The next "HP loss" is caused by rotating mass. It takes a certain amount of HP to "turn" the internals. At steady RPM, assuming the same frictional and pumping losses, the HP to turn a 25 lb rotating mass is the same as to turn a 2500 lb mass.
WebMay 11, 2009 · Flywheel vs. Wheel HP As most people know, there are power losses through the drivetrain so wheel hp is always lower than flywheel hp.
