I've been neglecting to post these forever.

Tools needed:

32mm socket, 36mm socket, Impact wrench, steeringwheel puller

CORRECT WAY to pull the gears:


Use Blue Loctite!


Slips: before-braketorque, before-regular, after-braketorque, after-regular


Before (Stock) using Brake-torque launch:
R/T: .767
60': 2.742
330: 7.209
1/8: 10.694
MPH: 71.24

Before (Stock) using regular "Floor It" launch:
R/T: .541
60': 2.751
330: 7.204
1/8: 10.693
MPH: 71.25

AFTER (Final Drive installed) using Brake-torque launch:
R/T: .510
60': 2.643
330: 7.062
1/8: 10.513
MPH: 72.09

AFTER (Final Drive installed) using "Floor It" launch:
R/T: .624
60': 2.541
330: 6.922
1/8: 10.124
MPH: 73.34

Verdict: I shaved 0.57 seconds off my 1/8 mile time, and gained 2mph. Braketorquing is bad.

This would probably translate to a 1+ second improvement and 4-5mph gain in a 1/4 mile.

I didn't feel it was fair to get 1/4 mile times since the car is turboed. Since it doesn't spool in 1/8 mile, these results should be repeatable by a modified nonturbo.
