well im thinking my belt is too big, so the tensioner is not applying enough tension.
i raced a s2000 with intake header and exhaust and beat him from a 50 punch on the 3.5, had to start it in 2nd or else he would rape me off the punch like you said.
when you say im around where you were with your 3.4, im guessing bc yours was tuned and making the most power out of the 3.4 setup? E85 really isnt an option for me, 93 octane is what im able to use. not enough E85 stations available around here.
