You're searching the wrong forum...there was a discussion over there not too long ago.
Stock, the 3B FW was quotted as being 17.8lbs.

Thanks. I searched all AW. Maybe I should try FW instead of flywheel.

BTW, anyone here running an Aluminume flywheel? Thoughts?

No, I mean over there...the place you can't mention here.

Email me if that doesn't get you there.

Ive been runnin a 10.5lb aluminum fw from 2bennett for years, I give it two thumbs up. Quick reving, some additional noise/vibration from stock, but nothing major.

Just found a new Fidanza for $250. Should be here in a couple days.

034 Motorsport actually has a lightweight steel flywheel that's only a couple of pounds more than their aluminum one and it's supposed to be stronger and less noisy than the aluminum but still way less power robbing than stock. I believe its around 14 lbs and their alum. is 12 or somewhere in that ballpark. Please don't quote me on these weights but I spoke to Dan at 034 in person last week and he really likes this flywheel.
