    Underdrive pulley for supercharged beast

    Is this a good idea to install the underdrive pulley with the supercharged 9er or not??

    underdrive crank? it will slow down the blower.

    underdrive WP wont fit without crank

    underdrive alt - as long as there is a belt length that works, why not?

    I ment crank. It's a bad idea. Thank you.

    np.

    of course, if we could pulley down to regain that boost it wouldnt be bad. unfortunately, with a pulley that small (if they even make them) you woudl have NO traction.
