Introducing the JHMotorsports Stage 1 B7-RS4 Supercharger Kit!!!

 

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.

Some clearancing of your vehicle is required to install the kit:

Finally, due to the location of the supercharger unit under passenger headlight in the front bumper, you will not be able to retain your OEM Passenger Side Fog Light. We include resistors in our kit to prevent the error light from showing up on the display on the dash.

 

OPTIONS

 

- Air Conditioning Line Modification and Core Charge: We modify 3 of the 4 AC lines on the car to allow for a clean, bolt-on installation. If you would like, we can ship you our JHM Stage 1 Supercharger Kit with modified AC lines for a core charge (see the dropdown below). Once you install the kit and ship your OEM lines back to us, we refund your core charge. If you do not want to incur this core charge, you can send your AC lines to us in advance for modification. Finally, if you plan on removing the AC system from your car entirely, we can omit these items from our kit and discount your price accordingly. Select your preference from the dropdown below.

FLASHING INFORMATION:

 *AS OF 1/23 B7 RS4 TUNING HAS MOVED TO OUR POWER-CONNECT FLASHING SERVER AND REQUIRES THE POWER-CONNECT SOFTWARE*

For Flashing Method, select "Flash Myself, SEPARATE POWER CONNECT Cable Purchase Required, CLICK LINK BELOW" if you're going to be buying a cable from us and flashing your car on your own. You'll need to add this option.

GO HERE FOR JHM POWER CONNECT CABLE

and add to your cart after adding the tune, just selecting the option is NOT enough. Make sure you have THOROUGHLY read through the instructions and are confident that you can set your computer up correctly. If you select this option for your tune, you must select a shipping method for your order so we can ship you a JHM Tuning-Flashing Cable. Please select a shipping method once you've added the tuning and the flashing cable to your cart. Instructions for installing the flashing software on your computer will be emailed to you after purchase.

 

If you already have a JHM POWER CONNECT Cable, select "I already have a JHM POWER CONNECT Cable." **NOTE: This is a proprietary cable with drivers specific to our Flashing Software so you must make sure that you have a JHM POWER CONNECT Cable, NOT just a generic USB Vag Com cable.** After receiving your paid order, we will send you an authorization form which we will use to create your JHM Tuning Flash Browser account and login information. This is the information you will use to access our server and flash your car with the JHM Tuning-Flashing Cable that you already have.

 

DISCLAIMER: JHM is now using proven flashing technology in order to get our tunes on our customers' cars in the quickest and most convenient way possible. You will be installing a proprietary JHM software that works ONLY with our flash cable (supplemental software such as Microsoft .net may be required). This program is what allows you to detect your ECU part number, fill in your information, select the correct program based on your hardware and then write JHM Tune to your ECU all through your OBD II port. Both of these programs are highly specific when it comes to configuring your computer to run them properly. While every effort has been made to clearly and completely explain this configuration in our instructions, the customer will ultimately be responsible for removing or disabling their own or third party anti-virus software or firewalls that will block the port required for you to log into our flashing server (see the link to our instructions below to determine whether or not this is something you'll be able to do). Basic technical support provided by JHM to help install these programs on your computer, diagnose programs with your computer, and/or internet connection may be subject to an hourly fee. Additionally, if something happens to your ECU during the flashing process, you should be able to restore it using our software. If you are still unable to make the ECU flash properly, you will be responsible for all costs associated with restoring your ECU and fixing the issue.

 

Requirements for Tune: 
- Windows computer with at least 1 USB (Universal Serial Bus) port 
- Wired Broadband Internet Connection (wireless can be unreliable) 
- JHM Tuning-Flashing Cable (Flash cable length cannot extend beyond 10 ft long unless a powered USB hub is installed in-line. 
- Battery Charger or equivalent power source capable of sustaining a 40 amp charge

 

You can download and view the instructions HERE to determine whether or not this is something you would like to do.
