    Welcome to Stiegemeier Porting Service

     Since 2003 Stiegemeier has been THE name synonymous with supercharger porting and modifications. With almost 4000 custom ports done to date, we are The Leaders in EATON Supercharger porting. And as one of the few EATON factory-authorized supercharger rebuilders, we are able to provide you with genuine EATON parts. Although we specialize in GT-500, Cobra & Lightning blowers and air-flow components, we are rapidly gaining respect for servicing Cadillac, Mini-Cooper, Jaguar, Roush, Saleen, Mercedes-Benz and others. In 2010, Stiegemeier announced that we now offer Injector Resizing, Flow Balancing, Sonic Cleaning, and rebuilding. We stock most all small parts available for your injectors. We also include a complete Flow Data Sheet showing the total flow of each injector at open and pulse flow. From our custom-built SXF-1000 air-flow supercharger test bench to our state-of-the-art DynoJet, we have the technology, resources, and expertise to give you the best your money can buy.

    And we guarantee more horsepower gain per dollar spent than any competitor!
