Chevy SBC & BBC Procharger Cog Race Kit with F-3R 121 for Aftermarket EFI/Carb

There are many options available for ATI/Procharger kits, click the blue "Choose Product Options" button near the price to see them all. The standard kit is designed to be used with "V" belt alternator, water pump, and power steering front end accessories. You can add a mounting bracket for power steering as an option, or go with the Serpentine Accessory Drive option to install your remote P/S with or without A/C as well. That kit adds a 6 rib serpentine to run the accessories behind the cog supercharger drive. If you have a tight engine bay and want to be able to adjust the head unit location slightly there is a repositioning bracket, but then you will need to get a custom belt since the included belt will not fit.

ProCharger carbureted & aftermarket EFI superchargers were designed with one simple goal: blow the competition away. From 350 small blocks to 383 strokers and all the way up to massive 600+ cid big block monsters, ProCharger’s extensive lineup of applications for carbureted and aftermarket EFI Chevrolet engines are ideally suited for street, strip and full race vehicles. Building the correct engine and blower combination, numerous ProCharged “muscle car” owners have demonstrated that it is possible to build a 1,600+ horsepower street car, complete with air conditioning and power steering!

ProCharger’s carb and aftermarket EFI small and big block applications include a wide range of available superchargers, intercoolers, drive systems, bypass valves, carb bonnets and even serpentine accessory drives for both small- and big-block Chevrolet engines. From the custom designed 7075 billet aluminum impeller to the CNC machined transmission case to the industry-exclusive, compound bearing design, each self-contained ProCharger supercharger has been designed to deliver maximum performance, pass after pass, year after year, championship after championship.

Utilizing a patented high speed compound bearing design, these superchargers offer operating speeds unmatched by any other line of superchargers on the market. Lubricated with ProCharger’s own proprietary synthetic oil blend, the ultra-rigid precision ground 9310 steel shafts and gears (mounted on super-precision, high speed bearings) transfer power from the engine to a CNC machined 7075 aluminum billet impeller, spinning it at an overdrive ratio of 5.63:1–6.24:1.

Equipped with our 12” volute, these units pack a lot of power in a package that can be fitted under most hoods with little or no modification. Utilizing 6061 billet serpentine drive pulleys, these blowers are custom configured for your application at no extra cost. The mounting brackets, like the transmission case, are constructed from 6061 billet, providing a solid foundation for your ProCharger. The drive systems utilize 8mm or 14mm cog belts along with a rugged manual belt tensioner and oversized pulleys that provide maximum belt contact for peak power output.

This kit can be ordered with an intercooler, bypass valves and the tubing needed to boost your engine. F-3 ProChargers utilize advanced helixed impellers which accommodate a broad range of applications. With numerous trims available, our racer support staff can help you determine which F-3 model best suits your specific application.

Why choose ATI / Procharger Superchargers?
ProCharger supercharger systems are absolutely the most powerful and reliable supercharger systems available for your vehicle.

For street use or at the track, Intercooled ProCharger supercharger systems will deliver the largest increase in horsepower and torque available from any supercharger system. And thanks to the extremely low charge air temperatures provided by ProCharger technology, ProCharger systems also provide much better engine longevity by protecting your motor from detonation. ProCharger systems are designed with a fundamental understanding of the physics behind supercharging, and are engineered to the highest quality standards.

Superior Supercharger Technology
Thanks to relentless innovation, ProCharger technology is generations ahead of the competition.

The exclusive, patented, self-contained, gear-driven superchargers eliminate tapping into your oil pan, run cooler and produce more power than any competitor’s products. The impellers are created with aircraft grade 7075 T-6 aluminum alloy for tremendous strength and performance. The top tier material used in the construction of every ProCharger billet impeller and compressor housing allows the use of higher step up ratios than the competition. This in turn allows increased boost levels and superior overall performance than other offerings on the market.
