    I have a 2nd gen supercharger from Magnuson. This pulley needed some material taken off from the bore to fit properly on the shaft.

    There is too much material on the back of the pulley for a proper fit on my supercharger. Upon seating, it contacts the snout as the design is different than what the stock pulley is
