Is it torque or something else? And if so, can you derive anything from that? (pun fully intended.)

This is a math joke. I don’t get those.

Semi related: how about the integral of the power curve to show the area under the curve? Then you could more accurately compare a big NA V8 with a high-revving I4 using a much better metric than peak bhp.
Not my original idea, I think I read it on Jalop about 10 years ago.

Hammerheadfistpunch has talked extensively about this very subject.

Force Per unit time. 1 HP is 550 ft-lbs/s.

A derivative is just the tangential line to a point. Although I probably worded that so that it didn’t make sense.

But it’s the tangential line at a point, AT EVERY POINT, which makes another line....or a lot of lines....

cept the math bit. I could never into math, which is why I was a communications major! But yeah, average power would be a great way to compare. Sadly no one publishes power charts...except GM for some reason.

That’s an awesome idea! I wonder if you could also use that with gear ratios to figure which car will have the most torque/horsepower at the wheels?

It is a fantastic way to see how useful the powerband is for normal driving conditions. It would show that an RX8 sucks and a Ford with a 24v V6 is much easier to drive.

I think we need to spam David Tracey’s email until he does an article comparing some motors this way.

This really gets into partial differential equations.
Depends. HP = Torque*RPM/5252.
If you take the derivative of HP with respect to RPM dHP=(RPM*Torque/5252)dRPM would be HP’=Torque/5252
However if you take the derivative of HP with respect to and arbitrary variable, say x. Then dHP=RPM*Torque/5252dx would be 0.
I’m not sure how useful those would be. You could do dHP=RPM*Torque/5252dTorque would be HP’=RPM/5252.
You could do dHP=RPM*Torque/5252dRPMdTorque. But I think that gets to a constant of 1/5252.
It’s been awhile since partial differential equations, so I’ll need someone to check my work.

The time rate of change of the ratio of the horsepower to the rpm.
How quickly your horsepower:rpm changes, not very useful.
