One of my co-workers who has a new Ford F250 4wd PowerStroke had a scare this past weekend. He was out in west Texas around Sonora pulling a flat bed trailer with a tractor on it. He started pulling up a fairly steep hill. The trans downshifted as expected. The engine rpm's went up as expected. Everything was going great when all of a sudden "BOOM" . The hood appears to jump up about 3 to 4 inches and then settle back down. Engine keeps running so he pulls over, gets out and lift's the hood for an apprehensive look. Turns out the truck pulling up a steep hill was under some pretty strong turbo boost. The fresh air hose from the turbo to the throttle body blew off. The about a 4" diameter clamp securing the hose was not quite tight enough. The screw on the hose was pointed up and put a nice little ding in his hood from the underside. He was quite relieved to find that was all it was, but a little annoyed at the dent in his new truck.

is there special compression ratio requirements for a diesel like there are for a gas engine???
