Shelby GT500s love upgrades as evidenced by the powerful 2007 Mustang Shelby GT500 that Brenspeed upgraded using a TVS 2300 supercharger from the 2013 Shelby GT500 and a supporting cast of bolt-ons. A stock 2007 Mustang GT is nothing to scoff at, thanks to its venerable powerhouse 5.4-liter engine, but when you swap out the factory supercharger perched atop its intake for a larger more efficient unit to help it breathe, you really get some seriously impressive numbers out of it.
This kit, which BrenSpeed sells here, is compatible with any 2007-2012 Mustang Shelby GT500 5.4-liter engine. The company’s website explains that “the 2.3-liter TVS 2300 blower has a 33-percent larger inlet and a 68mm pulley sporting around 14 psi of boost!!” According to the numbers posted on its website, this $4,145.94 Brenspeed kit will net you between 700 and 750 flywheel horsepower on your 5.4-liter-powered Mustang.
