Livernois Motorsports puts down big power with a Whipple-blown S550
By Steve Turner
Of late we’ve been seeing some huge performance numbers from modded 2015 Mustang GTs. Clearly the lessons learned and carried over from the RoadRunner engine program are working out quite nicely on the everyman’s Coyote engine. Cases in point are some new dyno results from a Livernois Motorsports-tuned 2015 Mustang equipped with Whipple Superchargers’ 2.9-liter supercharger system.
Livernois baselined the car, then installed the standard Whipple supercharger kit with the stock throttle body. Then the company stepped up to Whipple’s large, oval throttle body. We know positive-displacement superchargers hate inlet restriction, but this test makes that case quite clear.
You can watch the progression in this video…
As you can see, these results were produced on a stock car with the supercharger kit and tuning, which is quite impressive.
