At Midwest Turbo & Performance we know a thing or two about centrifugal superchargers. In fact, MTP owner Chris Spies spent several years on the ProCharger engineering staff, developing many of ProCharger's most popular superchargers and accessories. In addition to designing ProChargers, he also spent many years in the field helping racers get the most from their ProCharger. Now, just as then, Chris continues to provide his customers the support and know-how that puts racers at the front of the pack.
