But, I don't think so. Here's a reasonable quote from one of the many vendors selling lightened flywheels:

How does a lightweight flywheel add horsepower?

Adding a lightweight flywheel does not add any hp to the engine (it can’t, as any engine in any given state will produce a given hp based on the temperature and the air density).

What adding a light flywheel does to your drivetrain is to lighten the overall reciprocating mass attached to the end of the engine’s crank, thus allowing the engine to rev faster thus accelerate faster.

I think that is the real story.

And I think Adrenaline had it right.
