Underdrive Pulley thoughts

Thank you for posting that!

Well, I have met Mike at NST, and he did work on my last car, and I know he know's what he's doing. So I'd personally buy from him
As for 2.7hp per pound lost, that's complete horse shite... Maybe if you lose the 4 lbs AND you dyno between A/C on and A/C off, lol

I've researched these and the Unorthodox seem to be the lightest. On their site they say that each pound lost on pulley weight is equal to 2.7 HP. That would be about 10 HP. They didn't state how that is spread across the rpm band.
