Exactly what facts are you wanting me to provide for you? That a gas motor will turn 9-10,000 rpms without floating the valves or a diesel motor that will run 15,000 hrs?
Turn on a car race on Sunday and watch it. 9-10,000 ain't squat. As far as 15,000 hours? Look at any big truck with 500,000 miles on it. I work on equipment that has well over 15,000 hours on it.
You made reference to this particular engine. Maybe you know something about it no one else does. I was interested in your source of information on it. That is exactly what I'm wanting you to provide. The 5.7L Hemi starts to float valves at 6300~rpm. The 5.9L Cummins starts to have problems at around 4200rpm. This particular engine weighs quite a bit more than the little Cummins pickup truck engine. I'm doubting that it can easily turn 10k rpm but prove me wrong and I'll concede. And where did you get the hours figure from on this particular engine. Just curious.
