Inside Line takes the 2011 Ford Mustang GT 5.0L V8 to the Dyno

While many other publications busied themselves doing burnout in the 2011 Ford Mustang GT, the geeky folks at Inside Line decided to see just how much horsepower the new 5.0L V8 is providing the rear-wheels.

Inside Line’s findings:

With 250 lb-ft on tap at 2,000 rpm, torque starts out pretty strong. It then builds linearly and remains above 350 lb-ft from 4,150 to 5,500 rpm before tapering gently to the 6,850-rpm fuel cut. Peak numbers are 365 lb-ft of torque at 4,350 rpm and 395 hp at 6,600 rpm. All of these at-the-wheels figures were obtained in 4th gear on a Dynojet 248 chassis dyno and include a 3% SAE weather correction factor.

They say that the driveline loss for a solid axle-equipped car like the Mustang is typically 11-13 percent so we should have expected to see about 358-367 rear-wheel-horsepower from the 2011 Mustang GT..

The question now is, is Ford being conservative with its 412-hp flywheel rating – we definitely think so.

Refresher: The 2011 Ford Mustang V6 is powered by the 3.7L V6 Ti-VCT making 305-hp and 280 lb-ft. The 2011 Ford Mustang GT is powered by a 5.0L 4-valve Twin Independent Variable Camshaft Timing (Ti-VCT) V8 engine producing 412-hp with a peak torque of 390 lb-ft. Transmission choices for both models include a 6-speed automatic with a 6-speed manual offered as standard.
