What everyone wants to drive is a personal choice. I personally wanted a Boss 302 and a stick is what you get. I like driving my car. I love the control of having a stick as well the potential headaches that can come with it. I have taken steps to make my car as safe and reliable as possible but let's face it, things break as long as you are pounding on your car. You make enough passes, or run enough times, something will break eventually.
We have nearly 50 launches on a track in this car and thankfully have not had any major problems. We have however, continued to make improvements and take safety measures as HP has increased.
Not taking sides, auto vs. manual, just making a point that it is all about preference and stick is what I enjoy driving.
Just ask the auto GTR and auto Trans Am that I politely schooled Saturday night.
If you have raced long enough, you know that there is always someone faster. That is why we do this...we keep going back for more HP. That is what keeps us going and keeps guys like TS in business
I know there are faster cars out there than mine, but I love what I have, and had a blast seeing what it would do on the 1/4 mile track. Each time I make a pass, I learn something else about my car. BTW, I only launch at 5K, not 6.
That is what it's all about, enjoying what you like to do. I didn't get a chance to see your car run but heard good things about it.
On the manual trans stuff, I just hate to see stuff break when it doesn't have to. It is relatively expensive to get the driveline up to snuff but makes for a safer, more reliable car. It also gives you room to grow with power.
Most build their cars from front back vs. back to front and hopefully with some shared experience everyone can enjoy their cars how they were meant to be.

The ET streets are the DOT slick, right? I've always heard that manuals need to go with something other than DRs, because they are too stiff to take the drivetrain shock.
Okay finally read all the posts I missed lol. Back to the stock tire guys. I had lowered my psi to 20. I've tried 32psi(what I run on the streets) and was terrible. 20psi seems to be a decent psi. I'll try 25 next time. With my setup, cai/bama race tune, 3.55 gears axlebacks. I was running consistent 13.1s spinning 1st and getting sideways in second. Couldn't seem to stop it. Had traction in third for once(that I've been fighting at Northstar) trapped 113

I think I should've gone lower on my PSI as well, but oh well.
Would, but Stephanie has her surgery so I will likely be helping her.
wbt, will my 3.55s pose any issues with the 28" tire? I assume not since that will just move me into a slightly lower RPM in 4th through the traps.
It's not optimal but not as bad as running a 4.10 where you would be shifting into 5th. 3.73 would be best with a stock intake and 28" tire. 3.55 isn't a bad gear to run with your combo.
Stock tire size on my '12 was nearly 28" tall. I run 295/55's which are about the same height as stock. Car came equipped with 3.55's from the factory. I cross the traps at 7200 in 4th (MT82). 28" works quite well with 3.55's.

Solid point, but you are also going 130+, he does like 114... He would be MUCH lower in the powerband thus killing his time. I think he should get some 26 inch tires personally so it's as close to redline in fourth as possible.

Assuming my redline is set to 7200 RPM, in 4th gear (1.32:1) with 3.55s and a 27" tire, I'll be turning around 123-124 MPH.
A 26" tire would basically give me 118-119 MPH at 7200 RPM redline
I think a 26" tire height is my best bet for the power level I will have my car at for a long while before boost. I should never trap more than 118-119 if I'm around 420-430 rwhp (after E85 conversion and maybe a TB). Right?

You will want to give yourself a little cushion. Peak power with the stock intake is going to be around 6,500. 118 with a 27" tire and 3.55 is ~6,900.
I'm right at the stock rev limiter in fourth gear when crossing the quarter mile.
3.73s
28.5" tall tire (305/35-20)
114.5mph
I dunno about you, but I would expect at least that kinda trap for a modded coyote...

Brent is/was trapping around 118 with his setup consisting of Boss IM, and all those other goodies. I would think I would be slightly below that, but I don't mind going with a 27" tire at all. Actually, that would be nice to drive to the track on a tire setup that wasn't 1" shorter OD in the rear. LOL
But yes, in perfect math/conditions, a 27" tire would but me basically at 120 at 7000 RPM. 120 MPH should be a low-mid 11 sec pass, correct?

soundsa bout right... also, the Quick Times are bias ply, they grow about an inch when they are wound up, so you can prob go closer to 122... Absolute WORST case after you have the tires, bump the revlimiter 100-200 rpm if you are tagging it. Those motors will spin to the moon and not g.a.f.
Mine was shifting into 4th right before the finish line with my 3.15's. It short shifted at 7000. I think I can avoid this shift all together if I just raise the 3-4 shift point. This SHOULD cut some ET as well since I'm removing a shift. Right? Not sure how much though.
