I would like to also know the ambient air temp as well as coolant and tranny temp of the these trucks when they reach the top. That to me tells me more about the capacity of the pickup than does speed/time up the hill alone.

Exactly. The video lacked those kinds of details which I was wanting to know.

There is a reason they did this where they did this and when they did this. I would bet money it was no accident there was snow around when they did this test.

There was a reason they did not do this test on a 105 degree day on the Cajon pass.

There is a reason boats with the same engine as trucks are rated at a way higher HP and way higher duty cycle.

It's easy to make any HP you want. It's extremely difficult to handle the thermal load for that high HP. Ever see the fan or radiator size on a 6.7 Ford, 6.7 Dodge or 6.6 Chevy? :E
