I found with the 5:1 ratio and the 55T motor on 12 volts, plus the 3:1 axle diff ratio, the speed would be almost identical to the stock Wedico trans in 3rd, with the Buhler motor. I expect no shortage of power, .....

I think your math is a bit out Nathan. :P

I find my trks have a good combo of both power & speed with dual Beuhlers, tam trans in 2nd and I have an additional 6.2 reduction within the twin motor coupler & tam transfer case. I forget exactly what the stock reduction is in 2nd with drive axles (17:1?)... total reduction is approx 105:1 with motors running around 5000rpm.

What rpm is the 55 turn 12v Novak motor?
