Hello,
When you create a simple piston engine for MSFS, you first create an engines.cfg file that you set up with the basic characteristics of the engine.
Then the three more essential tables to be filled in are IMHO : engine_friction_table, engine_mechanical_efficiency_table and manifold_efficiency_table.
The most simple parameter to enter is max_rated_hp and to test it, I begin to use in the DEV Mod, the Debug Aircraft Engine window which is like this:
What I do not understand and the SDK still does not give much information on this point is that we find on this window 3 locations, surrounded by an oval or two rectangles on the capture above which indicates a power value.:
What I seem to understand is that 517 hp is the maximum internal power to the engine and that 301 hp is really the final power developed at the level of the propeller ...
If you can give me more explanations, I would be interested and attentive to yours comments.
Thanks.
PS: Then as for the maximum speed achieved by the aircraft it will depend on the parameters associated with the propeller, the geometry/ aerodynamics of the plane without forgetting the factor of Oswald.

- Power : 517/301 hp
- Total power of engines in/out : 216/517 hp
- Total power of engines out/max : 216/301 hp
