Yes factories always state crank/flywheel horsepower. In the US it is generally reffered to as horsepower but in other parts of the world it is reffered to as brake horsepower bhp. I do not know of a signal manufacture that tells rwhp numbers.

By the way the 225rwhp number seems pretty low. I would expect it to be in the 270rwhp area... I guess their mustang dyno is reading really low.
