Exactly. This is why I stated the torque differences between the motors will also have an effect. I see the math as just a start point with additional changes from testing necessary to achieve similar lap times. The Mark Thomas motor is rated at about 13,650 RPM per Robert L. A little more RPM but less torque. I'm going to start with this motor and the same gear ratio (9x25) and see how it goes.
