Bolt on 205-235 HP to a Stock Ford 5.0L 4V & GM LS3 Motors, with only 7.5 psi!! This latest addition to the ProCharger line 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. 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. Designed and manufactured in the USA, i-1 ProChargers feature exclusive billet impellers and rugged gear cases. Programmable boost is delivered by a highly durable variable ratio transmission design, with a rugged dry hybrid drive. Proven in over 4 years of intensive R&D and rigorous performance testing, the i-1 is available with ProCharger’s optional 3-year supercharger warranty. i-1 supercharger systems are 100% complete, and are backed by ProCharger and its network of dealers.
