I posted a thread in here a while back about detonation with my '96 GT. Well I installed some new plugs in it that one of ya'll recommended and it has went away. The mods I have is 6# Vortech, TRW dished pistons, conical filter, Borla cat back, and found out I have 4.30 gears. I went to the track this last weekend and pulled off a 13.45 @ 102 w/ slicks. There was no traction whatsoever, since the track was so cold. I pulled slicks off and put my street tires back on and rolled off the line and managed a best of 13.79 @ 104. The mph. is good, I just need some traction. I figured a sticky track w/ slicks I should be looking at 13.20's. I really need to change to 4.10's, because at the 1/4 mile traps I am running 5,900 rpms in 4th gear.(5spd)
The 4.30's I think are slowing me down up top.
