I was looking at some light flywheels for my Audi S3. Does anyone have any experience with this? Are there any gains in hp or anything? There is one on Ebay which the seller claims gave him a 15 hp. Any toughts?

You could do a little research on My350z.com; they do lots of lightweight flywheels over there. It will free up some power by reducing rotational mass at the crank. The main effect is that the engine will climb through the revs much faster. Have to be careful, though, some are so light that it makes it more difficult to modulate your revs and reduces the streetability of the car.

Take a look at a product called fluidampr.

15hp = snakeoil.
