Flywheel weight?

OK, very slightly less gross vehicle mass with a lighter flywheel, but engine power and gearing are unchanged ..... so how does a lighter flywheel allow quicker acceleration?
Quicker to blip the engine - yes; quicker acceleration of the vehicle? ....no

I need a more convincing argument.

So the argument goes, Glen, a reduction in the angular moment of inertia results in less angular momentum to accelerate during WOT operation.

If you do the math the overall difference (including vehicle mass) is skinny but — maybe. If you take a car to the track and try to read it on a time slip it is below the margin or error in the timing system, which begs the question why are we doing this again?
