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. The patented programmable i-1 design produces immediate response, even at low engine rpm, without any turbo lag or boost falloff at higher engine rpm. To further increase performance, competition mode can be quickly selected, and owners can use the touch screen to lock the supercharger in low ratio mode or select a personalized mode.
