We put this stock Pony through its paces on the dyno. All testing was done in Fifth gear to ensure accurate readings, as the '11 Mustang's six-speed manual transmission features a 1:1 ratio in Fifth gear. Previously, all stick-shift Mustangs were tested in Fourth gear, as that yielded a 1:1 ratio. In stock form, Frank Lanzas' tester put down 374 hp and 360 lb-ft of torque to the rear tires. To put this in perspective, the famed '03-'04 Terminator Cobras put down around 370 rwhp in stock form-these new 5.0s are bad!
