More Boost for More Power. Are you a Shelby GT500 owner who is on a quest to add even more tire shredding power to the rear wheels of your mighty serpent? If so, did you know that a reduction of just 0.125" in your supercharger pulley's diameter will yield about a 1 PSI increase in boost? Well now you can increase the boost of your GT500 by 3-4 PSI, when compared to the stock 3" pulley, just by installing a VMP Tuning 2.50" Stock Look Supercharger Pulley.

High Quality Construction. VMP Tuning manufactures their Stock Look Pulley to OEM specifications from high-grade steel for strength and durability. Featuring a precision machined center bore this VMP pulley press fits in place just like factory pulley. VMP then completes their pulley in a black powder coated finish, which is identical to the original, so no one will ever notice your hidden performance upgrade.

Required Upgrade. For proper operation and maximum power potential this VMP 2.5" Supercharger Pulley will require reprogramming the vehicles computer. AmericanMuscle recommends a custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Application. This VMP Tuning Stock Look 2.50" Supercharger Pulley is specifically designed for use on the 2007 to 2012 Shelby GT500 Mustangs equipped with the stock 2.1L Eaton supercharger.

With this pulley for my 2012 gt500 would I need a aux idler pulley kit

  • The VMP Stock Look Supercharger Pulley will not require an idler pulley kit.

I have the Metco 2.6" bolt on pulley, how much more boost will the 2.5 give over the 2.6? And is a re-tune necessary?

05GTHI

  • You are looking to get probably another psi/lb of boost by going to the 2.5" and it will still require a tune once installed

Will this vmp pulley be compatiable with the metco aux idler kit?

MO

  • Unfortunately, we have not test fitted compatibility between VMP Stock Look Supercharger Pulley and the Metco Aux Idler kit, so we would be unable to confirm fitment at this time.

What else other than a tune do you need to install this pulley? New idler pulley?? Colder plugs??

07beachGT

  • The VMP Stock Look Supercharger Pulley - 2.5 in. (07-12 GT500) will only need a updated tune to install. A idler puller would be ideal however not needed.

    Love it!

    I replaced my VMP 2.8 supercharger pulley with this 2.5 about a month ago and can immediately feel the difference in boost. I can also hear that beautiful supercharger whine as I punch it! Only negative I have is I wish it was more clear to buy the special tool to remove the old pulley and add the new one. Be cause i didn’t have the proper tool I damaged my old pulley trying to use a universal tool (my fault, not American Muscle). I ended up having to take my Shelby to the shop to have a professional put my new one on. Given I had the right tool and the patience to order it, probably would have taken about an hour to work on. Because i didn’t have the tool it took the mechanic about 3 hours to replace the pulley and thats only because he had to build the tool.
