I am looking at gear ratios for the M5R2 and lets say we keep the stock 2.73 in the rear. Would there be any bennefit to switching to the truck gear ratios? I am assuming that the gears and countershaft will work in ours from the truck version. A close ratio transmission is a good thing and most will agree with it, right?. Here are the ratios for the following cars. Seems like the truck ratios might not be a bad idea 2-3 seems to be shorter then the SCs gears and that could mean quicker acceleration, but the problem is 1st gear where it seems to be really steep....What do you think, what would be the ultimate set up for an M5R2 in our application.
Early SCs gears
1st Gear- 3.75
2nd Gear- 2.32
3rd Gear- 1.43
4th Gear- 1.00
5th Gear- .75
Reverse- 3.26
In 94-95 the M5R2 received some different gear ratios. This transmission had
the following ratios:
1st Gear- 3.42
2nd Gear- 2.16
3rd Gear- 1.34
4th Gear- 1.00
5th Gear- .75
Reverse- 3.26
Truck M5R2
1st: 3.90
2nd: 2.25
3rd: 1.50
4th: 1.00
5th: 0.80
Reverse: 3.39
Not sure what years, but this is another version of the trucks box
1st 3.90:1
2nd 2.25:1
3rd 1.46:1
4th 1.00:1
5th 0.80:1
Reverse: 3.39
And the almighty T-56
1st 2.66:1
2nd 1.78:1
3rd 1.30:1
4th 1.00:1
5th 0.80:1
6th 0.63:1
Reverse: 2.90
