Torque vs Horsepower?

[jim lee]

It seems that there will never be an answer will there? On and on the old fight continues. Well, its time to take sides and put your money where your mouth is.

What camp are you in? Horsepower? Or would it be Torque?
Now, when entering those internet flame wars, you can display your camp's official Torque Vs Horsepower battle gear.

Lost of opinions and controversy. I got the 'torque dont move anything tshirt'

If you are below 5,252 RPM you beter build for torque. Above 5,252 build for HP.

I agree with ya Info torque moves the mass and gets it going then horsepower takes over.I played with that as in impellers mine won't run till it gets on the pipe. 7000 rpm is were it likes to run.Had every impeller in it and turned some down and that is what it takes for every different setup boat/HP.

Info is right 5,252 RPM is the magic number.

We went through this last summer about the "5252 rpm" deal. That number is actually meaningless in terms of performance. Purely an anomoly of the math involved. It is only the torque=hp point in our measuring system. Take the exact same engine, measure torque and power in metric units and that crossing point doesn't exist.
For a long time, I too was a believer....

OldSquirt is correct about it being mathmatical.
A better term would be just to say "power" at a certain RPM.
There are still large differences in engine components designed to make power at low RPM's and those designed to make power at higher RPM's
Choose them to compliment the RPM's you intend to turn. If you decide to run it on a dyno to see what it does. You will need to speak dyno language. Torque and HP.
It just happens that Horsepower is the unit of mechanical measurement to rate engine power. It is measured on a dyno. Dyno's measure torque. You have to mathmatically convert torque to HP. wink
