The Un-Desired Effects of running a Lightened Flywheel on a stock setup?

what are they?
like putting a racing flywheel on a stock RWD 4age?
how does it affect the performance?
what characteristics would the car display?
what is the function of a flywheel?

Couple of things, to my understanding:
1) The engine will rev quicker as it has less inertia to overcome with the lighter flywheel.
2) However, it is easier to stall on takeoff (if revs not held properly) as the engine now has less momentum, so the revs are more critical. Not sure if that is the best way to explain it.

I've just gone from an aluminium flywheel to a steel one on my ZE and there is a definate difference.
The light 'wheel definately gave the car more of a race feel (the sound when you free revved it was awesome), but, it was a little trickier to drive. It's a subtle difference, but, it is there.
Mine had a problem where the steel plate had come loose from the aliminium, so it's hard to be specific about the differences, but, I definately prefer the steel flywheel to the aluminium one...

Would these sort of problems arise on a 3sge, i imagine that they would. How differently does it rev, is it a smoother curve or just a lot quicker to rev out?

Force=Mass.Acceleration
as you have decreased the mass of the fly wheel, by applying the same force you will see a proportional increase in acceleration.
This will applying for all fly wheels, on any sort of car. The opposite will apply for a heavier fly wheel.
However as momentum = Mass.Velocity, the momementum of lightened flywheel at 2000rpm will be far less than the normal flywheel at 2000 rpm. This will mean that the time the lightened flywheel will reach the 2000rpm much faster, however, it will also decellerate much faster as well. Thus making the lightened flywheel harder to laucnh normally eg. from a set of lights or a hill start.

Basic physics then makes sense. So really all that you have to do is work on throttle control and give it a few more revs on launches, would adjusting the idle help a little? Just gettin some ideas coz i wanna rebuild with heavier cams n was thinkin bout lighter fly.
Cheers mate
