Hehe how many topics can you find where Toad, Lazs, and Funked are actually in agreement?

There was NO "practical" limitation on max power use, only maintenance-oriented "operating guidelines." The only limit on WEP was the duration of the injection tank. Dogfights in the sim last about the same length of time as dogfights in real life. Why would you want to impose a combat restriction that didn't really exist?
A FAR more worthwhile system would be to model "Combat" and "Cruise" settings for your whole engine/prop/mixture combo. Select "Cruise" and your plane is configured for "economical" climb and cruise to target area. Then, with ONE keypress, you go to "Combat," your prop goes to fine pitch, RPM to max, mixture full rich, drop tanks are punched off, and you're ready to fight (with WEP as a separate function, limited only by its tank capacity, or by a time limit for the planes that only used over-rev or over-boost). Make the transition from "Cruise" to "Combat" take varying amounts of time (0-8 seconds or so) depending on the complexity of the airplane.
Slightly "abstract," but models the "reality" pretty well. Engine management is a VERY basic skill. It might take a few seconds of TIME to set your plane up right, but it wasn't something that an "ace" could do right but that a rookie would screw up.
I don't see folks clamoring for a "realistic" engine-start sequence complete with checklist, warm up time and engine run-up before takeoff, so I suspect "realism" isn't at the heart of the desire to see engine overheating and full engine controls modeled
