Never run across a stirling engine site that had such, "to the point" information and suggestions on their design. I also was able to "finally" find a copy of NASA's Stirling Engine Design Manual #1. Again my thanks for the time, the effort, and the sharing. A “Very Well Done” website!

But in any case, to download it you go to the main page http://newenergydirection.com. You then click on the menu button “Stirling Engine”, and then follow the instructions.

The speed shown in the graphs is for hydrogen which has low density and low viscosity, which results in higher engine speeds (since pumping losses are lower). The MOD II Stirling engine, developed in the 1980s, used hydrogen as the working gas, and it reached comparable speeds. At peak power it ran at about 4500 rpm which is 75 Hz. Also, note that predicting engine speed is among the biggest uncertainties, which is why in the design manual that comes with the program I give a speed tolerance of +25/-30% from the nominal value predicted by the program (as shown in the graph), which means that you can easily expect an actual running speed quite a bit lower than that.
