I'm not sure it would make a big difference 1/4 wise as you will be changing gears more and it makes launching more difficult. This seems to be an item that track jockeys and road course runners will use. That said I want one, real bad.

I picked up 2mph on the trap, but could not better my et. The Tilton is the best 1/4 mile bang for the buck.

I dropped half a second after switching to the 3.53 final drive from the 3.32 in my 5AT.

yeah but 5AT don't have to shift as much, and when it does shift it's lightning quick anyway

So I guess its a little different, huh?

i dunno, most i ever heard with the 3.9 i think was a .2-.3 sec improvement in the 1/4 mile in combination with the 7100 redline, but who knows

How were your 60' times? Were you running street radials or slicks?

faris13

yea that's pretty much what i figured...zillinois you were running like a 13.2 with the tilton, 3.9, and raised redline right?
