lightened flywheels - where to get one from?

[supercharged spaniel]

every little counts lol

Yeah, but you still need some inertia for hill climbs and have you seen the mess made when a fly wheel shatters?

[breadman]

The flywheel only needs inertia to help give a smooth idle on a road car engine. Ideally it should be as light as possible. On race spec engines the flywheels are very light indeed, inertia is not important here as idle speed is often so much higher.
Deffinately agree with Nick on lightening a standard flywheel too much though. An exploding flywheel will burst through a bellhousing and then through a bulkhead or tranmission tunnel (depending on engine configuration) with ease. Very messy indeed.

oh dear. my car dont idle anyways with that cam.

So has anyone come to the best conclusion as to wats best to lighten the fly wheel by?

or we still waitin to hear wat the psd one weighed in at ?

[Oily Fingers]

so,  are we basicly saying.

get the crank balanced etc with out having the flywheel done at the same time.  But its ok to fit a lightened and balanced flywheel at a later date??
