lighted flywheel
can someone post if they gain any hp going from a stock flywheel to a light weight one please :o

no hp gain, but the car accellerates faster

not a very safe practise.....

if lightening a stock flywheel then I agree.
I presumed the OP was talking about a proper aftermarket lighter flywheel, which are perfectly safe.

On an inertial dyno you will record a horsepower gain.

On other types of dynos you will not record a horsepower gain.

It depends on which type of dyno you use.

The main things is that with a proper aftermarket lightweight flywheel your car will rev much more freely. Allowing you to get up in revs quicker to reach the power you have, and a lightweight flywheel will facilitate heel-and-toe rev matching much easier.

A lightened flywheel frees up even more power in the lower gears since it is harder to begin momentum than it is to continue it.

Solving for 1st and 2ond gears, the lightened flywheel frees up 16.6 horsepower in 1st, and 5.9 horsepower in 2ond. Gains in the higher gears are negligible, about 1.7 horsepower in 4th and just over one horsepower in 5th." Author Sarah Forst
