Introducing the JHMotorsports Stage 1 B8-S5 4.2L Supercharger Kit!!!
NOW AVAILABLE FOR BOTH MANUAL AND TIPTRONIC (AUTOMATIC) TRANSMISSION S5s!
The JHM Stage 1 Supercharger is hands down the most cost effective supercharger solution for the B8-S5 4.2L. With common bolt-ons and supporting hardware, we have repeatably achieved high 11 second quarter mile runs, with 118MPH trap speeds!! With performance like that, your seemingly unsuspecting two door German coupe becomes a definite force to be reckoned with.

The JHM Stage 1 Supercharger Kit is the foundation for the different power levels that will be available for the B8-S5 4.2L. 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 B8-S5 4.2L will make 100-130 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 B8-S5 4.2L 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 S5.
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 S5, we upgraded the OEM belt and pulleys to a 6-rib system with our JHM 6-Rib Accessory Belt Conversion Kit. This Conversion Kit features 3 JHM Supercharger Kit specific pulleys including an Alternator Pulley, a precision balanced Crank Pulley, and a Supercharger Pulley good for 7 to 9 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 S5, 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.
Stage 2 is now available!
Here is an article from the Vortech Superchargers Blog regarding our kit for the B6-B7 S4 that uses the same Supercharger Unit! "JH Motorsports Uses Vortech Supercharged Boost to Rocket Their Audi S4 into the 11s..."

NOTE: Average installation time is 12-14 hours.
NOTE: Some clearancing of your vehicle is required to install the kit: Passenger frame rail mounting pad for bumper support bracket, bumper support bar on the back and core support. A pre-clearanced and reinforced passenger side bumper support bracket is included with this kit.

NOTE: We HIGHLY recommend new Coil Packs and Injectors (We stock both of these, go back one section to add them to your shopping cart) as well as performing a Carbon Cleaning during the installation of the supercharger for optimal performance. These cars are known to have Coil Pack and Injector failure once the vehicle gets over 60K Mile range. With FSI Engines, carbon buildup it is inevitable and if neglected too long can cause serious performance issues.

I drove up Pikes Peak over the weekend and the supercharger worked flawlessly. It was a very smooth drive all the way from Kansas City, Missouri to Colorado, up Pikes Peak and back to Kansas City again. You all definitely have a reliable supercharger kit. Just thought I'd share.
