i went to the track today and my best time was a 15 flat
heres my slip

Reaction :.221
I1: 2.432
I3: 9.830
E.T 15.064
MPH 95.216

im an auto with a comptech icebox and a set of yokoha AVS ES 100 tires

just wanted to know what exacly im doing wrong because i here many ppl runing in the high 14 almost stock

 

First thing is your 60-foot... its horrible for an auto CL-S (I am assuming you are auto)
with Yoko ES100's!!! I am assuming you 'bogged' off the line - you need to torque-break
and then launch.

Your MPH looks okay for just CAI on an auto CL-S. If you can get your 60' to around
~2.1, your E.T. will drop to about 14.7 and mph to 96. Next would be headers and then
you are on your way towards low 14's at 98-99mph.

Good luck!

 

thanks for the advice but up to what rpm should i break torque till
yes im an auto
i ran with a full tank of gas too

 

Break torque till the rpms cant climb anymore (I think thats called the stall point) Also run with 1/4 tank or near empty.

 

take out the spare / jack

 

i was breaktorking but i guess to much noticed alot of wheel spin i heard the best rpm is like 1.5 to 2
what have u guys done with autos to get a good launch

 

yea dude.. work on the launch and you will see an improvement

i recommend maybe taking some performance driving lessons... they cost a bit but trust me you will learn a shitload.

My worst times at the track have been w/ the brake-torque approach. I just spin and spin and spin. Lower your front tire pressure down to about 28psi and pump the rears to 40 or so. They'll look pretty flat in the front but you'll get alot more traction which will give you lower 60' times and allow you to launch a little harder. Listen to me, I've only been to the track twice in my life and already I'm giving advise...hahaha!

 

my advice is forget about BT ...hit it.pause then feed it the rest...no need to go less than 25 psi...run on e...no spare no jack

 

the full tank of fuel alone is costing you .1-.2 and ~ 1 mph.


like everyone else said, drop your front tire pressure to ~ 25psi

i recommend you gate shift the car. which means putting it down in D1 to start and manually shifting it. remember to move the shifter w/ 2-300 rpm before redline to compensate for the hesitation.

TB up to 1500-2000 rpm, roll onto the throttle until you have traction then mash it
