2003-2004 SVT Cobra Pulleys
It's a rare thing indeed to find a supercharged 2003 to 2004 SVT Cobra still rocking the factory blower pulley on its Eaton, and there's a very a good reason. Swapping out the stock pulley for a smaller version with higher boost was -- and to some extent still is -- a rite of passage for the Terminator Cobras and is one of the easiest and least expensive ways to make a ton of spare horsepower and torque. Supercharger pulleys from Billetflow and Steeda have much smaller diameters than stock which causes your Eaton's rotors to spin at a faster rate which increases boost pressure. If you've already invested in a supercharger pulley, then one of Metco's interchangeable crankshaft pulley rings might be right down your alley.
