oho Posted June 25, 2020 Share Posted June 25, 2020 how can i get optimal Power without overheating. Do you use radiant etc. change prop ipitch for cooling or is it just throttle and watching the temperature? Link to comment Share on other sites More sharing options...
razo+r Posted June 25, 2020 Share Posted June 25, 2020 The slower you go, the quicker the engine will overheat. So it's not just about engine settings, but also your flying. Link to comment Share on other sites More sharing options...
-0303- Posted June 25, 2020 Share Posted June 25, 2020 (edited) Besides throttle one can switch radiator Off (fully open) [A] toggle. I'll do that when oil temp exceeds 80. Don't exceed 85 says manual. Unfortunately to keep oil pressure below 120 I found one needs to keep oil temp near 80 at full throttle. Really whenever one applies any throttle oil pressure gets close to 120 it seems. Oil pressure should be between 60-120. I could have sworn oil temp was supposed to be 60-80 but reading manual now it says 20-80. Specifically manual says: Reliable motor acceleration is guaranteed when the coolant temperature is not lower than 60° C and oil temperature is not lower than 20° C.and I can't find "60" anywhere referring to oil temp.

DD_Fenrir Posted June 27, 2020 Share Posted June 27, 2020 (edited) Maximum (War Emergency) Power: +18lb boost @ 3,000 RPM - 5 minute limit Combat/Climb Power: +12lb boost @ 2,850 RPM - 1 hour limit Max Continuous Power: +7lb Boost @2650 RPM - no time restriction These all apply whilst you have enough airspeed to drive sufficient air through the radiators to provide the requisite cooling. As a rule stay above 160mph IAS (180 better). I never dogfight in WEP. Combat power is sufficient. WEP should only be used when you find yourself needing to disengage from a fight and you are being run down by e/a. Obeying these parameters I have never been obliged to open radiators manually to enforce cooling, or had a an engine failure due to overheating.

However, if ammo is expended and fuel is becoming a critical issue (as it often does in the dear ol' Spitty) there's only so long you can grind holes in the sky dodging your attacker(s). It's at this point when the e/a is at a high angle off I push to +18lb and 3000 RPM, dive if possible and extend as much as I can towards friendly lines, friendly a/c or just away from the hostiles. K-4s and D-9s will run you down sure, but if you break in good time, force an overshoot, it is entirely feasible to wash rinse and and repeat the process.. You can keep it up till they break off through boredom, frustration or the sudden appearance of your buddies, be they in the form of AAA or fighters. Or they follow you all the way home to your airfield in which case you hope their fuel reserves are as critical as yours! Link to comment Share on other sites More sharing options...

It's says 9 lb for climb. I notice now that manual states 12lb 1h and doesn't say 9 lb anywhere.
