This is more of a theoretical/curiosity question. I’m guessing the most practicable answer is to use a vacuum gauge.
Is there a way to measure how hard the engine is working? I’m guessing that to make an actual “power reserve” gauge, you’d have to put the vehicle on a dyno and measure all throttle positions for all rpms, then use that in a program of sorts. How close would a vacuum gauge or throttle position gauge be? Maybe air or fuel flow? Guessing exhaust pressure/flow would mirror the intake? It’d all be rpm dependent so I guess it’d just be a gut interpretation unless you hook sensors up to some kind of comp.
