Bolt On More Boost! VMP Performance's new 2.49 in. Pulley and 90mm Idler for the Roush M90 Supercharger allows you to squeeze even more power out of your blower with a simple bolt-on solution. This solution adds even more boost than aftermarket pulleys from Roush Performance, and it allows you to use your stock belt.

Steel Powdercoat Design. This VMP Pulley is constructed from solid steel and features a black powdercoat finish, providing lasting protection against rust and corrosion. Unlike aluminum pulleys, this steel pulley's finish won't come off thanks to the metal composition.

Installation. Installation requires basic hand tools and a little patience. VMP Performance created two options for this pulley solution based on your model year. Read below to learn the difference between 2005-2008 and 2008-2010 model pulleys. If you own a 2008 model, it's important to pick the right one.

Application. This VMP Performance 2.49 in. Roush M90 Pulley and 90mm Idler Package is designed to fit on any 2005-2010 Mustang GT equipped with a Roush M90 Supercharger.

Choosing The Right Pulley. For 2005 to early 2008 models, the M90 Supercharger features an older pulley set-up. If your M90 Supercharger has straight ribs, you own an older model. If your Supercharger features curved fins on top, you own a late model. Use this information to pick the right pulley option when adding to your shopping cart.

Is a tune required? and how much extra horsepower am i looking at?

  • A tune would not be required for this pulley and idler package. Horsepower can also vary depending on other components that are modified in your vehicle and what tune is currently being used.
