Magnum Powers is proud to announce our MPx 90 cubic inch supercharger. Which is now available to upgrade for either a Comptech or Jackson Racing M62 Supercharger Kit. The MPx 90 cubic inch supercharger is much larger in design and the features provide a better performance then the Eaton M62 or M90. The Supercharger Kit includes a high performance 90 cubic inch supercharger, intake plenum, manifold adapter plate and all required hardware to easily install. The supercharger kit is intended to upgrade existing Comptech or Jackson Racing supercharger kits or you can create your own kit by purchasing certain parts from Jackson Racing and the rest from Magnum Powers.
