NEW 2.49" design! approximately 1/2-3/4lb more boost than other pulleys.

Includes larger 90MM replacement idler to improve belt wrap and take up slack, allowing for use of stock belt.

Roushcharged M90 Blower Pulley for 2008+ Mustang 4.6L 3V with Roush Blower.

For late 2008/2009 Roush changed the type of pulley on their Stage 3 cars and M90 Roushcharger blowers, VMP now offers a pulley that fits! The old pulley was a keyed type held on by a bolt, these blowers can be identified by their straight ribs on the top. Thew new blowers use a press fit pulley with no bolt and a plastic plugs in the front, these blowers have curved fins on top. The new style pulley requires a special tool to remove and install the pulley available here.

Adds even more boost than the aftermarket pulleys from Roush Performance.

Tuning recommended when swapping from a stock pulley. Most tunes will adjust if swapping from a 2.55 or 2.57 pulley.

One piece steel design powdercoated so it will not rust. Will not come off like some aluminum pulleys.
