ProCharger F-3R-112 (F-1X-12) Self-Contained Centrifugal Supercharger Head Unit with Splined Input Shaft & Threaded Volute - 2,100 HP - 2,300 CFM - 38 PSI Max Boost - Black Finish - PC314A-112R-B
The ProCharger F-3R-112 (F-1X-12) Self-Contained Centrifugal Supercharger Head Unit is engineered for professional motorsports and maximum-effort race combinations that require exceptional airflow, race-proven durability, and uncompromising performance. Rated to support up to 2,100 supercharged horsepower while delivering an impressive 2,300 CFM, the F-3R-112 is built for serious drag racing, no-prep, radial racing, marine, land-speed, and custom competition applications.
Capable of producing up to 38 PSI of boost, the F-3R-112 uses a large compressor package designed to move tremendous volumes of air while preserving the smooth, progressive power delivery associated with ProCharger centrifugal superchargers. ProCharger lists the motor base horsepower range for this model as CALL, allowing the head unit to be matched to highly specialized racing combinations.
Professional F-3R Race Configuration
The F-3R-112 is a race-focused F-3 configuration featuring a splined input shaft and threaded volute for compatibility with professional crank-drive systems and purpose-built race plumbing. These specialized features make the F-3R-112 well suited for builders who require the drive-system compatibility, durability, and installation flexibility demanded by elite competition vehicles.
The compressor incorporates a 12-inch volute, 5-inch inlet hose connection, 4.4-inch inducer, 6.75-inch exducer, and a 4-inch outlet hose connection with a 3.59-inch outlet inside diameter. This high-capacity compressor package is designed specifically for maximum-effort racing engines.
Self-Contained Race Lubrication
The F-3R-112 uses ProCharger's proven self-contained lubrication system, eliminating the need for engine oil feed and return plumbing. The head unit carries its own dedicated 6-ounce Race Oil capacity, reducing external plumbing while keeping routine supercharger maintenance separate from the engine's oiling system.
The compressor features a 5.63:1 internal step-up ratio, supports a maximum impeller speed of 72,000 RPM, and is available with a reverse-rotation option. This gives race builders greater flexibility when engineering custom crank-drive systems, bracket layouts, belt routing, and head-unit placement.
Built for Maximum-Effort Racing
Every ProCharger F-3R-112 is manufactured using premium materials, precision machining, and race-proven engineering. Premium bearings, precision-ground shafts, a rugged gear case, and an advanced high-flow compressor design work together to withstand the demands of today's highest-output competition engines.

Frequently Asked Questions
Why is the motor base horsepower range listed as "CALL"?
ProCharger specifies "CALL" for the motor base horsepower range because the F-3R-112 is intended for highly specialized maximum-effort race combinations. Compressor selection should be based on the complete engine package, operating RPM, airflow requirements, drive ratio, intended boost level, and racing goals.
Does the F-3R-112 require engine oil feed and return lines?
No. The F-3R-112 uses ProCharger's self-contained lubrication system with a dedicated 6-ounce Race Oil capacity, eliminating the need for engine oil feed and return plumbing.
Why Buy from Beefcake Racing?
