jus curious if too much is taken off, wont the engine lose its momentume. as all the engery will be stored in the flywheel while rotating..? by removing the mass u lose momentume.. is dat correct?

Man looks like a lucky fail!

 

That disc out of the centre, was it roughly the same diameter as the mating face on the crankshaft? Makes sense, that's where the highest load from the clutch pressure Will be concentrated.

 

I had a flywheel shear all it's bolts once. Dug a groove on the inside of the bel housing....

 

Yeah it was and it corresponds with what altezzaclub had said

 

You need enough to support the ring gear and the pressure plate pulling the rim backwards against the center.

 

This one obviously didn't like the near 9000rpm it was reaching.

Yes that is correct.

Yes that is correct.

 

any clue on the wieght before these motors start to suffer from lightin it ?

No.

Yes A lighter flywheel at certain revs will have less angular momentum.

 

The advantage is that because it doesn't need so much effort to go from 0-9000 revs, it accelerates quicker. Reducing flywheel mass is akin to mKing your car lighter so you can accelerate harder.

Sometimes people say you lose torque from lightening a flywheel but you don't,

the engine still makes the same torque but it reduces the ability to store it.

Also has been said it make engine more powerful but not so, it reduces the load

the engine has to drive hence the performance effect.

 

A standard flywheel is used to smooth out power delivery and store torque to make

a more drivable car but at the cost of performance. Lightening a flywheel is most

effective from 1st gear and reduces up to the highest gear, probably one of the

best upgrades for the cost, just remember hillstarts may need a bit more effort

and cruising suffers a bit.

Would it not have split between the PCD of the pressure plate bolts and the friction surface if that were the case?

The whole flexing of the flywheel from the clutch and pressure plate at high rpm caused it to split where it meets a solid surface.

So...

 

We needn't worry about the mighy 4K blowing one apart! Particularly if we're not racing them, or carving stupid amounts off.

 

A lightened flywheel is one of the most effective per buck at quicker acceleration, but you will stall the car a few times until you're used to it. It drops revs faster when you let the clutch out.
