The ProCharger i-1 programmable supercharger produces not only the largest power gains, but also the ultimate performance curve. With an intelligent control system and an optional touch screen display, drivers can switch between 3 factory supplied performance modes, as well as a custom mode. Personalized display screens and data logging are also available. Building on the benefits of centrifugal design, the i-1 delivers higher compressor efficiency than screw blowers, utilizes the most effective intercooling, and avoids the heat transfer associated with engine-top mounting or an exhaust interface. Air-to-air intercooling is standard, and as experts agree, inherently provides better cooling and reliability than air-to-water intercoolers for street use. Due to these advantages, i-1 technology delivers the coolest charge air, the most power with greatest repeatability, and best in class fuel economy. Similar to P-1SC-1 and D-1SC supercharger systems, i-1 ProCharger systems produce far more power per psi of boost than air-water-intercooled positive displacement supercharger systems. Continuing the ProCharger tradition, i-1 supercharger systems also feature a broader operating range than PD blowers, and greater upgradability. The i-1 ProCharger is designed for both stock and modified applications, and supports up to 900 flywheel horsepower.
