N20/11's ?
 

alright ive ran ab est of 13.3 at 111mph in an all stock 2000 Z28 A4 with an exhaust cut-out and a handheld tune. ive just added a 100 dry shot do you think itl break 11's? if it hooks

That is a very high mph for a 13.3 ET. I am thinking your 60 foot is pretty bad. You need to trap around 113 to hit an 11.90. Get some better tires along with the 100 shot, and you MAY hit your number.

My bet would be for low 12's but with good air and a nice launch...maybe :)

I think you could make it, I'm running the same times on motor as you are. And on the spray I'm getting in the high 11s. I know I'm spraying a 150 shot, but that extra 50 is getting eaten up in the additional weight of the GTO.

if it hooks it will run 11's! good luck!:D
