Light weight flywheel?

more than likely. its indirectly the light flywheels fault i believe. its more likely after installing light flywheels people believe their cars to be able to handle more revs than they actually can. then 10. 11. 12. 14000rpm. BANG! plus if your flywheel doesnt give way to such rpm, internals may, if not upgraded to meet the task.

On top of abuse and RPM it will depend how the lightening is done, what it's made of, outer diameter.... Any clutch spun too fast will be destroyed, the question as previously noted is will the rest of the system withstand that RPM. I would trust an Aluminum flywheel from Racing Beat and probably Fidanza. I will likely be buying the ACT prolite flywheel soon for my build (350+ whp) which is chromoly steel I think.

well right now its just hualing *** and being dumb.
but the car will be for road race (one day... :/ )

i've seen just about everything else road racing, but i don't think i've ever seen a flywheel explode.
this is what racing beat says "WARNING: None of the Flywheel or Clutch components shown in this site should ever be allowed to exceed 10,500 RPM under any condition. This same RPM limit applies to stock components. You must use an engine RPM-limiter to prevent excessive RPM. If your engine is capable of exceeding 8,500 RPM you must install a transmission scatter shield, or ballistic blanket. Failure to implement the above may result in serious injury or even death."
and its probably good advise, no matter what flywheel you have.

2nd that^^^
Also, don't drag racers usully use a heavy flywheel the store energy for a hard launch? You may be worried about something that isn't really an issue.
I just had a friend explode a clutch at Sebring back in Nov. in his vintage RX2. Destroyed the bell housing, broke the back plate of the engine where some of the bolts go to hold the trans and engine together and pretty much cleaned everything off the firewall. Aluminum flywheel was intact.

25lbs cast versus 10lbs of forged.
hmmmmm, i wonder which will explode first..
i have seen some old school light steel flywheels begin to crack but most current light flywheels are aluminum(with replaceable high tensile friction disc) or chromoly, both of which are multiples safer than the original heavy as hell cast unit. there is never a guarantee when you start pushing near or beyond 10k RPMs though.
