Most builders dyno their engines under "optimal" conditions which could virtually never be duplicated once the engine is in the Cobra. OEMs rate their engine in the cars, as installed, with a much more stringent SAE rating. You usually can peel off about 100 fwhp once the engine's in the car. It's all about sales hype and bragging rights.
