One info about the C182 briefing we did a while ago.
Marius (i think it was him) asked me if you can exceed engine limits. In the simulator, of course you can.
However: I now found some real aviation forum posts[1] that mandate to reduce power as soon as practical. And that is not obvious from the checklist, but its basicly the question about when to go from the "takeoff"-phase to the "enroute climb" phase.
They said that one should reduce power as soon as all obstacles are cleared.
A reduction to 25MP manifold got me to about 15Gph fuel flow when leaned to max power and kept the CHT hot but not exceeding the red line anymore - i think this depends alot on the current weather and weight of the plane.
That said, one thing may(!) be that the CHT heats a little too fast. I still have no real data to adjust this better. Btw, what does a cylinder head weight (currently its fixed at 4Kg per head, but that was arbitarily choosen. Probably too low, the entire engine weights 400lbs/136Kg!)?
EDIT: found a source listing it at 21.75LBS (~9.8KG). I tested that and it looks sensible:
https://github.com/HHS81/c182s/issues/444; climbing at max power to pattern altitude is no more a problem.
