4.11 and Engine Overheat

Both US and British manuals state 5500ft.

As long as you can fly the a/c as per book (and you certainly can as I described above), I don't see any problem.

Specific Engine flight chart Airplane Models F4U-1, FG-1, F3A-1 R-2800-8



Normal Rated (MAX. CONT.) 2550 RPM / 44" MAP / 7000' Critical Altitude WITH RAM / 5,500' Critical Altitude NO RAM / N Blower

Normal Rated (MAX. CONT.) 2550 RPM / 49.5" MAP / 19000' Critical Altitude WITH RAM / 16500' Critical Altitude NO RAM / L Blower

NOrmal Rated (MAX. CONT.) 2550 RPM / 49.5" MAP / 24000' Critical Altitude WITH RAM / 22000 Critical Altitude NO RAM / H Blower

Am I wrong thinking that WITH RAM is what the pre IL2 1946 4.11 engine performance was set to while IL2 1946 4.11 is using NO RAM engine performance. This applies to 4.12m as well?
Could you please explain to me what the difference between WITH RAM and NO RAM? How are each of these conditions acheived? Is WITH RAM the condition when the carburator inlet door is open creating a ram air effect and NO RAM the condition of the carburator inlet door being shut? In the game is it true that when we open/close the radiator this operates the cowl, coolant, oil cooler and carburator air intake flaps/doors simultaneously instead of individually like the real aircraft did?
Thanks in advance for the explanation whoever explains it.

Additional question. Takeoff Power Setting is 5 minutes maximum duration, Military Power Setting is 5 minutes maximum duration, War Emergency Power Settings is 5 minutes maximum duration. In the game we get an engine overheat warning when exceeding normal operating performance at various altitudes. Does the warning in the game come at the 5 minute max duration mark or does the warning come earlier than the 5 minute mark so you had better noted the time you went to military power or war emergency power?
