2005 Ford Mustang Gt First Dyno

The first test we performed utilized the stock intake manifold and throttle body, and the factory charge motion control valves (CMCV). We then installed the CMCV-delete plates for comparison. Despite the relatively high-horsepower nature of the engine, peak horsepower only increased from 409.08 to 410.96, and for the most part, power was left unchanged throughout the pull. In a couple of areas, gains of 2 to 3 hp were shown. For the average street car, they would not seem to be a cost-efficient horsepower upgrade, but on a max-effort naturally aspirated setup, every single horsepower counts. View Related Article
