JHM Supercharger Kit (Stage 1) for the B7-RS4 is NOW AVAILABLE!!
The JHM Stage 1 Supercharger is hands down the most cost effective supercharger solution for the B7-RS4. With common bolt-ons and supporting hardware, we have repeatably achieved mid to high 11 second quarter mile runs, with 117-118MPH trap speeds!! With performance like that, your seemingly unsuspecting four-door German sedan becomes a definite force to be reckoned with.
The JHM Stage 1 Supercharger Kit is the foundation for the different power levels available for the B7-RS4. With the addition of a smaller pulley, an intercooler, fueling upgrades, or even a built motor along with our software upgrade, you can build off of the Stage 1 kit to meet your power output needs. This Stage 1 Kit features the same supercharger head unit that was on our in-house, record setting 2007 B7-RS4 4.2L FSI that ran an incredible 10.7 second quarter mile at 130 mph. That was at full weight, a complete interior, a complete exhaust system, and street tires!
FEATURES AND SPECIFICATIONS
Our JHM Stage 1 Supercharger Kit for the B7-RS4 will make 80 to 100 wheel horsepower (WHP) over your car's current configuration. Your current modifications, the dynamometer (dyno) used, temperature, elevation, and octane of gas will all effect the exact amount of power gains.
Our Supercharger Kit features a Vortech V3 Si Centrifugal Supercharger Head Unit that is good for up to 800 horsepower! (Unchecked, this amount of power would be too much for a stock RS4 motor. Through our extensive development and testing process, we were able to limit the output of the supercharger to levels safe for the stock motor through hardware and tuning.) The V3 Si blower is a self-contained unit featuring quiet, helical cut gears. The only time you hear noise from the blower is at idle and low speeds. At wide open throttle, you hear nothing but the raw power coming from your JHM Supercharged RS4.
The JHM Stage 1 Supercharger Kit also includes our JHM Supercharger Mounting Brackets that were designed and are made in-house. These brackets are made from reinforced steel, laser cut, and then powder coated black for a clean installation.
In order to insure the longevity and durability of the belt and pulleys on the RS4, we upgraded the OEM belt and pulleys to a 6-rib system with our JHM 6-Rib Accessory Belt Conversion Kit which includes our Automatic Tensioner Upgrade. This Conversion Kit features 3 JHM Supercharger Kit specific pulleys including an Alternator Pulley, a precision zero-balanced Crank Pulley, and a Supercharger Pulley good for 5 to 7 pounds of boost (exact boost levels will vary depending on your exhaust system, other modifications, and environmental factors).
Due to the compact engine bay of the V8 RS4, we had to locate the Vortech Supercharger Head Unit off of the passenger side of the motor, below the headlight. We created a number of different proprietary parts including our JHM Supercharger Kit Silicone Inlet and Outlet Hoses. The Inlet Hose is made from reinforced silicone to prevent collapse under vacuum. The air intake is filtered through a JHM Supercharger Kit specific K&N high-flow, conical air filter.
We are currently working on JHM Supercharger Kit add-ons that will allow you to use more of the supercharger's power capabilities. Stage 1+ (Intercooled with upgraded fueling and a smaller pulley, safe for stock motors) should be available in Spring of 2016. Stage 2 will require a built motor for engine safety and longevity. Please contact us for more information regarding Stages 1+ and 2 as well as a JHM Built Motor for your B7-RS4.
