wondering if anyone is considering doing this. Don't know if it is legit.

TVT posted some info on this recently but has anyone seen any dyno sheets to back up the claims yet?

No, its an underdrive pulley, 230 one is an overdrive.
Best to ask the vender for there report on the product 1st.

It is not an underdrive pulley or an overdrive pulley. It is a lightweight crank pulley with the same dimensions as stock. They are produced by adedin motorsports.

Typical gains on a stock 3.2L are 10-12 HP.

well... the ad in the link says Underdrive pulley

would you be able to put on the lightweight underdrive pulley with the lightweight crank pulley? What gains could you see with both of them?

You're missing the point, there is only one pulley, and it's the crank pulley.

Seems hard to believe that changing out only that one pulley can yield that kind of horsepower gain.
You have to be losing something somewhere else, maybe not turning the alternator and water pump fast enough to do what they were designed to do under all conditions?
