im starting to get a parts list together for my build. looking to get a new flywheel is one of them. was thinking of getting an aluminum f.w. for it being lighter. but would like to know if anyone has had bad luck with it tearing up clutches etc.., or should i just resurface mine

lighter flywheels give you a free rev but you also lose power as well. Not hugely noticeable but there is loss.

This is totally false.

There is no power loss from an aluminum flywheel. This has been proven in back-to-back dyno tests.


The friction surface of the flywheel will be made of steel, but the rest of it is aluminum. They are tremendously lighter than steel ones, (typically about 26 vs 9-12 lbs) and will rev up faster due to decreased rotating mass.

I've run aluminum flywheels before with no issues in daily driven cars.

i thought so. was just thinking how can you lose power when you spinning the motor faster. but that is why i made this thread. to get input. nubie thanks for input. paul thanks for input

Paul is it true the RPMs drop a lot faster between shifts with a lighter flywheel? That's one reason I didn't want one.

Your not building a race car, resurface the stock one and have fun.

I second that.

Less rotating mass equals less parasitic drain. This means more power is free to make it's way to the rear wheels.
I have an aluminum flywheel (weighed 13 lbs lighter than the stock one) and love it. The only thing I don't like is the quicker drop in RPM's when I let off the throttle. It makes it necessary to rev-match alittle more when down shifting.

I daily drove aluminum flywheel cars for years, and never experienced any negative effect from them at all. None. Zero.

That said, on a very mild combination, the money is certainly better spent elsewhere.

Paul.
