Up to 472 HP: Ford Performance Unveils Power Packs for 2015–2017 Mustang GT

With 435 horsepower onboard, Ford Mustang GT is not exactly a blubbering puddle of automotive grief. It is a fast, coupe or convertible with a sweet sounding V-8 that, in our testing, will be hitting 60 mph in as little as 4.3 seconds. That's all fine and good, but for those who should have more power and faster acceleration, Ford Performance has released a trio of "power packs" to kick the Mustang GT power up a notch (or three ). 2015-2017 Ford Mustang GT The first power pack kit, Power Pack 1, will be available next month and has a high flow air filter and a new engine calibration good for an extra 13 horsepower and 16 MW ft of torque.
