Re: help choosing gears for tranny for orr
Okay;
Heres the way it works for the engineers at Auto Gear in Syracuse NY (T5 T56 TR6060 and 4spd manual parts)
Take your rear axle ratio (3:1) x your 1st gear choice. The ballpark is to get close to "9." As an example: 4.11 (rear gear) x 2.20 (1st gear in a Muncie RockCrusher) = 9.042. So; if you have a 3.07x3.20=9.8. Thats a WICKED deep 1st gear, too much honestly. You should really be looking for a 1st gear in the 2.98 range. If youre stuck, go with the 3.2 first gear I guess. a 2.04 1st is going to need at LEAST a 4.11:1 rear to get the car to move, 4.56 would be better.
