What point to go to billet flywheel?

[94-302-vert]

Ok, clutch time is darn near...

For the flywheel, Billet or nodular Iron?

At what HP or RPM limits should you not use a stock replacement flywheel?

Thanks!!!!

I believe the clutch will typically give out ahead of the flywheel...if you're using the HD or KC I assume that would be somewhere in the ballpark of 400bhp. So unless you're doing some heavy forced induction, the iron flywheel should be able to withstand the power. I never really saw the benefit of the billet flywheel when you could just move to aluminum for 60-70 dollars more. Somebody correct me if I'm wrong

if its lighter it might help you rev up faster

600+fwhp thats what DDperformance.com said IIRC. It was high before they recomended using something other the the ford flywheel. Since the Walshes are drivtrain specialist I listen when they speak. .02

I needed a new flywheel for my combo since its a 28oz balance. I went aluminum for the obvious benefits.

If you have the money go with a fidanza aluminum flywheel. They come with different weights so you can interchange it with different engine imbalances.

There isn't a hp # that tells you its time for a new flywheel.
