ProCharger supercharger systems are produced from the finest materials available. All castings are poured from "virgin" 356 aluminum alloy and heat-treated to a T-6 hardness before CNC machining. ATI's exclusive billet impellers are machined from 7075 T-6 aircraft aluminum, while the super precision bearings used in all ProCharger models are made in the USA, and are of a consistently higher quality and speed/load rating than those used by any of our competitors. In fact, ProCharger superchargers are so reliable that they are used as standard equipment by many leading boat manufacturers in the extremely demanding marine environment. ATI is the only centrifugal supercharger which can be ordered as OEM equipment from any performance boat manufacturer.
