I TOTALLY disproved the rule of every tenth in the 60' is 2 tenths in the 1/4. I saw an equal gain, tenth in the 60' gave me a tenth in the 1/4 (if that). Raced on a bunch of different tires, stock gear vs. 4.10 gear. I've had every short time from a 1.58 to a 2.1 (thankyou, NITTO) 12.90's seem to be a rather lofty goal. What all have you done since you ran the 13.6? You don't see very many Bolt-on 2v's in the 12's. I have yet to see one, actually. There was no way my car had a 13.0 on it on motor, not even close. Maybe I could have gotten a 13.3 in perfect conditions, but i doubt it. I'm reviewing the vids of it right now and the runs look good, only thing that could have improved them was powershifting. Sorry for the thread Hijack...but i know u don't care JD lol
