Interesting.

Looking at the three other aero-diesel manufacturers, it looks like their
engines are competitive on both weight and fuel consumption.

Zoche aero-diesels. (air-cooled)

Centurion Engines (liquid cooled)

On a turbine engine, turbine inlet temp is the most important parameter
followed by power turbine rpm.
