2007 FORD SHELBY GT500 OFFICIALLY RATED AT 500 HORSEPOWER
# Ford Shelby GT500 officially rated at 500 horsepower, 25 horsepower higher than preliminary estimates
# The Shelby GT500 will go on sale this summer with more horsepower than any previous factory-built Mustang

DEARBORN, Mich., May 2 - The most powerful factory-built Mustang ever just got even more potent. Final certification testing of the Shelby GT500’s 5.4-liter supercharged V-8 shows it will produce 500 horsepower and 480 lb.-ft. of torque – 25 more horsepower than preliminary estimates.

“With 500 hp and the Shelby name, this car is an instant legend," said Hau Thai-Tang, director, Advanced Product Creation & SVT programs. "This is the most powerful, most capable Mustang ever."

The Ford Shelby GT500's supercharged 5.4-liter, 32-valve V-8 is a result of Ford's experience in developing the modular V-8 and V-10 engine series. The engine is force-fed air via a "Roots-type" supercharger providing 9 pounds per square inch of boost. It borrows the four-valve cylinder heads, piston rings and bearings, from the Ford GT engine.

The 500 hp rating was obtained using the Society of Automotive Engineer's latest standard and was witnessed by an objective third party. The Shelby GT500's 5.4-liter supercharged V-8 will be built at Ford's Romeo Engine Plant in Romeo, Mich. Pricing will be announced closer to launch.

The right to purchase the first 2007 Ford Shelby GT500 was auctioned for $600,000, with the proceeds benefiting the Carroll Shelby Children's Foundation. The 2007 Ford Shelby GT500 goes on sale this summer.

Oh sweet jebus! 500HP/480lb.-ft.

[rage2]

It's too bad its so hefty at 4000lbs. Not that it matters too much with 500hp. It'd make a damn fine cruiser .

[benyl]

yeah, aparently the engine block, heads and blower together weight 700 lbs.

[heavyD]

A 500HP Mustang with factory warranty. Even I'd roll in that.

I wonder if its underrated like the 03/04 Cobra and Ford GT.

Damn, and I thought they weren't going to stray near the GT numbers - you could probably hit 550HP with a smaller blower pulley!

Damn, I was gonna post this yesterday but forgot

Pretty sick numbers, now if only they could do something about the weight... aluminum block maybe

EDIT it could also use a redline closer to 8000

[habsfan]

that should be one hell of a car, won't be underrated tho, it's been measured and certified with that new SAE certification. that is unless they alter the spec of it post certification
