I give you a link from the masters of diesel engines and you give me "how stuff works"? Torque is a component of horsepower. More torque gives you more hp at lower rpm. More hp gives you more torque through gear reduction. Nothing to get a headache about. If you want to know how much torque you need to run 60mph up a grade, you first have to figure how much horsepower is needed no matter what fuel you're burning. Then you have to decide what rpm you want to run. Then you can calculate how much torque is needed to produce the necessary hp at the desired rpm. But it starts with horsepower as the Cat site spells out clearly. You can't get around that. I ran my 250hp Cummins at it's peak hp 2900rpm many miles. My '98 12v Cummins with 5spd/4.10 ran at it's peak hp 2500rpm at 70 any time I was running 70mph. The 5.7L Hemi, during R&D, was run hundreds of hours at peak hp 5400rpm full load. Tear down showed only normal wear. Won't hurt a thing.
Why are you starting to tell me what I've been telling you and passing it off as your own? Torque is a component of HP. Torque without rpm is a static measurement. It implies no movement at all. Torque with rpm is known as horsepower in our application. Already been said.
