Wouldn't you expect a naturally aspirated engine to be at a much greater disadvantage than a turboed engine at higher elevation?

Yes, and I stated that it was impressive multiple times in this thread. However, I was just commenting on Fish's post were he said the 7.3L almost had the same time as the GM and Ram diesel pulling the same weight. I was merely stating that this was due to the 60 mph speed limit and that even the new Powerstroke would have a similar time due to the max speed of the test. All three diesels would likely be able to accelerate past 60 mph especially at the bottom of the hill. The 7.3L on the other hand was giving it all it had just to get close to 60 mph. Not saying it isn't impressive because it is.

Edit: How are you comming up with a starting elevation of 8835 ft? The elevation of Silverthorn is 9035 and Dillon is about 9100 ft.

Look at it in Google Maps in bicycle mode.

I think you're right that the elevation gain is 2300 feet. I used an online elevation tool and got the same numbers but by using the elevation of Silverthorn and the elevation of the Eisenhower tunnel I get numbers that made the run a little easier. I was trying to come up with a way of making the Ford numbers believable. When you use 2300 ft as the elevation gain and 7.9 miles as the distance covered it becomes almost impossible for an engine with the new Powerstroke's specifications to do that run in 10:20 operating at the low rpm it ran at. It is also interesting that when you plug 500 HP and 7800 lbs into a 0-60 estimator it spits out 6.75 seconds which is what the Powerstroke was measured at by TFL.0-60 estimator This calculator predicts the 0-60 time (7.5 seconds) of my 440 HP 2017 Powerstroke almost exactly. It makes it hard believing Ford's power numbers.
