Magnum Powers has the answer with our new Idler Bracket that increased belt wrap around the blower pulley by 45 degrees.

The Magnum Powers Idler Bracket that replaces your original is pictured below with its adjustable third idler post.

The top post can be adjusted up close up under the supercharger pulley for maximum wrap and can accommodate blower pulleys of various diameters.

The Idler Bracket is shown installed with three 90mm Idler wheels demonstrating the increased belt wrap, an increase of 45 to 50 degrees. The Idler Bracket is compatible with the stock Eaton, Magnum Powers or other aftermarket superchargers and either stock or aftermarket 90mm idlers.

Expect 7rwhp to 30rwhp improvement depending on how much your belt is slipping.
