F-4X-140 ProCharger with spline and threaded volute

ATI’s self-contained (SC) ProCharger models are the first and only gear-driven centrifugal superchargers to feature self-lubrication, and contain the industry’s most advanced technology. In addition to the patented self-contained oiling design, SC ProChargers also feature the highest step-up ratio, exclusive billet impellers, and the industry's only billet gearcases for superior rigidity, sealing and appearance. These proven self-contained ProChargers were designed specifically for internal lubrication and have become the industry standard.
No competitor offers more winning choices than ProCharger. And ProCharger racers have won over 100 national championships in the past 15 years, something we are certainly proud of here at ProCharger. Built on years of racing success and R&D knowledge, the ProCharger line of superchargers produces the most power and increases your chances of winning.
No external lines or external pumps required – Our superchargers are the easiest to install, operate, and maintain. Our superchargers have an efficient internal oil / self-contained design so no hassles when it comes to racing.
