 One of the easiest ways to pump up the power of your supercharged Cobra is to increase the factory boost level. This 2.80" blower pulley provides approximately 6 additional psi of boost, resulting in gains of up to 65 rear-wheel horsepower. It’s made from powder-coated cast iron for maximum durability and features extra-deep grooved ribs to eliminate belt slippage.
NOTE: Use with Supercharger Belt #M10005 and Installation Tool #M10003. Pulley/Tool Package (#M10004) also available. DiableSport II programmer (P/N M27000T) strongly recommended.
