ProCharger F-4X-136 Self-Contained Centrifugal Supercharger Head Unit with Splined Input Shaft & Threaded Volute - 3,200 HP - 4,200 CFM - 55 PSI Max Boost - Polished Finish - PC318A-136-C-SP-T-P
The ProCharger F-4X-136 Self-Contained Centrifugal Supercharger Head Unit sits at the top of ProCharger's self-contained race supercharger range. Engineered for elite motorsports applications, it can support up to 3,200 supercharged horsepower while delivering an extraordinary 4,200 CFM of airflow. Built for professional drag racing, radial racing, no-prep, offshore marine, land-speed, and other maximum-effort competition vehicles, the F-4X-136 is designed to satisfy the airflow requirements of today's most extreme engine combinations.
Capable of generating up to 55 PSI of boost, the F-4X-136 incorporates a splined input shaft and threaded volute for compatibility with professional crank-drive systems and race-oriented discharge plumbing. ProCharger lists the recommended motor base horsepower as CALL, allowing the head unit to be properly matched to highly specialized racing combinations.
Maximum-Airflow F-4X Platform
The F-4X-136 uses ProCharger's largest F-4X compressor package, including a 13.5-inch volute, 6-inch inlet hose connection, 5.35-inch inducer, 7.22-inch exducer, and a 4.5-inch outlet hose connection with a 4-inch outlet inside diameter. This massive compressor architecture is engineered to move exceptional volumes of air while maintaining the performance required in severe racing environments.
The splined input shaft is intended for dedicated race crank-drive systems, while the threaded volute provides a secure connection point for compatible professional discharge plumbing. These competition-specific features make the F-4X-136 an ideal choice for builders assembling uncompromising maximum-effort race vehicles.
Self-Contained Race Lubrication
The F-4X-136 features ProCharger's proven self-contained lubrication system, eliminating the need for engine oil feed and return plumbing. Its dedicated 6 oz. Race Oil capacity keeps supercharger lubrication separate from the engine's oiling system while reducing installation complexity and simplifying scheduled maintenance.
The compressor operates with a 4.77:1 internal step-up ratio and supports a maximum impeller speed of 72,000 RPM. This head unit is configured for standard rotation only, and reverse rotation is not available.
