ProCharger Race and Championship-Winning Technology for late-model HEMI engines
Building on our late-model, EFI HEMI supercharging leadership, and combining it with our 100+ international racing championships, ProCharger now has taken the next step: the Reverse Cog Race Kit for late-model, modern 5.7L and 6.1L HEMI engines. Designed specifically for custom, ultra-high horsepower racing applications, the new Reverse Cog Race Kit features a low-mount ProCharger F-1A, F-1C or F-1R supercharger and proven 50 mm cog drive and tensioner design. The Reverse Cog Race Kit can be used in both intercooled and non-intercooled applications.
This kit is NOT designed for stock engines or stock vehicles and will require custom intercooler tubing, front fascia modification, fuel system upgrades and custom tuning.
F-Series Supercharger Models Made in the USA!
These record-setting, self-contained ProCharger models feature a patented, high-speed compound bearing design and provide operating speeds unmatched by any other supercharger on the market. ProCharger F-Series superchargers are the ultimate for today’s ultra-high horsepower street, strip and extreme racing applications.
Why ProCharger Superchargers for your HEMI powered Car or Truck?
ProCharger superchargers offer some of the most reliable, and efficient supercharges on the market today. Think of a turbo without the lag. Like turbos, ProChargers utilize centrifugal forces to compress air, but unlike turbos they are driven by the engine’s crankshaft not its exhaust flow. The result is a liner, predictable power curve, with very streetable manners. Another advantage is ProChargers are able to maintain much cooler intake air temperatures. Because the system’s intercooler has greater flexibility in mounting locations, engineers are able to optimize the charge cooling system. In many cases ProCharger’s massive 3 core intercooler is mounted ahead of the radiator, directly in the cool air stream at the front of the vehicle. Lower intake air temperatures translate into a denser air charge, and reduce the engine’s exposure to damaging detonation.
A centrifugal supercharger works by combining the function of several components; including impeller, compressor housing, diffuser, and transmission. As in a turbo, the impeller is a turbine wheel that pushes air into the compressor housing at high velocity. It’s a small part that has a big job. It rotates at extremely high RPM and endures massive mechanical and thermal loads. It must be carefully engineered, precision crafted and balanced to hundredths of a gram. The compressor housing (volute) is the snail-shell shaped casting that functions as a collector, it gathers the air flow and delivers it to a downstream pipe. The diffuser’s job is to convert the kinetic energy of the air flow (velocity) into pressure (boost). This is accomplished by gradually slowing the speed of the air charge, allowing the air “behind” it to “catch up” thereby building pressure in the gas column. The transmission is the gear-set and bearings that support the impeller and multiply the input (crankshaft) RPM to the impeller. The impeller needs to turn at very high RPM to be effective. Typically, the impeller shaft is overdriven by a factor of 5.4 but can be as high as a factor of 8. So if the engine is turning at 1,000 RPM the impeller is turning at 8,000 RPM, if the engine is turning at 6,200 RPM the impeller is turning at 49,600 RPM!

Stage II HEMI Supercharger Kit
ProCharger’s stage II race ready kit features an independent drive system. This system separates the supercharger’s head unit from the serpentine belt, and places it on its own pulley. The Stage II kit is intended for modified HEMI engines but works well with factory modifications as well.

A2Speed’s GEN III HEMI BackgroundMany of us at A2Speed have been working on the Gen III since its inception. As a team we are immersed in the Hemi world. We own, drive, modify, race and occasionally…break them. We use this experience to create SOLUTIONS, not just parts. Automotive engineering has advanced such that it is often difficult to improve on the work done by the OEMs. Difficult, not impossible. Utilizing advanced 3D modeling, CFD and stress simulations coupled with rapid prototyping, allow for the development of specialized parts that would be impractical at OEM volumes. Solutions validated with real world testing. Craftsmen level quality; and because we don’t have the layered overhead, our prices are often at or below the OEM price.
Advanced Aerospace Grade MachiningProduction manufacturing is performed by partner companies that have proven track records for quality and timely deliveries. We look for certifications such as ISO-9001 and AS-9100 along with ITAR and GIDEP registrations. Several of the companies we work with regularly supply major aerospace firms and the DOD. Why use outside machining services? So that you get a better part at a better price. By utilizing only the machine cycles we need, and leveraging the superior skills and years of experience, A2Speed can give you exceptional quality at truly affordable prices.
