ClickThis data suggests that if Ford wants a clear victory over the Duramax they might need to bump their power a little more yet. I am totally satisfied with the power of my '11 ..... I wish the battle was more over fuel economy figures.

I seen that test on YouTube, The testers don't know what they where talking about. They looked at one Rv and read out the Max weight limit(12050), not the Dry weight(9800). And then claimed all the 5th wheels where around 12000 pounds, despite they where all different lengths and manufacturers. I looked up the dry weight on the other two 5THW and the one pulled by the Ram was 10700, The Chevy's was 9800, and The fords was 10600 pounds. I thinking of getting a tune for my F-250.

Same sled, same weight transfer for all the different makes. I honestly expected the Cummins powered trucks to win.

Simple reason more horsepower in stock form.Saw similar results at a tractor pull a couple seeks ago. What was interesting it was sponsored by Ford with no shows. Possibly could not enter with them sponsoring the event. But in the dirt drag racing there were some older Fords. Never saw a 6.7 though. The Duramax was king in the dirt drag racing (400 ft track)Modified a different story. The Cummins has a much stronger block thus can handle bigger tunes.

THey are higher than the current Dmax 397HP/765TQ. Which begs the question how they are getting those numbers?

Probably the same way they got bigger numbers back in 2011.. The Dmax was dyno tested under strict SAE standards. The other two... NOT.
Think about the difference between peak and continuous ratings... BTW, The Dmax power numbers is the same as it was back in 2011.

The highest powered Cummins is still 12 hp short of the D-max. I don't think Ram has ever tried to claim top prize on hp or speed.

I've towed that section of I64 many times, very long grade of several miles at 6% and the last 4-5 at 7%....Towed my 5er up it about a month ago....it'll tax a truck...5er weighed in at 16,200#, I hit the "bottom of the mountain" at 65 mph and topped it at 65 mph, no problem..It's normal when it's hot and humid in that area to see semi's as well as people driving Motor homes, towing TT's and 5er's to be pulled over due to overheating.. I can think of a couple other mountains they could have towed up that would have tested the vehicles also, on I26 and I77, but, the New River Gorge is a long steep run...

appears Chevy hit the highest speeds:)......heck, I know what my truck can do with 16,200# up the mountain and it's more than enough, it's obvious it's the same for the Ford and the Chevy....speed limit is 70 mph and I don't tow that fast, but am half tempted to see if I can top that mountain now at 70, you know just see if it could do it..:)

You are correct...don't know the actual new GM/Chevy HP & TQ numbers, but understand, I think that the Ford is 440/860...where as the Ram with the Aisin is 385/850...

When it comes to towing a trailer up a particular hill the most powerful truck doesn't necessarily win and just because one truck out performs another on hill A doesn't mean it will be the top performer on hill B. The Ford makes 440 HP at 2900 rpm but if the hill is such that the computer is keeping the transmission in 3rd gear at 1900 rpm it may only have around 290 hp at its disposal. The Duramax might be running that same stretch of highway in 2nd gear at a much higher rpm. I own both a GM and Ford and find the Duramax Allison is designed and programmed to operate at a much higher rpm than the Ford.
