Simply put, that is the "flywheel effect" that gives you the so called increase in horsepower. There is no argument with the laws of physics here. Only the concept that power is "created" when it was there all along. Run the heavy motor and the light motor at steady state rpm (Nascar, superspeedway) no difference. Same motors short track with many rpm changes, the lighter motor will be the winner. It is all in how the testing (or use)is done and results recorded. By going lighter, you are not increasing power, just releasing it.

My guess is it's minute unless significant weight differences. It's probably not ever measured because when forged rods are introduced, other factors changes as well.
