Modelling engine wear and WEP limitations

The reality is that most combat aircraft were destroyed before their hundred hour checks, and 25-40% of RAFFC pilots died before they achieved 100 hours of combat flying. The Merlin engine could be flown continuously at 12lb boost with a low probability of failure and this engine was cycled 100 times from 4.5 to 12lb/3000rpm and the bearings held up just fine:

without the need for repeated engine checks, since by definition the engine was being cycled multiple times per sortie.

Sorry, but the fact that you claim continuous running on what's called emergency power and then try to support it with the argument that most planes would be destroyed pretty fast anyway, makes it all sound like an effort to disguise the fact that if the aircraft survived long enough they would get a higher proportion of engine failures.

It would be more accurate to phrase this a bit differently: engine failures were rare not because WEP was free of charge, but because the aircraft rarely survived long enough for the engine abuse to take effect.

Like i said before, they wouldn't call it emergency power if it was fine to use it all day long and fuel burn was the only real drawback. They would just call it full power and insert a footnote "warning, it burns fuel really fast".

Emergency has a pretty strong connotation to it, it means "don't use unless you're about to die" in simple terms.

And finally, this is not a thread about what the Merlin could or couldn't do. This is a thread about modeling engine limitations on ANY kind of engine in the sim if it also had them in reality. If the Merlin did or didn't have such restrictions is a completely different matter and totally out of the scope of this thread. What are doing here is this:
"Supposing engine X has limitation Y, what's the best way to have this reflected in the sim?"

Why do you feel the need to constantly hijack this thread in the direction of the Merlin specifically is completely beyond me, especially when you can just as easily start your own thread and argue your point there without dragging this one completely off-topic.

We are not discussing the capabilities of a specific engine here, we are discussing a proposed idea for a game feature. If you want the Merlin to be exempt from it, feel free to start a separate thread about it or use one of the many already provided. We don't need every single thread around here to revolve around the Merlin and the use of 100 octane fuel, there's several of them already

Excuse me the bolded text, i mean no hostility and it's purely for emphasis. It's just getting mighty tiresome trying to discuss an interesting idea with some like-minded fellows in the pub and having someone from across the bar constantly jump in the middle of your group shouting "AHA" as he dumps a load of old musty dossiers and charts on the table before he starts on something that has almost nothing to do with the discussion at hand. Don't drive us out of the pub man, especially when there are people having the kind of discussion you prefer just two tables over
