The motor is something like 12" diameter. Should be able to make some pretty good torque.
Two other guys that I know are using the same motor in Ford Ranger EV conversions. Of course that's with the motor going on the transmission in place of the engine, not going onto the driveshaft.
I'm sort of waiting for both those guys to give me some real-world feedback in how well the motors work for them, if they run into any issues, etc.
Physically, the motor is bigger than a Warp 9 and smaller than a Warp 13.
I have a couple photos of the motor at:
