2004 Pontiac GTO (LS1) ProCharger HO Intercooled System with P-1SC-1

When the GTO was reborn in 2004, Pontiac enthusiasts now had an LS-powered performance car to make up for the demise of the Firebird in 2002. Equipped with both the LS1 (2004) and LS2 (2005-06) engines, ProCharger once again led the way with air-to-air intercooled supercharger systems and tuner kits for these unique GM performance cars.

LS1 GTO

Utilizing 7 psi of intercooled boost, a ProCharger System for LS1-equipped GTOs produces a 50-55% power gain on otherwise stock engines running high quality pump gas. Built around the ProCharger P-1SC-1 supercharger and a dedicated, 8-rib drive, the system comes 100% complete, including the front-mounted, air-to-air intercooler, fuel injectors and a hand-held programmer.
