Spit 2a overheating...

Glad they're aware of it, and glad it's suggested as a high priority fix. Leaning the mix to cool the engine is absurd.

Agreed, as is selecting Auto lean to get smooth operation with Boost cutout .... also snagged with the devs.

Great to hear that the devs are aware, thanks IvanK.

Question how u understand the 5 min boost limit?

For me its like for the 109, u can use it for "5 mins" depending on temperature, after cooling and reaching normal temps and one can use it again.

Sure it stresses the engine, and all the Pilot has to do,is to tell the groundcrew that he has used it, so that they can decide how to inspect the engine.


i am referring to these both links: have a look in it ;D

The 5 min limit (like the other limits) is based on engine longevity not an absolute limit. The intent in the RAF context is 5 mins per sortie. There is nothing to stop you using the way you suggest though all that is likely to do is reduce the longevity of the engine.

I always warm the water temp to 60 degrees or preferably 80 before moving at all. I don't take much notice of the oil temp in any of the Spits while I'm on the ground.

Once the water is up to above 60, take off at max revs/max boost, without engaging 'emergency' boost. Gear up, and allow airspeed to exceed 185mph before throttling back to +4 boost and changing prop pitch to give 2800rpm. Throttle adjust to give +5 boost, or + 6.25 if you're in a rush. Then watch your temps, and reduce revs with prop pitch if oil exceeds 95 degrees, reduce boost if coolant exceeds 110 degrees. Your engine won't blow because of water temp until 120 degrees. Set your rad at halfway open/closed.

For a nice relaxing climb, set revs at 2500rpm and throttle to +5 boost. Unless there are bogies above your airfield, why stress your engine? Climb rate at 165mph, 2500rpm and +5 boost is about 2000ft per min.

This is from memory, so some specific mph/RoC figs may be slightly off. But don't fly your plane at max performance everywhere at all times. It wouldn't happen in real life, so it shouldn't happen in the game.

Very helpful, thanks.
