Hi Two-Bit, I have a little different understanding of the physics involved. Power equals force times speed. Force, when speaking of rotating loads is generally expressed as torque. Your 3 to 1 ratio will mean you have 3 times the speed and 1/3 the torque, in the perfect world. We live in a world, less than perfect, with things like friction and flow restrictions, which limit the efficiency of our machines to somewhat less than 100%. In your case, you may have 20 hp in at 1200 rpm, and get 18 hp out at 3600 rpm. Only trying to express a principal, not trying to calculate you numbers for you. If I am way off base someone will correct me.
