Basically HP is acceleration, torque is twisting power, Your highest HP will be at the point of a curve where the product of RPM and torque is the greatest.
A dyno can not measure HP. It only measures torque and RPM.
Torque times rpm equals power. To compare that to a real horses power you have to divide by the constant 5252.
To rate yourself in elephant power you would have to make an estimate of how much power a elephant makes, make the calculations the same as Watt did, and replace the 5252 constant with your new elephant constant.
The 5252 number is not exact. It's just a number that is used in all HP calculations. It was a steam engine salesman's pitch to sell steam engines.
And that is why the Cummins with almost 100 more ft of torque got waxed towing up a hill and at the drag strip. The Chevy put out more HP so it was faster up the hill.
Nothing amiss at all. The math works. The Chevy had the most HP and beat the Ram up the hill.
