I understand precisely what you are saying.
One question: Does Ford do SAE testing procedures with a SAE witness or not?
If not, then you can dis the SAE standards all you want. The Fact would be that Ford tests without any "benchmark" standards. IOW, They can make up their own test standards.
Using a witness does not matter in what I am talking about since none(zero,zip, zilch, nada) of the SAE tests is sustained power. It is only short burst power. So having a witness has nothing to do with it.
Also, the tests standards(witness or not) have the same correction factors. Ford or any manufacturer could use the best correction factors today without a witness and then use the very same best correction factors next year with a witness and it would still be legit. A witness does not mean squat in this because it is legal to do witness or not, and a witness would still sign off on using the best correction factors because it is within the test parameters. I don't think you understand how the process works because you would not be saying what you are saying if you did.
So why then did the Dmax with less HP smoke the higher rated Ford for so many years?
Fact is with out a SAE witness to the testing, they can do anything they want. And get pretty much any rating they want...
I remember a MASH episode where Col. Potter was having trouble passing his drivers test, and wanted a "make up test".
his instructor, Rizzo said"Great idea, you can make up your own test, I bet you get a 100%."
It is definitely not uncommon for a lower powered vehicle to win a race. Bench racing only gets you so far. You can plug in as many formulas, weights, gear ratios etc you want but it doesn't mean anything until that tire is pushing asphalt. There is a reason we still go through the exercise of actually lining up the cars as the starting line.
Horsepower at the crank is fairly meaningless. That's not necessarily true, but what matters is the horsepower to the ground. GM over the years has done a great job getting the horsepower to the ground. Toyota in their cars and crossovers do a great job as well. They are efficient. Drivetrain loss, or lack thereof, is as important as HP at the crank.
That being said, this test in these conditions, the Ford beat both the RAM and Chevy. Hopefully everyone ups their game.
