I went to the track today and ran constant 13.6x with 2.2x and 2.3x 60' times.

I'm unsure why i'm running so bad or am i running right for my 60' times, plus i'm unsure about my tuning right now


My car is a 99 a4 with the following.... lid, hooker headers, hooker orp, magnaflow, and the diablo predator

 

u need to hook better...your 60 foots could be a little better...

what tires are you using

 

yokahama avs sports............ the track had a new launcing pad and everyone was getting bad traction but my mph was only between 101-103 and i thought that i should run better with headers

 

With your mods I would think you could run ALOT better than that. I would think very low 13s, and if you got some sticky tires maybe high 12s.


Edit-What is your elevation/location and what were the temps and humidity?

 

What rear gears do you have? Are they 2.73's? I would get some 3.73's and a converter.

 

i have a trans am ws6, so i have 3.23's.........

temperature was under 70..........

Could my a/f ratio be messed up that bad?

 

Probably was just a bad day at the track Those mods should be near 13s flat... Im still wondering what mines will run ...
Good luck next time at the track!

 

Your 60's are killing you.You should be 2.1 at the highest with an auto.Drop those bad boys down to 2.0 or lower and your times will be right where they are supposed to be.

 

Yeah hopefully next time my car will run low 13's but my mph was still so low for what i have,,,, a stock ls1 should be able to run that mph easily.......... hopefully getting my car on a dyno will tell what is wrong
