Hi guys im thinking about getting my flywheel machined out at the back and lightened up in my car, just wondering if anyones done this to a standard/aftermarket flywheel and what kind of a difference has it made? I'll be getting an exedy sports tuff clutch fitted up soon with a single mass flywheel, but before i put it all in i was thinking of getting them to machine the flywheel down and lighten it. It works for me in theory, but in practice, is it worth it? Al
By machining your fly wheel, your reducing the rotating mass of your engine. That mass in turn helps to maintain torque. Reducing that mass on a race car( which revs constantly in the high range 4500+ rpm ) isnt an issue, but in a street car, where the rpm rise and falls, would make it an absolute pig to drive.
Mate that is just plain wrong. A Lightened flywheel does not reduce torque. The one negative of a lighter flywheel is that it makes taking off from a stop more difficult as there's less inertia. Otherwise, nothing but benefits as it 'frees' up power by reducing inertia and weight, makes rev-matching/downshifting easier as the engine revs more freely.
Yeah thats what i thought through some research on the topic, figuring itll be a little harder to take off (nothing a few revs cant fix) but itll take the weight off the motor and rev up more freely and quicker. Also being a cammed motor its likes to rev up a little anyway, so i think it should benefit it a little One thing though i was thinking, its running a 3.89 diff atm, would this affect it at all? Being all rev and no go?? Keep the thoughts coming guys! I like hearing what u all have to say on the matter!
if you've got a diff with 3.89 i reckon that would help cancel out the loss of torque from the lightened flywheel
