What is the minimum temperature difference needed to operate a 2 cylinder Stirling engine? Is there a temperature point where efficiency is greater?

This information is for a school project and I am having a hard time finding this information and a friend told me that if anyone would know it would be the people here on Practical Machinist.

If i'm not mistaken, you'll get a pressure difference of .05 psi for a 1 Celsius increase in temperature at 300Kelvin, or 27Celcius.

If your engine has less friction than it should run.
