2013 Shelby GT500 shows more power after dyno test [Video]
At the press launch for the 2013 Ford Shelby GT500 last week in Braselton Georgia, Steve Turner, editor-in-chief of 5.0 Mustang & Super Fords magazine, wanted to run his own dyno test to see just how much horsepower the new muscle car has, and was able to sneak one of the cars away for a quick test. Apparently even after driving one of the super fast Shelby GT500‘s, he needed to see for himself if Ford’s claims were true.
As we reported here on Torque News, just a month ago, Ford announced that the 2013 Ford Shelby GT500 had been officially SAE certified with 662 horsepower and 631 lb. ft. of torque. This was a dramatic increase over the incredible 650 horsepower that Ford had announced back in November of last year. This made the new aluminum block 5.8-liter the most powerful production V-8 in North America. However, as reported by Mustangs Daily, those numbers may not even be an accurate representation of what kind of horsepower the 2013 Ford Shelby GT500 is pumping out.
The 2013 Ford Shelby GT500 goes on the dyno
In between laps at the Road Atlanta track and making quarter mile passes at Atlanta Dragway, Turner took one of the new Shelby GT500’s and put the car on the dyno for a quick test. After getting the car up over 6000 rpm’s Turner found that the 2013 Shelby GT500 was putting out 609 horsepower at the rear wheels.
