There was over 35 minutes worth of MW50 "go juice" in the 152 and the limiting factor was engine safety.
You could hypothetically run any engine in the game on WEP for hours on end dry or wet, and tests and isolated examples show this to be true... We can't run a game on that kind of anarchy. We use the official limitations on power settings to dictate if it was a 10 minute WEP duration or a 5 minute.
But you know this already.
Haha.. No I didn't actually. The most I did probably was read this info at a glance years ago. Thanks. I still think what I described to Karnak is true. We have combat trim - gamey. Standard tracers, arcade unhistorical restriction (not dig at HTC but calling it for what it is). 25% fuel load increments, idem. DTs + 25%, almost inarguably gamey. Auto retract flaps, basically gamey. Did all planes allow fuel tank selection? Probably, but any that didn't could be gamed at least as hard as "removing guns". Etc etc.
Hitech said it (I'll be paraphrasing) and I agree even accounting for the likely differences we ultimately have in vision or passion for warbirds/dogfighting etc: AH is not about rote realism of simulating air war. It's purist air combat with these machines. We have combat trim etc so that the planes/fights are distilled from "accounting" distractions. So that the substance of the planes and the fights are all that's left.
For me WWII was circumstantial. Germany and the rest of the world gamed WWII. Gun deletions were common enough to satisfy Pyro's (IIRC) "most common" IE "what you'd most likely see if you came across some of those aircraft in the field", and also might have (gotta check literature) come that way from factory. And AH's trigger attributions are arbitrary, optimized for gameplay.. And optimal gameplay would be least heterogeneous gun groups.
Not being able to fire 103s alone is for these reasons the same sort of arbitrary, unnecessary cramping of people's freedom to flog our planes to the max, as not being able to omit some guns that were omitted IRL.
