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 Metco Interchangeable "QC" Pulley System.

The Metco Interchangeable "QC" Blower Pulley System for the Eaton supercharger. The factory Eaton blower pulley is pressed onto the shaft - which makes quick, track side changes impossible. With the Metco 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 Allen head set screws provided.

Running a larger pulley on the street saves fuel, while the 2.70" , 2.80" , 2.90" and 3.00" raise 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.
