High Output Intercooled Supercharger-Producing the Largest Power Gains

The HO Intercooled ProCharger system for 2008-09 G8’s produces a 50-55% power gain on stock motors running pump gas, with 8 psi of intercooled boost. This compares to competing systems which produce 29-40% horsepower gains with the same 8 psi, but without ATI’s superior supercharger and intercooler technology.

This system installs in approximately half the time of other systems, with no need to punch a hole in the oil pan, replace the engine intake, or deal with all the complexity of an air-to-water-to-air intercooler. This new ProCharger system also has a much more attractive and “OEM” appearance than others for the G8. Additionally, with the coolest charge air temperatures available, the HO Intercooled ProCharger system for the G8 produces not only the industry’s undisputed largest power gains, but also the best engine longevity.

Standard equipment includes an exclusive air-to-air intercooler system and a patented self-contained P-1SC-1 supercharger, with 3-year warranty available. This new product utilizes the same proven technology as the industry-leading Intercooled ProCharger systems for LS1 F-bodies and C5 Corvettes.
