What does the 120% setting mean in the Corsair?
What does it do other than make your engine smoke, and when do you use it?

OK, that makes sense, more O2 down low so you can burn more gas, I'll try that.

Surprisingly the R2800 (and many other) engines do not develop maximum power with an overly rich mixture, as it is significantly higher than the stochimectric ratio for best power. Full rich bypassed the automatic mixture feartures ofthe injection carburator and was usefull for starting and in case of a malfunction. Additional fuel was somewhat usefull in the pre-water/meth installations in providing extra internal cooling, allowing use of a higher manifold pressure without detonation setting in. Water methanol injection was a more elegant solution to this problem, preventing detonation, better cooling and use of a LEANER mixture to produce more power.

The main reason "water wagons" developed more power was the ability to use a leaner, more proper mixture for best power, without overheat problems. This eventually allowed higher limiting manifold pressures as well, and even morepower.

What the sim implimentation of this is, I have no idea, though the patches seem to be more realistic.

Use full rich (120%) when going for max power on the deck, such as for takeoffs and landings (you want that power available). Then auto rich (100%) on the climbout.
