You bought the Ford Mustang GT. Fun car, that one. When you go to sleep at night, though, your dreams are filled with visions of snake badging, noises from a flat-plane crank V-8, and a desire to hit the racetrack. You're not a crazy person, you just wish you could afford the Shelby GT350. We all do. It's a wild rip-snarling beast of a car that isn't happy until its devoured some tarmac. Now there's a way to make your GT a bit closer to the GT350.
Ford Performance is offering a series of Power Packs that give your "standard" Mustang GT a bit more juice under the hood. From the dealer lot, your stock Mustang GT's 5.0-liter V-8 produces 435 horsepower and 400 pound-feet of torque. By comparison, the Shelby GT350 nets 526 horsepower and 429 lb-ft of torque courtesy of its 5.2-liter V-8.
All of these Power Packs make use of some method of bringing more air into the engine and recalibrating it. This gives the car the ability for no-lift shifts and improves throttle response. The first Power Pack adds a K&N high-flow air filter and adds 13 horsepower and 16 lb-ft over the stock ratings. Torque also increases by 40 lb-ft at 1,500 rpm.
Power Pack 2 swaps in the GT350 cold air intake, an 87 mm throttle body, and a special intake adapter. Engine output rises by 21 horsepower and 24 lb-ft over the stock peak output, and there's that same 40 lb-ft torque gain at 1,500 rpm.

Finally, Power Pack 3 adds the same bits as 2 but includes the full GT350 intake manifold. Here you gain 37 horsepower and 51 lb-ft of torque over the stock output. At 7,500 rpm you'll see a 60-horsepower gain compared to stock.
All three Power Packs are 50-state legal and all also require the use of 91 octane fuel or higher. Power Pack 1 goes on sale around August 1st and will cost you $539. Power Pack 2 is slated to arrive in September and will run you $949. The most powerful Power Pack is available in October and you'll need to shell out $2,395 for the pleasure of its additional grunt.
