The three kits add sharpen the Mustang GT and add GT350 equipment.
The Shelby GT350 Mustang is a seriously impressive performance machine, but some customers might not want to spend $56,495 for the coupe. Maybe these people already have the current Mustang GT and don’t feel like trading it in. Ford Performance will soon offer three Power Packs that will give GT owners some of the Shelby’s parts for a lot less money. After the upgrades, the engines will still be emissions-legal in all 50 states, but using 91-octane fuel will be mandatory.
Available for the 2015-2017 Mustang GT, all three kits include software updates that enable no-lift shifting and better throttle response. Power Pack 1 arrives in August for $539.00 with the improved code and a K&N air filter. The upgrades bring the 5.0-liter V8 to 448 horsepower and 416 pound-feet of torque, which is 13 hp and 16 lb-ft more than stock. Power Pack 2 comes in September for $949 and includes the GT350’s cold air intake with an 87mm throttle body. The tweaks take the V8 to 456 hp and 424 lb-ft. Finally, Power Pack 3 surfaces in October for $2,395 and gives buyers both the Shelby’s cold air intake and its intake manifold. Ford Performance says the engine would make 472 hp and 405 lb-ft after the improvements.
These upgrades can’t give the Mustang GT the unique sound of the 5.2-liter V8 with a flat-plane crank in the Shelby GT350, but more power and better throttle response are always welcome improvements.
