Default Re: New D&D Torque Motor (4:1) - Not Seeing 40% Torque

After adding the motor, I was expecting to see a little more power and speed going up our hills than I am actually seeing. Am I expecting too much from a golf cart? Do I need to continue down the path adding a 500amp controller? What is 40% more torque suppose to deliver if not pull up a hill at higher speed than 2-3 mph.
Been there with the 4:1 and 36v. Only 48v will wake it up significantly. The stock motor has zero torque so 40% more than stock is still zero! Using a high current (500A) contactor I bypassed the FNR, the solenoid and the speed board (controller) so effectively eliminating any current/voltage robbing components with no improvement.
