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