If it seems like we make a big deal about tuning firm Roush Performance, it’s because such attention is warranted; few companies so thoroughly vet their products before making them available for purchase, and we believe that commitment to excellence shows in the quality of the packages offered.
The video above takes us behind the scenes of some of the validation testing conducted by Roush Performance, with narration by engineer Blaine Dover. This particular validation testing regimen is being conducted on a 2015+ Ford Mustang GT with the firm’s “Power Pack,” including a cold air intake, performance cat-back exhaust, and a Roush Performance engine calibration.
To figure out how much rear-wheel horsepower and torque is added by each component in a “real-world setting,” a factory stock Ford Mustang GT is first tested to acquire baseline figures. Then, each component is installed one-at-a-time, with dynamometer tests every step of the way, followed by tests of each possible combination of parts. This is important, as “every combination can have a different outcome on the horsepower and torque from the engine.”
Using the same car for each test, it should be noted, is also good practice, as values might vary slightly between one car and another depending on the level of break-in.
