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 - Satin Finish - PC314A-136
The ProCharger F-3R-136 Self-Contained Centrifugal Supercharger Head Unit represents one of the highest-capacity self-contained centrifugal superchargers in the ProCharger lineup. Designed exclusively for maximum-effort racing applications, it supports up to 3,000 supercharged horsepower while delivering an incredible 4,000 CFM of airflow for the most demanding drag racing, radial racing, no-prep, offshore marine, land-speed, and custom competition builds.
Capable of producing up to 50 PSI of boost, the F-3R-136 is engineered for professional racing programs where airflow, durability, and reliability are critical. ProCharger lists the motor base horsepower recommendation for this model as CALL, allowing the head unit to be properly matched to highly specialized engine combinations.
Race-Ready F-3R Configuration
The F-3R-136 features a splined input shaft and threaded volute, making it ideal for dedicated crank-drive systems and professional race plumbing. These features provide the durability and flexibility required for today's highest-horsepower competition vehicles.
The compressor utilizes 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 airflow package is engineered to support the tremendous volume of air required by extreme competition engines.
Self-Contained Race Lubrication
The F-3R-136 utilizes ProCharger's proven self-contained lubrication system, eliminating the need for engine oil feed and return plumbing. A dedicated 6-ounce Race Oil capacity simplifies installation while keeping supercharger lubrication independent from the engine's oiling system.
The compressor uses a 5.63:1 internal step-up ratio, supports a maximum impeller speed of 72,000 RPM, and is available with reverse rotation, providing flexibility for custom race chassis and crank-drive layouts.
Built for Maximum-Effort Competition
Every ProCharger F-3R-136 is manufactured using premium materials, precision machining, and race-proven engineering. Premium bearings, precision-ground shafts, a rugged gear case, and an advanced compressor design deliver the durability required for elite motorsports competition.
