Bear in mind that assumes the same RPM. If you ran a large engine at small engine speeds the flywheel would burst. The safe maximum speed for a spoked cast iron flywheel is roughly 570,000/diameter in millimeters. So for a model with a 4" flywheel it is approaching 6000rpm*, but for a fullsize engine with an 8foot flywheel the safe maximum speed is just about 240rpm.
