ProCharger F-4X-140-1 Self-Contained Centrifugal Supercharger Head Unit with Splined Input Shaft and Threaded Volute - 4,000 HP - 4,700 CFM - 65 PSI Max Boost - Polished Finish - PC318A-141-C-SP-T-P
The ProCharger F-4X-140-1 Self-Contained Centrifugal Supercharger Head Unit is engineered for professional racing programs that demand extreme airflow, massive horsepower capability, and purpose-built competition hardware. Rated to support up to 4,000 supercharged horsepower while moving as much as 4,700 CFM, the F-4X-140-1 is designed for maximum-effort drag racing, radial racing, no-prep, marine, land-speed, and other elite motorsports applications.
Capable of producing up to 65 PSI of boost, this F-4X configuration provides additional performance capacity beyond the standard F-4X-140. ProCharger lists the motor base horsepower range as CALL because selecting a supercharger at this level requires matching the head unit to the complete engine, crank-drive, pulley, fuel-system, intercooling, and tuning combination.
Extreme F-4X Compressor Capacity
The F-4X-140-1 uses a massive 14.5-inch volute, 6-inch inlet hose connection, 5.55-inch inducer, and 7.22-inch exducer. Its 5-inch outlet hose connection and 5-inch outlet inside diameter provide the discharge capacity required to support its published 4,700 CFM airflow rating.
Compared with the standard F-4X-140, the F-4X-140-1 increases published capability to 4,000 HP, 4,700 CFM, and 65 PSI. It is intended for highly developed race combinations that require greater compressor headroom and the supporting hardware needed to use that airflow effectively.
Splined Input Shaft and Threaded Volute
This F-4X-140-1 is equipped with a splined input shaft for compatible professional crank-drive systems and a threaded volute for race-oriented discharge plumbing. These purpose-built features provide the secure drive and outlet connections required in extreme competition environments.
Crank-drive ratio, pulley speed, belt alignment, bracket design, discharge plumbing, and supercharger placement must be engineered as one complete system. Compatibility should be confirmed before ordering or installation.
Self-Contained Race-Oil Lubrication
The F-4X-140-1 features ProCharger's self-contained lubrication system, eliminating the need for engine oil feed and return lines. Its published capacity is 6 ounces of Race Oil, keeping head-unit lubrication independent from the engine while reducing external oil plumbing.
A 4.77:1 internal step-up ratio and maximum impeller speed of 72,000 RPM allow the compressor to reach the operating speed required for its published airflow and horsepower capability. Reverse rotation is not available, so the installation must be designed around its standard-rotation configuration.
Built for Maximum-Effort Competition
The ProCharger F-4X-140-1 is intended for elite race combinations where every supporting component must be sized for extreme airflow and power. Engine construction, crank drive, fuel delivery, intercooling, bypass capacity, charge plumbing, engine management, and drivetrain components must all be selected to work with the complete combination.
This listing is for the polished ProCharger F-4X-140-1 head unit with splined input shaft and threaded volute. Mounting brackets, crank-drive components, pulleys, belts, intercoolers, charge tubing, bypass valves, fuel-system components, tuning, and installation hardware are not included unless specifically stated elsewhere in the listing.

Frequently Asked Questions
How does the F-4X-140-1 differ from the standard F-4X-140?
The F-4X-140-1 carries higher published ratings of 4,000 HP, 4,700 CFM, and 65 PSI. It also uses a 5.55-inch inducer and a 5-inch outlet with a 5-inch inside diameter, providing additional compressor and discharge capacity for more demanding race combinations.
Does the F-4X-140-1 require engine oil lines or support reverse rotation?
No engine oil lines are required because the F-4X-140-1 uses a self-contained lubrication system with 6 ounces of Race Oil. Reverse rotation is not available, so the crank drive and head-unit placement must be designed for standard rotation.
