These engines are amazing, some of the truck pullers run twin turbos, propane and nitrous, oh and some up to 75 plus PSI of boost... One racer was quoted as saying that you could feed these engines hand grenades and they would live... they typically don't spit the crank or rods out until around 100 PSI of boost. The rod bearing journals of a Cummins 5.9 are bigger than Chevy 350 mains!!!
