What rear gears are you running? I am running a 3.27 and think it is too tall. I am thinking of going to a 3.73. Looking for opinions.
What do you think your car will trap all out?
Take that and decide on a gear ratio in accordance with tire height you are running that will barely get you through the 1/4 mile at the max rpm you want to turn.
There is NO such thing as needing to run longer gear to load the turbo.
I think the car should trap 155ish. That is why I am leaning toward a 3.73 I run a 28" tall tire.
