Engine Balancing - We strongly recommend balancing the rotating assembly if you intend your race engine to run above 8,500 RPM or if the engine is a non-standard assembly. The rotating assembly includes both rotors, main pulley, front and rear counterweights, and the eccentric shaft. We also recommend balancing the pressure plate and the flywheel on the rotating assembly.
In our experience it is not necessary to re-balance a stock or mildly modified engine operating below 8,500 RPM if the rotating parts were originally intended by Mazda to be used together.
