You can go from mild to wild with your VMP supercharged '03-'04 Cobra with VMP's line of supercharger pulleys. Upgrading your stock pulley to a smaller VMP supercharger pulley, you can increase boost levels and get more from your supercharged setup.
The VMP 3.1" pulley will give you an average boost level of 15-16 psi with a stock lower.
VMP's pulley line-up for the 2003-2004 Cobra is constructed from high quality billet aluminum for durability. Black anodization helps prevent corrosion and minimizes wear.
When changing to a smaller pulley from stock, to maximize belt wrap and minimize belt slippage, an Auxiliary Idler Kit is recommended to reduce belt slack.
