ProCharger F-4X-140 Self-Contained Centrifugal Supercharger Head Unit with Splined Input Shaft & Threaded Volute - 3,500 HP - 4,500 CFM - 60 PSI Max Boost - Polished Finish - PC318A-140-C-SP-T-P
The ProCharger F-4X-140 Self-Contained Centrifugal Supercharger Head Unit is built for the most demanding professional racing programs where maximum airflow, extreme boost capability, and uncompromising durability are required. Rated to support up to 3,500 supercharged horsepower while delivering an incredible 4,500 CFM of airflow, the F-4X-140 is engineered for elite drag racing, radial racing, no-prep, offshore marine, land-speed competition, and other maximum-effort motorsports applications.
Capable of producing up to 60 PSI of boost, the F-4X-140 combines ProCharger's proven self-contained design with a splined input shaft and threaded volute for compatibility with professional crank-drive systems and race plumbing. ProCharger specifies the motor base horsepower recommendation for this model as CALL, allowing the head unit to be correctly matched to highly specialized engine combinations.
Maximum-Airflow F-4X Platform
The F-4X-140 uses a massive 13.5-inch volute, 6-inch inlet hose connection, 5.47-inch inducer, 7.22-inch exducer, and a 4.5-inch outlet hose connection. The outlet features a 4-inch inside diameter, providing the airflow capacity required for extreme racing engines producing well beyond traditional four-digit horsepower.
The splined input shaft is designed for dedicated race crank-drive systems, while the threaded volute provides a secure connection for professional discharge plumbing. Together, these race-specific features deliver the durability, serviceability, and installation flexibility demanded by professional race teams.
Self-Contained Race Lubrication
The F-4X-140 uses ProCharger's proven self-contained lubrication system, eliminating the need for engine oil feed and return plumbing. A dedicated 6-ounce Race Oil capacity keeps lubrication independent from the engine while simplifying installation and scheduled maintenance.
The compressor operates with a 4.77:1 internal step-up ratio, supports a maximum impeller speed of 72,000 RPM, and is configured for standard rotation.
