NEW 2.49" design! approximately 1/2-3/4lb more boost than other pulleys.
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. The 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.
Tuning and complete packages available in the Roush Mods Section.
