SLP Supercharger Pulley, 2007-08 Mustang GT 500 (2.70).
One of the easiest ways to pump up the power of your supercharged 2007-08 Mustang Shelby GT 500 is to increase the factory boost level. SLP''s 2.70 blower pulley provides approximately 3 additional psi of boost, resulting in gains of up to 35 rear-wheel horsepower, but not at the cost of reliability or durability. It''s made from powder-coated ductile iron for maximum durability and features extra-deep grooved ribs to eliminate belt slippage. Retains use of the factory serpentine belt.
NOTE: SLP STRONGLY recommends use of DiabloSport II programmer Part# M27050T. *Also recommended is Part #M10012 Supercharger Pulley tool package for proper installation of pulley (conventional 3-plung pullers will not work). |
