So that sterling engine would be outputting 115.5 lbft of torque @ 1500 RPM?

115.5 LBFT x 1500 RPM = 173250

173250/5252 = 32.9 HP

Or for your estimate, about 70 lb ft.

70 LBFT x 1500 RPM = 105000

105000/5252 = 19.9 HP.

Most car alternators, and welding apparatus generators, are built to create max output at a given RPM range, I believe most car alternators peak at about 3000-4000 RPM, which is why I used that for a figure.
