I would want to know how much hp would a lightweight crank pulley give me for a non turbo 94 3000gt. the only mod i have now is the injen intake system. I am talking about the stock size from 3sx.com, not the smaller one that is the underdrive pulley from unorthodox racing. Even being stock size, it weighs 5 lbs less. I know it will free hp and give it to the wheels, but about how much to the wheel and crank? Anyone with any info on pulleys please post glady appreciate it.

 

well it says on the site 10 to 15 hp and those people work on those cars all day everyday. so i imagine they know what they are talking about. they would have to.

 

I honestly doubt it will free up that much power...

Personally, I don't like the underdrive or lightweight pulleys because of the lack of dampening....but nearly everyone has a different opinion about that...
