2003, 2004 SVT Cobra 4V 4.6L
Metco Interchangeable Crank Pulley Kit
One of the best ways to get the most power out of your Cobra's supercharged engine is to increase the amount of boost pressure your Eaton M112 supercharger is pumping into your cylinders. One of the easiest ways to do that is with this Metco crank pulley kit. This kit replaces your extremely heavy factory crankshaft pulley with a high-quality hub that's able to mount any of Metco's interchangeable pulley rings to make as much extra boost as you need at the track, before swapping it out for the drive home. These rings can swapped out in only a few minutes and come in a variety of sizes that can make up to 10 extra pounds of boost pressure. This kit only fits 2003 to 2004 SVT Terminator Cobras.
The kit comes with an idler pulley relocation bracket and a tool for pulling out the crank pulley. The kit can be installed with no drilling, cutting or other permanent modifications, allowing you to swap back to the stock pulley if you really need to. The kit comes with a single interchangeable pulley ring in your choice of size, options for which are available from our drop-down menu. Some pulleys will require custom tuning.
Metco's pulley rings are also sold separately.
Pulley size and custom tuning:
Pulleys with 4psi or greater boost will require custom tuning. We recommend taking advantage of Stage 3's custom tuning package that comes with SCT's X-Calibrator 3 handheld tuner and qualifies you for our Loyalty Tunes program.
