why 95 to 90? try this: take a p38L late and go full throttle and fly as fast as you can on the deck....the plane hits a brickwall at about 470kph IAS and refuses to go any faster. Now keeping full throttle, adjust your prop pitch to 95-90% and watch your speed jump to about 570kph IAS.

not on my PC..............
i easily hit 570km/h TAS at SL with 100% pitch , not sign of any "wall" at 470.
than when reducing the pitch to ~90%, i get slower.


i'm am using that summary when flying IL2 concerning the pitch:

for all piston engined planes except:
Ki-27
J8A
TB-3s
Fw190 in auto mode
Ta152H in auto mode
Spitfire IX and VIII in auto mode
Bf109, Bf110,Do335,Ta152C in manual and auto mode:
the prop pitch in game is controlling the engine revolutions - so 100% pitch here means you allow the egnine to run at max rpm if enough throttle/power is available.
in combat you shoud fly always with 100%.
to lower your pitch is actually only necesarry if you want realy fly slow (that your comrades or the AI can close formation or you want safe fuel) , than you have to reduce the pitch like the throttle. same % rate or pitch 10% more than the throttle % is a good solution.

also using full throttle and useing only 90-95% pitch can reduce the overheat chance - usefull in some planes like the Tempest or the Corsair and Hellcat. that doesnt harm your speed/climb much, if at all !

very few planes in game are overrev in a power dive (full power, 100% pitch) - IIRC that are the Cr.42, G.50, Mc.200, Fw190A/F in manual mode, Fw190D/Ta152H in manual mode, the Brewsters(not sure about that , may have changed in a patch)


Fw190 in auto mode
Spitfire IX and VIII in auto mode
Bf109, Bf110,Do335,Ta152C in auto mode:
have a one lever system, if you control the throttle, the pitch is automaticly also controled


Bf109, Bf110,Do335,Ta152C in manual mode:
thats totaly different, here you control the propeller blade angle direclty ! no automatic will keep the rpm in a "good" condition. it brings you no benefit to use this manual settings anymore (there was a time ). so, dont bother it

the
Ki-27
J8A
TB-3s:
have fixed propellers, so nothing to control there




sure, others may have other experiences - but it fits for me.
