All manufactures rate horsepower at the crankshaft when it advertised. It is full accessories and emissions.
Not exactly. Especially for those who use J1995.
J1349 is used by the manufacturer who makes the completed vehicle while J1995 is used by the manufacturer who does not. For example, Cummins uses J1995 because they only sell engines and do not make a completed vehicle.
You are right, I should have been more specific. I was thinking GM, Ford and Mopar. When they advertise cars it is at the crank. I would assume it is the same for the Diesels, but I never really thought about it.
