P39 mixture

[Higaluto]

So i have been getting into the p39 trying out engine limits etc, and the aircrafts specs says you have 2min of full power with 100% mixture setting.

that is actualy quite nice as the g6 only gives 1 min.

 

but if you fly at full power with 66%mix auto rich, does this effect your performance, and does 100% mix give better engine cooling, i know from other ww2 aircraft you could use emergency rich to spray the sylinders with fuel and thus cool them. Is this so, and is this modeled in-game?

In game practice (so far) you can run 66% mixture whole time in the P-39. The 66% improves performance somewhat at higher boosts (100% is slower) but results in extra heat.

Don't overlook radiators, thought - 60% for the water and 45% for the oil is the "flush" setting needed for the best performance.

Try to conserve your boost time, too - WEP is powerful but once used up you will have to do with the nominal which is... not great.

Yes it is, you can technically run War Emergency Power in P-39 with Mixture set as Auto Rich but with Full Rich you will decrease the temperature so it's recomended to do so.
