Blow Off Valve Adjustment:

The Blow Off Valve (BOV) is set to a neutral setting from the factory, its primary function is to bleed excess boost into the atmosphere to avoid compressor surge or (dead heading) the supercharger. Its secondary function is making throttle roll-off smoother, as you accelerate through the RPM band and boost curve you naturally roll off the throttle. By doing this you create vacuum which in turn opens the BOV and bleeds the boost away. Too soft a setting will give you a jumpy or rubber-bandy type of acceleration to hard a setting can jeopardize the blower. We recommend starting with a mid way setting, whereas four to five threads of the adjustment screw are showing.

To adjust the BOV you will need a 12mm wrench and a 6mm Allen wrench. Using the 12mm open end wrench unlock the locking nut by turning it counter clock wise, once loose spin it a few threads up to make room for adjustment. Using the 6mm Allen wrench bring it in or out according to your adjustments and needs.

Note, in higher elevation it may be necessary to start with a higher setting to begin with to help keep more boost charged up, never run a fully closed valve always leave a minimum of 2-3 threads showing. It’s important that during cruising speeds the BOV is venting to atmosphere, if you do not hear a sure of constant air bleeding off at highway speeds then your BOV is too tight and you risk Dead Heading the blower.

Boost Gauge:

A boost gauge is a good gauge to have to visually drive the added power; it helps to have a gauge so you can easily find the power when it’s needed. RIPP sells a wide variety of boost gauges, from digital to analog, when shopping for a gauge purchase one that references both boost and vacuum.

Note: A boost gauge should be installed in the Orange vacuum line feeding the BOV and MAP Sensor outline in the Vacuum Diagram on page 24. The vacuum/Boost reference should only come from the intake manifold after the throttle body.

RIPP GAUGE Pods for JK’s and other vehicles.

The JK is limited to space for on board instrumentation, we sourced out these gauge pods and think this is the easiest and best solution to the problem. These are very high quality units and are easy to install.

Snorkel Air Filter Box for River Raider Snorkel:

RIPP offers this rugged carbon fiber sealed air box and filter combination to mate to the River Raider Snorkel System. If water crossings are in your future its best to be safe and add this option to your system

RIVER Raider Snorkel Systems:

RIPP worked exclusively with River Raider Products to develop a perfect match for your supercharger kits. If water crossings are in your future this snorkel with our air box is the smart choice.

MBRP Exhaust:

RIPP has tested with a combination of nearly every exhaust system on the market. Most exhaust systems actually lost power. The cat back MBRP exhaust was the only exhaust to produce power from 1800rpm to red line. Most notably 6rear wheel HP through the midrange and a peak of 11 rear wheel HP at red line.

Hypertech Speedometer Calibrator:

If you're running non-stock tires, a Speedometer Calibrator corrects the speedometer and odometer for tires up to 54 inches. This device is engineered for the speedometer recalibration functions of the Max Energy Programmer, but without the additional expense of the other tuning features. The Speedometer Calibrator also comes with a USB cable and a CD containing software to enable quick updates and upgrades over the internet. ALL JK’s running larger tires will need this calibrator to correct the TRD issue.
