  • Description
  • Reviews
This 6-rib 2.49" pulley is a very popular upgrade for owners of new Mustangs equipped with Roush M-90 Superchargers who wish to add more boost. This is a bolt on style and not the press on style found on most 2009 and 2010 Roush supercharged Mustangs. This is an easy way to add another 3 to 4 psi of boost over stock.

The pulley is CNC-machined from high-grade steel for precision fit and extreme durability, and the surface is black oxide-coated to prevent rust. The pulley is keyed and installs as a direct replacement for the original Roush supercharger pulley.

It is recommended to replace the factory idler pulley located directly beneath the supercharger pulley with a Metco Motorsports billet idler pulley, PN MIP-90 .

Ordered the cold air and tuner combo. Best tune I have had. Really woke up my 5.0
