Lightened flywheels

[efiniste]

Does anyone know of any drawbacks/safety issues with using an aluminium flywheel? I seem to remember reading they shouldn\'t be used somewhere but I can\'t remember where!

Also, anyone know of suppliers/prices in the UK (for a third gen)?

thanks,

Steve

i wouldnt have said there are safety issues but youll expeariance the car loosing momentum going up hills and with quick get aways youll have more chance of bogging down the engine. you would be better off with a light weight steel one from racing beat. imo

I cant remember if I read it somewhere, or was told by a friend about alloy flywheels going bang when the reach the limit. The limit I understand to be lower than steel units.

I had a race weight flywheel fitted to the scoob, and it caused lumpy idling until the ECU was re-mapped to compensate for it.

That was made from Chrome-molybdenum steel tho.

Hi Steve,

I would have though an Alloy flywheel is a bit extreme if it\'s for a road car especially as the steel ones are super light compared to the stock flywheel .

As for drawbacks l raced with someone who used an Alloy flywheel a few years ago and by the end of a race due to expansion had real problems with clutch disengagement ! this would be have been horrendous on the road.

Hope this helps.

Thanks for the feedback guys. I\'ll let you know what I decide on. There doesnt seem to be much in it as far as weight is concerned. The ones I\'m looking at are between 9.5 and 12 pounds.
