The ProCharger 1GQ212-SCI High Output Intercooled Supercharger System is designed specifically for the 2008–2013 C6 Corvette equipped with the 6.2L LS3. Featuring a P-1SC-1 self-contained centrifugal supercharger, a C6-specific 3-core air-to-air intercooler, ProFlow bypass valve, 50 lb/hr fuel injectors, and a complete calibration, the system is engineered to deliver a substantial increase in power while maintaining excellent street manners and OEM-like reliability. The standard configuration operates at approximately 7 psi of boost and is designed to work with an otherwise stock LS3.

One of the major advantages of the 1GQ212-SCI is its straightforward, factory-friendly design. The self-contained supercharger requires no connection to the engine's oiling system, while the front-mounted air-to-air intercooler provides efficient charge-air cooling without requiring an aftermarket hood or major body modifications. The system retains the factory exhaust and is designed as a bolt-on installation, allowing the Corvette to maintain its clean, stock appearance while gaining approximately 45–50%+ horsepower over the naturally aspirated LS3.

The result is a powerful yet highly streetable C6 Corvette with significantly improved acceleration and a progressive power curve characteristic of a centrifugal supercharger. With proper installation, fuel, and calibration, the 1GQ212-SCI provides an excellent balance of performance, drivability, and reliability, making it an ideal forced-induction upgrade for owners looking to transform a stock LS3 into a substantially more powerful Corvette without sacrificing its everyday usability.

Bullet Bypass Valves Recommendations:

700 HP OR LESS

• ProFlow Valve: The ProFlow valve is the standard surge valve option for our street supercharger systems and kits. Compact in size, it can be fitted into tight spots when space is limited. Its butterfly valve is extremely durable and reliable, and this design creates a straight airflow path which acheives excellent flow for its size.
• Bullet Valve: This surge valve's compact design also makes it fit easily in tight spaces. It comes in both an open and closed format. The closed format allows you to recirculate air back into the system, or instead to run to an air filter to minimize noise.

701-1200 HP

• Race Valve: This is the industry leading surge valve for both street and race applications. The larger valve diameter is designed for high flow applications.

OPEN VS. CLOSED BYPASS VALVES

• Open - Vents to atmosphere and creates a distinctive “whoosh,” when the throttle blade suddenly closes, which a lot of people enjoy the sound.
• Closed - Vents to an external air filter or an internal tube for rerouting excess boost pressure back upstream of supercharger for a more quiet and subtle sound. More ideal for street applications where someone wants more of a silent or stealth operation of the supercharger.

For street applications, our complete systems and tuner kits come with the proper bypass valve based on the vehicle's horsepower output level so, no need to worry about the right one. However, ProCharger does offer upgrade options for their Systems and Tuner Kits with their Race bypass valve family for those seeking a little more sound or those that like the cool look of the anodized finish of their Race bypass valves.

Note: 2009-2013 models require water pump modification

Note: Race intercooler option requires oil cooler relocation
