M122H Supercharger


The Eaton M122H Supercharger is the ultimate modern Roots supercharger. This supercharger is being used for our HMW M1 K.C. Supercharger Kit.



The largest commercially available Eaton Roots Supercharger, the M122H was used in – among others – the Ford Shelby GT500 with its 5.8 l modular V8 (not to be confused with the smaller M112). This is so far the biggest purely Roots based blower you can put under the hood of a BMW while the 6-cylinders are still present and boasting an amazing 2l displacement. Out of the box, this sees a bar of boost (14 PSI) with an intercooler! And this only utilizes just over half of its potential.
