I was just working on a project tonight – and ran across this great chart.    It’s an old-fashioned draw-a-line 2D calculator.

So it’s possible to have 100HP at with 10000lbs of Foot-Pounds torque at 60 RPM.  Then you break your engine.  Enjoy!

Thanks to the electric toolbox http://www.elec-toolbox.com/ for the graphic.
