The engine analogy is not a great one. Those inputs and outputs are very crude information. The actual design of an engine is quite complicated and subject to very close tolerances. Your analogy is like going to an airport and looking at departure and arrival times as well as the flight path and then “reverse engineering” an aircraft from that. The chances are very low that you produce anything remotely resembling the aircraft you’re trying to reverse engineer. Same goes for the engine.
