Bryan has an 07 Shelby GT manual (not a GT500). A Shelby GT is a Mustang GT with the 4.6L 3v engine that has the shelby package added, which consists of some handling, appearane, and performance mods. The package is installed at shelby and the vehicles sold through Ford dealers.
Bryan added the Shelby Paxton Air/Water Intercooled supercharger kit. The kit consists of a vortech/paxton head unit with a 3.6" pulley, larger injectors, mafia extender, second fuel pump to piggyback with stock pump, they supply a diablo predator with a tune for the kit. We went straight to a custom VMP X-Cal2 and then I dynotuned the vehicle.
Bryan was originally thinking about a smaller SC pulley but with power and torque numbers like this I see no reason to make that change. This is about the safe limit for a stock bottom end 4.6 3v.
