Coil gap on 6608 ARC Limited Mod Flywheel

A better and safer test might be to do use an inertia dyno and do a run down test. Basicly once engine reaches max or specified rpm it measures the losses as the motor revs down till it stalls. Performance trends I think is the software.

The reason for stronger magnets is so you can achieve better spark, so wider gap's can be used; both coil and plug. Have fun
 
The rare earth magnet is the performance industry standard. It is a quality piece, produces a strong magnetic field, and is in the pipeline for high requirement usage.
Interestingly enough, China is the leading supplier of rare earth magnet ore. It is a subterranean material.
