It can beat it.
This speedo is whole different world when it comes to gearing, believe me. It works by using the motor's most efficient range. You can use unbelievably low FDR's and stay cool
Gearing short is exactly the thing you do not want to do with a long straight. You will lose punch and top speed, raise temps and fade at the end of the run. High rpms draw a lot of current just like excessively tall FDR's
But there is an exact point in the gearing where the motor suddenly wakes up and produces a load of torque and high top speed with low temps
13.5 go out at 6.20 - 6.40 mode 9 for 2-3 mins and temp. Std 30 deg motor timing, there is no advantage to advancing the can. If temps good go taller and see how it goes
Fixed timing 25 is about the maximum a std rotor can take before overheating. If you use a strong magnet use less fixed timing
