I'm going to school for high performance engine machining in N. Minnesota, and our prof worked on a semi-pro diesel pulling tractor for a farmer out of Wisconsin. He claims farmers like tractor pulling because you can write them off as "new combine motors" in your taxes. The tractor (which ran on some hilarious amount of boost 64lbs or something?) he worked on kept cracking heads so they reverse engineered a billet head that apparently got past inspections. Then they started throwing pistons, so they put in billet pistons, which lead to disintegrating crank shaft problems... Fixed with an $8000 inertia (maybe cant remember the term) crankshaft, basically a super fat heavy crank that will keep it self in place with rotational force even if the motor explodes around it. Lot of power going on in those things...
