I think this part was mint for me . I will be running a 5.50-1 to a 7.30-1 gears in the car . But if you really think I should use the DC motor in my car .....well I guess ....OK . "But" , 200Ft lbs is great at 1500 RPM on built 5.0 H.O . My street racing engine only had 175Ft lbs at 1500RPM . And if that AC-76 set-up can do 8000+ RPM , I'm in heaven !!Now, make that a 3400 lb vehicle and 2 km long 8% grade and I would expect around 800Wh/mile and around 50kW power at the same speed, and about a 2*1.06*50/21 = 5C temperature increase. Peak shaft power of the motor with the 650A controller should be around 60kW with a 115V nominal pack. Hopefully this is within +/-30% of actual performance you would get, but no guarantees.
