Oh my. Take one Shelby GT500 supercar ( I know, you’re gonna say pony car, but 500 HP is a supercar in my book, so get over it ) , throw on a stage 3 kit from Roush and BLAM that’s 700 HP. The kit includes a cold air kit, Roush supercharger, and all kinds of extra goodies including a new set of pullies. As if I needed to say it, installing the stage 3 kit does void your factory warranty. But who cares – you’ve got 700 HP under your right foot! Via Autoblog.
Shelby GT500 + Roushcharger = 700 HP
