Metco Upper Supercharger Pulley - 2.70" (Hub & Ring)

2003-2004 Mustang Cobra

Replace the original 3.60" (Cobra) supercharger pulley with one of our overdrive pulleys to add boost to your Cobra.  The kit includes one pulley hub machined from high-grade steel that presses onto the blower shaft, and a CNC-machined aluminum ring bolts to the steel hub using the supplied stainless steel fasteners.  This two-piece design makes subsequent pulley ring changes a snap.

The steel hub is re-usable (unlike aluminum one-piece blower pulleys), and is black oxide-coated for long lasting surface protection.  The aluminum ring is hard-coat anodized in black to resist surface wear and corrosion.  Pulley rings are available separately in several sizes, including 2.70", 2.80", 2.90", and 3.00".   

Listed below are approximate boost gains that can be expected when installing these pulleys on a Mustang Cobra:

MUP2.70:  +5-6 lbs  MUP2.80:  +4-5 lbs  MUP2.90:  +3-4 lbs  MUP3.00:  +2-3 lbs

We recommend the use of our Auxiliary Idler Kit with these overdrive supercharger pulleys to maximize belt wrap and to minimize belt slippage.  These idler kits are available for the Cobra, and are listed elsewhere in this section.

Kit includes (1) supercharger pulley hub, (1) supercharger pulley ring, and hub-to-ring fasteners.
