Horsepower is horsepower?
If that theory is true (in real circumstances), then a 385hp 6.7L Cummins diesel shouldn't spank a 381hp Toyota Tundra when both are tested 0-60 towing a 5740# boat. But it did. Must be the adva...

Both the torque curve and the HP curve for the 2011 Cummins are higher throughout the entire powerband, right up to where they meet at 3000 RPM.The advantage the 800 has is not peak HP or torque at peak HP RPM. At peak HP, it is producing the same amount of torque as the 650 but because the 800's torque peaks at the same 1600 RPM as the 650, it will be producing more HP at every engine speed until it reaches peak HP RPM which is the same 350 HP at 2900 RPM for both engines.
Unfortunately, a lot of people will notice the 2011 pulls harder, say "but both have 350 HP," and conclude that HP is therefore irrelevant for pulling. The problem, of course, is that they'll be comparing only peak numbers rather than comparing the curves.
