it will rev faster with lighter but lose torque higher up rev range so i just go standed.
It will pick up revs faster but it won't lose torque at any revs. It doesn't make any difference to power outputs.

I disagree with that from what iv seen
#18: Re: 180 flywheel Author: gti180boy, Location: StaffordPosted: Fri May 13, 2011 9:47 am ---- Torque is simply force with a rotational component, for simplicity's sake let's ignore the rotational component for the moment. Force = Mass(M) Acceleration(A) so if you decrease M (mass) and leave A (acceleration)constant then you would lose torque, but a lightened flywheel will accelerate faster than the stock unit so if you should see the same amount of torque.
Where am on about loose torque i mean with a lightened flywheel it has less momentum than the stock unit so it can "transfer" less torque to the drive train in the moment when the clutch engages the flywheel. So you have to give an engine with a lightened flywheel more revs to prevent it from bogging as you let the clutch out than you would an engine with a stock flywheel.

The question (for me) is how hard is it for this flywheel to get 'warped' and start causing vibrations like the standard one I've had in my GTi180 since 2005...

A flywheel doesn't "just warp"...
With good OEM clutches, regular servicing of said item and someone who knows how to drive... it shouldn't happen.
#21: Re: 180 flywheel Author: nido, Location: Athens, GreecePosted: Tue Mar 26, 2013 5:19 am ---- Good point!..
Indeed a flywheel doesn't just 'warp' but the ones in our GTi 180s are not really designed to last more than our OEM clutches and -for example- parking every day on a highly sloped road in reverse (like I've had to do for the past 8 years) can be quite a 'torture' both for the clutch plate and the flywheel, even though one tries to keep the rpm low enough and the entire process quick enough. If you replace just the clutch when the time comes but leave the same flywheel, it may not be such a wise option (of course that's open for discussion)...

to a point i will agree but looking at the number of 180's that have this problem i would say that there is a fault with the OEM design.
#23: Re: 180 flywheel Author: nido, Location: Athens, GreecePosted: Tue Mar 26, 2013 3:16 pm ---- My guess is that it's a normal, cast steel flywheel which has been on a diet (to a point) and that the material used is nothing special.
#24: Re: 180 flywheel Author: Schumi, Location: Istanbul / TurkeyPosted: Thu Mar 28, 2013 3:41 am ---- Me and my friend will bought 3 set of light steel flywheel from TTV Racing.
#25: Re: 180 flywheel Author: Mangie, Posted: Thu Jul 03, 2014 8:28 am ---- Does a warped flywheel make any noise or vibrations that you fel inte the pedal. Does it mather if the clutch is pressed or not?
