For sale Magnuson MagnaCharger MP90 4th generation supercharger, part #10-90-41-013. It was engineered for 3.0-5.7 liter port injected engines. The Magnuson MP90 supercharger was designed as a compact, flexible supercharger for increased power with original equipment quietness and reliability without adversely affecting fuel economy. The supercharger is in brand new condition, was installed, then removed when the customer changed his mind and canceled the order. Supercharger has a Black surface finish, 8.850" nose drive and 6 rib 2.20 pulley. I have two of these which I purchased from Magnuson Performance. Asking price for each supercharger is $280 shipped OBO to lower 48 states.
