its just that I heard the lighter the flywheel the faster the revs go down , so you have to shift really fast ..

I'm curious, could someone explain this more? Maybe its due to less weight reducing inertia force?

Kindof... There is less spining weight, so in between pistons strokes, there is less to keep that enging spinning. I guess intertia has something to do with it... but, thats the sacrafice you have to make to rev like a crotch rocket!

I want to get the Zex flywheel. It only weighs 6 pounds!

I have an ACT Prolite and an ACT 6 puck. I bought the car this way. It's great, but the inertia loss is a pain in the ***.

From everything I've been reading, boosted engines get the most benefit from lightened flywheels. Especially turbos, it helps reduce turbo lag to not have to spool both the turbo, and return a full weight flywheel to optimal rotating speed to be grabbed by the clutch.

This is just what I've read. I'll have to test it when I get my CRX-T put together.

so if I'm running an auto, an 6 pound flywheel would be perfect?

Autos don't have flywheels. They have flexplates. A completely different setup.

So whats this loss of inertia ****? Is it only good for a lightenned flywheel for neutral revs or it makes the rpm rip in all gears? But the rpms drop fast when you shift?

Dont really get it.

Objects in Motion tend to stay in motion. That's inertia. Your counter balances on your crank work the same way. As your rod end rotates around the main, it creates force in one direction, the counter-balance keeps the origin of rotation in the center of the crank, even the load across the main journals.

They help keep what's moving, moving. When you lighten a crank counter balance(knife-edging) or fly wheel, you're disrupting the engineered balance of the crank or fly wheel, wherever you're taking weight from. The friction of the parts against each other(rings, bearings, even valve springs) 'help' decelerate the moving parts.
