Brake horsepower is the same as SAE values and is not worh a (BEEP), DIN
(Deutsche Industri Normal) is what the engine pumps out on the flywheel when it
is installed in the car (Thats why the lower value in, lets say, California)
and is the real output you have to your disposal, basically the same as net hp,
but an a/c is not included because it will not be running all the time and will
be a bigger factor than i.e. an alternator, which is a variable factor (between
0.5 and 2 hp.).
