    Default underdrive pulleys

    do they make much of a difference? i don't want to shell out the cash for them if they are not going to get much extra power out of them. i know its not going to be like a turbo or even a stroker, all i want is to not have to down shift going up hills as much. thoughts opinions?

    However, changing the pulley on a supercharger IS worth it.

    I think that a man with a helmet defending his country should make more money than a man with a helmet defending a football.

    It's a pretty minor improvement. Drag car yea, DD...not so much. With that kit, your low speed power steering is going to suffer and off road it will just suck.

    Downshifting up hills in kind of what you have to do. It's physics.
