Re: [ST] Higher RPM for racing?
(Torque) X (rpm) => HP
So your 6000 rpm motor has TWICE the torque of the 12000 rpm motor.
Somebody did a very bad job building the 12000 rpm engine.
A wide power band (flat curve) is always a good thing. But for the track you only need a power band as wide as the spacing between gears.
