Lightweight flywheel without the noise?

jmlenz · 03-11-2010, 06:19 PM

hopefully some tuner out there develops a lightweight flywheel for the VHR that is not so light it doesnt absorb drivetrain NVH but is light enough to see some increased responsiveness and reduced weight.

I would think a lighter flywheel would reduce overall torque on the engine since you are reducing the the rotational mass.

What would be the benefit of a lighter flywheel?

Absolutely not true. It would reduce parasitic losses involved in the rotating the driveline (and in the other case a heavier flywheel). Ultimately it would actually improve tq and hp readings at the flywheel.

It will decrease inertia, which is not the same as torque.

^Yes you are correct, but who can make one that doesnt rattle and shake like an old VW beetle. That is the topic of the OP.

You can have your stock flywheel lightened as well if you want a less extreme set up.
