MOTOBLUE™ CHEATER / "QC" PULLEY KITS

One of the easiest ways to pump up the power of your Shelby GT500 is to increase the factory boost level. When it comes to aftermarket pulley technology, there is no better choice than MOTOBLUE™. MOTOBLUE™ design engineers considered the engine's rpm capability, durability and other unique features to create the ultimate choice in aftermarket blower pullies.

MOTOBLUE™ offers 2 options for you to choose from: the MOTOBLUE™ Cheater pulley. and the classic Interchangeable “QC” Blower Pulley. the CHEATER pulley is rapidly becoming the pulley of choice. This simple replacement pulley gives the illusion of a factory stock diameter pulley to the untrained eye; but if you know cars, you will understand the powerful capabilities of this pulley. The MOTOBLUE™ Interchangeable “QC” Blower Pulley offers quick, trackside pulley changes.

The 2.60" CHEATER pulley bumps the boost to an impressive 15+ psi, and the 2.65" "QC" Blower Pulley bumps the boost to a comparable 12 psi. However, both pulleys do require custom tuning.

Installation is quite simple, but does require the use of a speical pulley puller and installation tool. With the correct tool it shouldn't take any more than an hour to complete.
