When raw power is all that matters, nothing can beat a dual 11" motor. This beast is designed with racing in mind (parallel connection is best suited for racing while series is to be preferred for normal driving) and rpm are optimised so it achieves good rpm even under severe overload. The assumption is that a 300-350V controller is used with at least a 1400A rating so that full advantage can be taken of the motor. Stator coils are beefed up so racing stress is easier to the motor. Standard delivery is of two axially joined motors but side by side combinations with a chain are also possible.
