Industry Leading Power With ProCharger technology, reliably adding big horsepower to your engine is a lot easier than you may think. Intercooled ProCharger systems utilize exclusive features and proven technology to deliver reliable 50-85% gains in horsepower and torque with stock motors running pump gas. ProCharger technology is proven to produce the industry's largest power gains and coolest charge air temperatures, and ATI is also the only company that guarantees the best performance gains. Nothing else even comes close! For modified street applications, ProCharger technology delivers 10-second ET's with the least amount of engine modifications - and with the supercharger still under warranty. For highly modified applications, ProCharger is the undisputed leader, and is over 800 horsepower ahead of the competition. Superior products yield superior results. Advanced Design The patented SC design eliminates the need for oil lines and punching a hole in the oil pan. Additionally, instead of being forced to utilize heated engine oil or the grease in sealed bearings, SC ProChargers are lubricated with an extremely high quality synthetic oil which is specifically engineered for high speed use, and produces the least frictional heat and parasitic load. The self-contained design not only eliminates the heat that is transferred to a supercharger by engine oil in oil-fed applications, it also avoids the risk of clogged supercharger oil lines, oil drainage problems, or engine oil leakage. By combining an advanced multi-patented supercharger transmission design with the highest quality oil, SC ProChargers produce a larger net power gain because they run cooler and consume less power than comparable oil-fed designs. Both street and strip ProCharger models are also the most durable superchargers available, and are backed by the industry's best warranty coverage.
