Are the HP wars over?

Torque is what counts when hauling a load.

LOL, I wish you would tell that to my 440ft/lbs of torque 6.5 when I'm doing 25 MPH up a hill and a 5.3 gas rig with 383ft/lbs comes blowing past me like I'm standing still pulling the same or bigger trailer. :R

How I like to put it: ultimately, HP gets a load up a hill (as per Newton). Torque is simply a way of making hp, via rpm.

But if an engine ONLY has torque (2000 lb-ft @ 150rpm), it's getting nowhere fast.

Another law of physics: you can always CREATE torque with gearing, but you cannot create more power.

area under the torque curve in the rpm range used with the gearing you have is what counts. highest peak HP does not always equal best performance.

and actually 1 million lb-ft @50 rpm and direct drive to the prop gets the big ships with the Sultzer diesel moving pretty well.
