A major shop (livernois maybe?) did their first pulls in 4th and got like 390+. But they re-ran again in 5th and still put down around 375, which is 430 wheel. Its no secret ford underrates their motors after overrating the 99 cobra.
Other shops have had less, such 360rwhp SAE on a dynojet. If the motor is SAE certified, it makes 415hp, give or take 1%. I still don't know if it is though. Why is it 430 at the wheel? What % is being used to come up with that number? Happy dyno's but we don't race dyno's. Same with LS3 motors making 390rwhp while rated at 436....a happy dyno!!!
