2005 Ford Mustang Gt Dyno Test 2
|
In this comparison, the GT500 throttle body and adapter plate when installed on the factory intake manifold equipped with CMCV delete plates increased peak power from 410.96 to 414.65, for a gain of 3.7 horsepower-though we saw as much as 6 horsepower at just under 6,600 rpm. Out of curiosity, and because we had the parts, we reinstalled the stock CMCV plates with the GT500 throttle body throttle body, and the engine produced 409.08 and 411.28 hp on back to back pulls, thus showing that they are a restriction once the throttle body has been opened up.
