ProCharger F-3R-136 Self-Contained Centrifugal Supercharger Head Unit with Splined Input Shaft & Threaded Volute - 3,000 HP - 4,000 CFM - 50 PSI Max Boost - Black Finish - PC314A-136-B
The ProCharger F-3R-136 Self-Contained Centrifugal Supercharger Head Unit stands among the highest-capacity self-contained centrifugal superchargers in the ProCharger lineup. Engineered exclusively for maximum-effort racing applications, it supports up to 3,000 supercharged horsepower while moving an incredible 4,000 CFM of airflow for demanding drag racing, radial racing, no-prep, offshore marine, land-speed, and custom competition builds.
Capable of generating up to 50 PSI of boost, the F-3R-136 is designed for professional racing programs where airflow capacity, durability, and dependable operation are critical. ProCharger lists the motor base horsepower recommendation for this model as CALL, allowing the head unit to be correctly matched to highly specialized engine combinations and racing applications.
Race-Ready F-3R Configuration
The F-3R-136 is equipped with a splined input shaft and threaded volute, making it well suited for dedicated crank-drive systems and professional race plumbing. These competition-focused features provide the drive compatibility, secure discharge connection, and installation flexibility required for today's highest-horsepower race vehicles.
The compressor uses a massive 12-inch volute, 5.75-inch inlet hose connection, 5.23-inch inducer, 7.22-inch exducer, and a 4-inch outlet hose connection with a 3.59-inch outlet inside diameter. This high-capacity airflow package is engineered to support the tremendous air volume demanded by extreme competition engines.
Self-Contained Race Lubrication
The F-3R-136 features ProCharger's proven self-contained lubrication system, eliminating the need for engine oil feed and return plumbing. Its dedicated 6-ounce Race Oil capacity reduces external plumbing while keeping supercharger lubrication and scheduled service independent from the engine's oiling system.
The compressor incorporates a 5.63:1 internal step-up ratio, supports a maximum impeller speed of 72,000 RPM, and is available with reverse rotation. This provides added flexibility when engineering custom race chassis, crank-drive configurations, bracket layouts, and belt routing.
Built for Maximum-Effort Competition
Every ProCharger F-3R-136 is manufactured with 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 provide the durability required for elite motorsports competition.

Frequently Asked Questions
Why is the motor base horsepower range listed as "CALL"?
ProCharger specifies "CALL" because the F-3R-136 is intended for highly specialized maximum-effort competition combinations. Proper supercharger selection depends on the complete engine package, operating RPM, crank-drive ratio, intended boost level, airflow requirements, and racing application.
Does the F-3R-136 require engine oil feed and return lines?
No. The F-3R-136 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.
