    Default question about lightened flywheel..

    im readin about these and i read that it allows the engine to rev up quicker.. so whats the negative effect? would it wear the enigne more cause the parts have more momentum?and how much more wear?

    lightened flywheel = less weight = less momentum

    hmmm ic.. so what would be the negative effects of it? what if it was boosted? would it help turbo spool up faster?

    Well, for one thing, the car idles more rougher the lighter the flywheel is.

    more specifically, lightened flywheel = smaller rotating mass

    Simple Lighter flywheel = quicker rev's, however you do loose torque. As an example; Track racing with a Lightened flywheel is preferable as you do not usually see the low end of your rpm's. If you are drag racing it really depends on you engine power configuration. If you already have gobs of power<subjective> than It may yield better responsivness in the upper end. However if you have less than optimum power a lighter flywheel may be detrimental.
    Me, I'm dishonest. And a dishonest man you can always trust to be dishonest. Honestly. It's the honest ones you want to watch out for. Because you can never predict when their going to do something incredibly stupid.

    k fine then. Generally there should be no torque loss with a lightened flywheel, since you are freeing up rotating mass and that mass does not create torque.

    If you're drag racing you'll have to increase the RPM you launch from since the car launches off flywheel inertia. Less mass = Less inertia.
    Also keep in mind lightening the stock flywheel will weaken it, how much depends on how much it is lightened. If you've ever seen pics of what is left after a flywheel explosion you'd just bite the bullet and get an SSG or a Fidanza
