Click-Here for more information on our 03 Cobra project carSTRATEGY

In keeping with our goal of providing our customers with the best possible value, we have tested a large group of components specifically designed for the 03-04 Mustang COBRA.

We have invested many hours evaluating and refining each of the Cobra products on our chassis “dyno", to ensure that we could develop as much power as possible, as safely as possible. End result is our now available "Dyno Tuned Options".

Our site menu on the left side of this page, lists the clear winners when it comes to “performance vs. dollar" value. Please check back often as we are always developing new ways to create more horsepower.


MOTOBLUE™ INTERCHANGABLE “QC” QUICK CHANGE BLOWER PULLEY SYSTEMS

One of the easiest ways to pump up the power of your supercharged Cobra is to increase the factory boost level with the award winning MOTOBLUE™ Interchangable "QC" Pulley System.

The MOTOBLUE™ Interchangeable “QC” Blower Pulley System for the Eaton supercharger. The factory Eaton blower pulley is pressed onto the shaft - which makes quick, trackside changes impossible. With the MOTOBLUE™ Interchangeable “QC” Blower Pulley Kit you simply replace the factory blower pulley with a precisely machined hub and attach your choice of pulleys with the 5 Allen head set screws provided.

Running a larger pulley on the street saves fuel, while the 2.75" bumps the boost for a very noticeable performance gain. Consider the time you'll save by installing this system Best of all you don’t pay the high price other manufactures are trying to charge for the same technology.

    MOTOBLUE™ "QC" BLOWER Pulley Kit Features:

  • CNC Machined 6061-T6 POLISHED Billet Aluminum Pulley.
    1. POLISHED billet 2.75 dia. produce up to 7 lbs. of additional boost with computer tuning

  • CNC Machined 4150 hardened STEEL Nitride Coated Hub Assembly

  • 5 Grade 8 Allen head bolts to secure the pulley of your choice
The MOTOBLUE "QC" BLOWER Pulley Kit is the "must have” replacement for all press-on aftermarket supercharger pulleys.

Installation time is around ˝ hour and will require a pulley puller/installation tool.

MOTOBLUE™ True Grip Auxiliary Idler Kits
Add Serious Horsepower to Your '03/04 Cobra With Our TRUE GRIP Auxiliary Idler Kit

 Made By MotoBlueRPM is proud to announce the introduction of the new MOTOBLUE™ GEN X Auxiliary Idler Kit for 03-04 Cobra.


Billet Auxiliary Idler Bracket (only)Don’t be fooled by the competition. We have shopped around and were shocked by what others are trying to pass off as “Auxiliary Idler Kits”. We actually came across one company that is selling an over–priced, poorly designed bracket with a low quality hi-drag stamped steel OEM idler pulleys as a “kit”.

The MOTOBLUE™ GEN X and also the origional GEN II TRUE GRIP Auxiliary Idler Kit are CNC from aircraft quality 6160 billet aluminum. CNC machined for a perfect fit featuring the highest quality “sealed for life” bearings. The same bearings that industrial supercharger manufactures use for high load extreme duty applications.

The MOTOBLUE™ TRUE GRIP Auxiliary Idler Kit is designed to wraps the blower belt over 88% around the compressor pulley, effectively eliminating belt slip at any rpm. The MOTOBLUE™ GEN X and also the origional GEN II kits are IN STOCK and available for same day shipping.
