Figuring that Metra has the MPI Mp36 Engines running as a coverage for the GP39s and any older engines. I was wondering how are those engine hanging around there???
I love the smell of Diesel Fuel in the Morning!! ;)

And why?is this the BHP from the prime mover.. or the wheel HP? if it's wheel hp, then obviously you have to factor in the HEP load.... but if not... then i don't know.
