ATIs self-contained (SC) ProCharger models are the first and only gear-driven centrifugal superchargers to feature self-lubrication, and contain the industrys 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.
The best-selling P-1SC-1 shares many of the design elements which deliver the record-setting durability and performance of ProCharger competition superchargers, and is also quiet and street legal. With their rugged design, these ProChargers are the only self-contained superchargers durable enough to be backed with a 3 year warranty and powerful enough to harness the benefits of intercooling.
The patented SC design eliminates the need for oil lines and punching a hole in the oil pan, thanks to an exclusive oil pump. This pump aerates the oil to create the oil mist lubrication required for the ProChargers precision bearings and gears. This oil pump (aeration pump) does not require priming at start-up, and oil changes are required only every 6,000 miles. Additionally, instead of being forced to utilize 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 also eliminates the heat that is transferred to a supercharger by engine oil in oil-fed applications, and avoids the risk of clogged supercharger oil lines, oil drainage problems, or engine oil leakage.
By combining advanced 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. SC ProChargers also feature an internal step-up ratio of 4.10:1 for improved belt tracking and traction, and maximum low-rpm boost and power.
ProCharger is also the first and only manufacturer to offer the choice of standard or helical gear set for noise reduction on the P-1SC-1 and the D-1SC supercharger models.
Its a simple fact of physics: cooler air makes more power. On street driven vehicles, air-to-air intercooling is a natural fit because it locates the intercooler at the front of the vehicle where it is exposed to a constant supply of cooling airflow. Experts agree that air-to-air inherently provides better cooling and reliability than air-to-water intercoolers for street use. Engineered with large-volume air plenums, ProChargers air-to-air intercoolers utilize a highly effective and extremely durable bar and plate intercooler core design that provides large surface areas for superior levels of heat dispersion.
Air-to-air intercooling is a highly effective one step process and represents a fundamental ProCharger advantage. Compressed air enters one side of the intercooler, making its way into the bar and plate core. Once in the core, the compressed air is cooled by the airflow moving through the passages or fins of the intercooler. Next, this cooler, denser air is routed into the throttle body and into the engine. ProCharger intercoolers typically feature best in class effectiveness of 70-80%.
On the other hand, air-to-water intercooler systems use a complex arrangement of intercooler cores, hoses, fittings, a coolant pump, electrical connections and yes, a secondary air-to-air heat exchanger. In street applications, an air-to-water intercooler is in fact an air-to-water-to-air system.
With air-to-water-to-air, heat is first removed from the air by the water circulating through the intercooler. This heated water is then pumped through a radiator, and returned to a tank. The overall system performance is watered down because its effectiveness is a diminishing function of the individual effectiveness of each heat exchanger. For example, 65% intercooler effectiveness and 60% radiator effectiveness produce a combined effectiveness of only 49%. Two step cooling is, by design, inherently less effective. Typically exposed to heat soak from the engine, air-to-water-to-air intercoolers are complex, difficult to install, and less reliable than air-to-air intercooling.
