Re: will a LW flywheel help you rev quicker? (BIGGEE TALLS)
Yes. Lower rotating mass means less work the engine has to do in order to accelerate. As you probably have heard, a flywheel stores energy. The heavier the flywheel is, the more energy it has stored. However, that energy didn't just come out of nowhere. The heavier the flywheel, the more work the engine has to do to rotate it and accelerate it.
I believe it's been said that each 1lb reduction of the flywheel gives a similar effect to 4lbs reduction of bodyweight.
