Some very important information that needs to be added to this thread. The Warp HV motors cannot handle the same amounts of torque as the Warp motors. The interpoles will not handle the huge amounts of current. For example:
My Warp & TransWarp motors are only rated for 180 volts, but can handle over 2000amps for a short period.
Warp HV motors can handle higher voltage, but at a loss of amps/ torque.
It all depends on what your car is built for. Long distance racing, definitely the HV motors, 1/4 mile drag racing low voltage Warp motors. Your car MUST be geared to match your motor/ controller/ pack.
