HP = torque x RPM. To get the units to work out you multiply by 5252. It’s really straight forward.

I have a 6.0 gas engine in my 3/4 to Chevy. When flooring it to pass, I never bother to push it beyond 4,000 rpm. At that rpm, it’s already making 300 HP, and is way more than needed to get the job done. Any more rpm than that, the torque starts to fall, and the HP curve increases at a slower rate. Less bang for the buck and probably more engine wear.

That is one screwy graph. Because the scale of units is different, it pushes the "crossover" to a bizarre point; appearing to happen at 2626rpm. (when the relative scale is at a factor of 2x, the crossover appears at 1/2 of the "normal" 5252 ....)
While technically not "wrong", it's just not "right" when you look at it.

one horsepower is 33000 foot pounds of torque per minute, or 550 ft lbs per second... but that is one definition of power,, there are others.
