ProCharger Adds Monster Power To 2004-06 LS1/LS2 Pontiac GTOs

Dearly departed Pontiac may be long gone, but the Aussie-based GTO lives on in enthusiasts’ hearts.  If you own a modern, down-under Tin Indian, and want to add more horsepower to the mix, ProCharger has just the ticket for you!

The HO Intercooled ProCharger system for LS2 and LS1-powered 2004-06 GTOs produces a 50-55% power gain on stock motors running pump gas, with 7 psi of intercooled boost. This compares to competing systems that produce 29-40% horsepower gains with the same 7 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 makers for the GTO. Additionally, with the coolest charge air temperatures available, the HO Intercooled ProCharger system for the GTO 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 a 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.

Tuner Kits:

The Intercooled Tuner Kit is identical to the complete system, but omits fuel injectors and a computer programmer. Higher boost and power levels are available for modified engines.
