The Manufacturer measures HP at the crank, before it even enters the transmission. As billybongo63 said, the numbers he's giving is what actually makes it to the wheels after it goes threw the transmission, transfer-case, differentials, wheel hubs, etc., and on a dyno that doesn't try to fudge the numbers.
