Ram HD 1000 lb-ft MPG loop
Towing 29k. Nice to see they have a gauge that tells you how "full" the DPF is now. That's handy.... VIDEO Almost 9mpg pulling 29k, which means about 37,000 GCW. Pretty incredible. Interesti...

Yes, at least from what I have seen in the dyno cells when I worked at Cummins. The crank and the internals can handle well over what the pick up truck puts out(I am talking hundreds, not tens) without any significant or even notable reduction in B10 and B50 life percentages. Have you seen otherwise in any of the engines you dyno tested when working for an engine manufacturer?
All anecdotal. In markets where there are no emissions, why don't Cummins or anyone offer a 500 kW stationary generator (say in Africa) powered by an ISB?
The first draw back is the turbo especially on the turbine side. It is a major bottleneck and causes temps to rise quickly along with high drive pressures which puts a strain on internals(and head gaskets). However, it was made to control emissions at all rpms like all stock VG turbos. It, like the rest of the hardware and tuning is made to meet emissions and therefore very conservative in regards to what it can actually handle.
Not sure what it has to do with durability.
Nope, it would not be reasonable at all. At least not with my 20+ years of experience in the medium/heavy duty industry working for various engine/truck manufacturers and dealership groups. How many years have you been the industry to come up with that theory?
I didn't ask for your credentials, and btw, are you a registered engineer or just the tech running the test bench? Why is it not reasonable to assume engines operating at lower power, which experiences lower mechanical and thermal stresses, to incur less warranty repairs?
