The engine has an integral gearbox that produces 650 RPM at WOT. Not having any experience to go by, I was concerned about being able to turn the pump at it's rated speed of 1000 RPM, so I went with an 18 on the engine and a 12 on the pump, which according to my math should turn the pump at 975 with the engine at WOT.
Obviously, that's MUCH too fast, but even with the engine at idle (I haven't put my tach on it to see what that is) it's too much flow.
I will be re-gearing, but I have another solution in mind that I'm going to try this morning. If it works, I'll post the details.
