do i have enough gear or not enough?
currently i have a mild 466 with 28 inch tall slicks and running a tko600 5spd with a 2.87 first gear and 3.7 gears. i trap at about 108-110mph and barely use 4th gear and i'm crossing at 5000rpms in fourth.
i'm going to be getting back my 521 from scotty j with about 640ish HP. with the 28x10.5 slick i have now, i went to the track with it last time and i was all over the place until i made the calvert as stiff as they recommend.
before that motor is going in, the car is in the fab shop to get the mods needed to fit a minimum of 29.5x10.5W slicks. that is 30 inches tall and was possibly thinking about going with 31x13 slicks if i absolutely have to relocate leaf springs. i'm going to be limited with a 15x12 with a 7.5 or 8.5BS.
this is a 73 mustang.
so if i go with a 30 to a 31 inch slicks, do i have enough gear or not enough? i'm trying to nail down a consistant 11.0'ish ET for the brackets and something that will handle the 125hp shot of nitrous of course.
any input would be perfect guys, thanks!
