Show original supplier description
The ProCharger 1GN302-SCI is a High Output Intercooled Tuner Kit specifically designed for the 2004-2006 Pontiac GTO, compatible with both LS1 and LS2 engines. This kit delivers significant power gains, estimated at 50-55% for stock motors running pump gas with 7 psi of intercooled boost. Key features of this ProCharger system include the P-1SC-1 self-contained supercharger, which eliminates the need for external oil lines, and a dedicated 8-rib drive system for reliable power transfer. The kit comes complete with a front-mounted air-to-air intercooler for optimal charge air cooling. The system also boasts an attractive, OEM-like appearance. This tuner kit is identical to the complete system but omits fuel injectors and a computer programmer, offering flexibility for those who already have or plan to source these components separately. Optional upgrades are available, including a D-1SC supercharger, helical gearset for noise reduction, a race blow-off valve, and a 1,300 HP GTO race intercooler upgrade (which may require minor modifications).
