  • VMP Performance 3.1" 8-rib bolt-on supercharger pulley
  • Black anodized finish 
  • Made in the USA 
  • Constructed of high-quality Billet aluminum 
  • Utilizes VMP’s 6-bolt hub pattern 
  • Fits 2003-2004 Cobra Mustang with VMP Supercharger
  • Also fits 2003-2004 Cobra Eaton blower with VMP's 6-bolt hub
  • As a general rule, 1 psi boost is equivalent to 3 mm or .1” in pulley size 
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. 

Any quoted boost numbers are based on VMP tuning. 

Includes: (1) 3.1" Bolt-on pulley
