Power brake to 2000rpm.

 

do you all launch with the OD/TCS off?? I always do on the street and it seems to launch real
hard off the line.

nice time btw,personally I think I'll be lucky if I hit 13.8@100,C&L racer intake/90 octane tune,auto.

 

Answering the original post. Sorry, had to start all over and make a new screen name.

I have a 06 GT auto. She has 3.73's in her with a TCI 3000 stall torque converter.

Her best time is a 12.9 with a 1.74 60 ft time. A few things I have found but launching her several times:

TC off, OD off (Your not going to hit your top gear anyways but WTF)

I footbrake to right at 2000 RPM

I have Nitto DR's running 20 PSI.

Will work on my sig later!

 

yep...
Power braking around 2000RPM... i give it a little more to about 2500~3000 RPM
and i still dont spin... but thats because of my 20" rims

 

i power brake at 2000rpm as well with stock tires

 

will 410s help alot. 12.90s maybe?

 

Dude if your running 13.2 you should be giving launch lessons, not asking for them!

 

Ya got that right! To the OP, the S197 GT auto's I had don't bark a tire from a dead hop. They didn't powerbraking either unless I spun them up in a brakestand. It dead hooks which is a good thing I suppose. 4.10's with your tune should wake it up a whole lot. The aluminum driveshaft will make it feel snappier and more responsive. Gears, driveshaft, tune, and intake will net you high 12's with DR's if you can slingshot it...
