WHat matters at the end of the day is getting up the hill. Drag races don't do that.
I look at this way... The truck that gets up the hill the fastest is generally the truck that can pull that load up the hill the easiest. :W
Disagree...I KNOW my truck isn't the fastest off the line, BUT IT SURE TOWS MY 16,200# efortlessly through the mountains that I tow in...Seeing as how I'm not seeing how fast I can run light to light, or drag racing a truck that weighs right at 9,000#. I I know what I know about my truck from putting about 21,500 miles on it at this point, and that's this; it wasn't built to race, it was built to work, and that is what it does in a most excellent way.
Lot more to towing up a hill/mountain, other than just how fast the truck could do it when not towing...with a heavy 5er hooked to the truck being towed up the mountain, the cooling system as well as the tranny figure more into it in a different way than setting at a stop light and seeing who can get from 0 to "whatever" in X amount of time...Childish at the least..
I don't think he meant racing to be first. I think what he meant and you will probably agree with me is that most of us when we pull a hill will push the truck to a comfortable point and stop. What it runs is what it runs speed wise. Don't you new truck pull your load up a hill a little faster with the same effort than you older Cummins trucks did?
I believe really that that is the main reason the Cummins is liked so much. It makes it's power down low where normal cruising RPM are so it makes towing feel effortless compared to having to rev to get to it's power.
The Ford 6.7 makes its peak horsepower at 2800 rpm, The Duramax at 3000 rpm and the Cummins 6.7 at 2800 rpm.
So power wise other than the Cummins makes less horsepower has nothing on the other diesels as for the rpm that it makes the power at.
Yes , all the trucks now days are close at where they make their power. I guess I was referring to past years motors. The older Powerstrokes peak torque was at around 2000 rpm while the Cummins was at 15-1600.
I am sure you will find the lowest rpm that any Cummins has produced it peak power is 2900 rpm which is 100 rpm greater than the 6.7.
The 1994 Ford Powerstroke 7.3 made its peak power at 3000 rpm.
Peak horsepower rpm is where an engine makes the most power not the peak torque rpm.
