with 10 or so psi!

I own one of each. I'll take an auto over a stick anyday at the track.

I find it hilarious you M6 guys saying it takes a "man" to drive a stick, etc. when they have no clue what it takes to make an auto work to where all it takes is just mashing the gas.

When you are laying parts across the track creating a mess for the crew to cleanup and causing delays, come talk to me again about how much better that manual trans car is.

You do have an upgraded driveline with all the necessary support to withstand 6K RPM launches on slicks right?

:lol2::hidesbehindsofa:

I think your missing the point of what most people are saying. You can't compare times between a m6 vs an auto with a stall. The auto is going to eat the m6 out of the hole and hit the shift perfect every time because its computer controlled. No human error involved. But he and a lot of other guys, myself included like sticks for our sports cars because they are more fun to drive on the street. If I was going to race my car every weekend then yes I would do an auto but I don't so ill stick to my old 5 speed.

Fixed....lol...sorry, couldn't help it! A6 OWNERS UNITE!

X2 exactly was never saying a manual is better for the track then an auto. WBT man you might want to read a post twice before you post cause just because some thinks differently doesn't mean they are insulting you or better then you.

LOL nice Doug, ass.

Its cool my sister has an auto mustang too.... Im with Jeff on this one. If it is a pure drag race car sure auto is better but it is a lot more fun to slam the gears on the street and at the track IMO. You could my mom in an auto car that is set up right and give her a couple runs and she will be running close to the same any anyone else in that car.

an auto will tell you what the car can do, a manual will tell you what the driver can do with that car.

I get it and I made a few points that were missed.

After a couple of days posting here and seeing some of your history, it seems as though you do a lot of talking and not much producing.

Less posting, less talking, more producing.

Now back to the upgraded driveline thing...do you or do you not have your shit together to support 6K RPM launches with your car. If not, the exact scenario I listed is going to happen in which an auto car would serve you better if you want to meet the goals you have set. Fucking around aside, I am dead serious about this. If you get a good tire on that car, and you will have to launch at 6K+ to get a good time, and your driveline is mostly stock, you are going to be SOL. Expect a tow truck to take you home unless you trailer.

I say this based on experience.

Very true. My old dragster ran the same times run after run. Any of my friends could have gotten in and drove it to that time after some practice runs. It was set up to shift exactly where it needed to and I knew exactly what rpm to launch at. The only thing I had to worry about was going straight and the tree. Hell I only saw 2 of the 275 tire class running faster than what my old ride did. So I think I have a little experience in these matters.

Back when autos were 3/4+OD (like the 4R70W in my F150 and 4R100 in the Lightning) sticks were the go to transmission for the track it seems, just because the autos could tend to be lazy. Nowadays with the new 6R80 and all the others out there, autos are some badass pieces of equipment they put into their cars. If I didn't have it out to own a Mustang with a stick (being my first Mustang ever) then I would've gone auto simply for reliability and ease of mind driving in traffic and such. Plus the girlfriend could drive it. LOL

I will never say it takes a man to drive a stick at the track, but I will say it take a man to drive a stick as hard as an auto at the track.

You don't worry about my history. And I have a one piece DS and that's it as far as the driveline goes.

I can sip coffee AND downshift from 5th to 2nd in 1/4 of a second from a 40 roll.....what's more fun than THAT on the street! LMAO!

I can get behind that.:favorites13:

and clutch, flyewheel, DS loop?

Actually no DS loop. Damnit Tim

actually shifting my car :driver:
