ok my g35 coupe ran a 13.81@101 BONE Stock on et street slicks.

now im going to pull rear end apart next week and install the 3.9 gears.

mods i did after my bone stock run to the car is the crank pulley. jwt pop charger going in next week along with crawford cats and the crawford plenum

on most of my cars stangs and stuff going from a 3.42 to 3.73 gained me 4/10 in the quarter. now im wondering if anyone has done this change and taken it to the track. i have no traction problems at all the car ran a 1.8 60foot time at the track first time out and i can crack 1.7 if i launch harder

 

I didn't drop et at all, but I gained 2 mph on the trap. With the slicks, I think you will be in the ballpark of 13.6-13.5.
