ProCharger F-3R-102 Self-Contained Centrifugal Supercharger Head Unit with Splined Input Shaft and Threaded Volute - 1,600 HP - 2,000 CFM - 38 PSI Max Boost - Satin Finish - PC314A-102R
The ProCharger F-3R-102 Self-Contained Centrifugal Supercharger Head Unit is built for maximum-effort race combinations that require serious compressor capacity, professional-level drive compatibility, and dependable performance under demanding conditions. Rated to support up to 1,600 supercharged horsepower while flowing as much as 2,000 CFM, the F-3R-102 is engineered for drag racing, marine, land-speed, and other purpose-built competition applications.
Designed around engines producing approximately 375-550 naturally aspirated horsepower, the F-3R-102 is capable of generating up to 38 PSI of boost. Its centrifugal compressor builds boost progressively with engine RPM, helping provide controlled power delivery before supplying the high-RPM airflow required by serious race combinations.
Splined Input Shaft and Threaded Volute for Race Applications
This F-3R-102 configuration features a splined input shaft and threaded volute. The splined input shaft is intended for use with compatible race-oriented drive hardware, while the threaded volute provides a secure connection point for properly matched discharge components. These features make the F-3R-102 especially well suited for custom crank-drive systems and professional competition installations.
Because this head unit is designed around specialized race hardware, the complete drive system, brackets, pulleys, discharge connection, belt routing, and head-unit orientation must be engineered as a matched package. Verify compatibility with all supporting components before installation.
High-Flow F-3R Compressor Package
The F-3R-102 uses a large 12-inch volute, 6-inch inlet hose connection, 4-inch inducer, and 6.75-inch exducer. A 4.5-inch outlet hose connection with a 3.59-inch outlet inside diameter provides the discharge capacity required for its published 2,000 CFM airflow rating.
These dimensions give the F-3R-102 the airflow path needed for high-output race engines while distinguishing it from the smaller F-3D configurations. Proper compressor sizing should account for engine displacement, RPM range, volumetric efficiency, pulley ratio, intended boost level, and the complete intake and discharge system.
High-Speed Competition Performance
A 5.63:1 internal step-up ratio and maximum impeller speed of 72,000 RPM allow the F-3R-102 to reach the compressor speed required for its published airflow and horsepower capability. The drive system must be configured so the head unit remains within ProCharger's specified operating limits throughout the engine's RPM range.
The F-3R-102 is listed for standard rotation only. Reverse rotation is not available, so crank-drive layout, head-unit placement, pulley alignment, and belt routing must be designed around its standard rotational configuration.
Self-Contained Race-Oil Lubrication
The F-3R-102 uses 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 supercharger lubrication independent from the engine's oiling system while reducing external plumbing.
This listing is for the satin-finish ProCharger F-3R-102 head unit with splined input shaft and threaded volute. Crank-drive components, mounting brackets, pulleys, belts, intercoolers, discharge tubing, bypass valves, fuel-system components, tuning, and installation hardware are not included unless specifically stated elsewhere in the listing.

ProCharger rates F-3 superchargers based on maximum-effort race engines. Published figures are not absolute and may be higher depending on the specific application. Actual horsepower, airflow, and boost will vary with the engine combination, pulley ratio, crank drive, intercooling, fuel delivery, tuning, installation, and operating conditions.
Frequently Asked Questions
What distinguishes the ProCharger F-3R-102 from other F-3 head units?
The F-3R-102 combines a 1,600 HP rating and 2,000 CFM airflow capability with a splined input shaft, threaded volute, 12-inch housing, 6-inch inlet, and 4.5-inch outlet. It is configured for dedicated race-drive and discharge hardware rather than a typical street-oriented installation.
Does the F-3R-102 require engine oil lines or support reverse rotation?
No engine oil lines are required because the F-3R-102 uses a self-contained lubrication system with 6 ounces of Race Oil. Reverse rotation is not available, so the drive system and head-unit placement must be designed for standard rotation.
Why Buy from Beefcake Racing?
Matching an F-3R race supercharger to a maximum-effort engine requires careful planning around compressor airflow, engine output, crank-drive speed, pulley ratio, belt system, discharge hardware, intercooling, bypass capacity, fuel delivery, and tuning.
