The cruising temperature should be 95ºC.

3000 rpm is fine for combat.

At +6¼ psi boost you need at least 2080 rpm to avoid detonation. This is important with 2 position props. You can't just change to coarse pitch at full throttle, because you're likely to go below the minimum rpm for your boost and break something. Therefore with a 2 position prop I throttle back to 0 boost before switching to coarse pitch.

Oil temperature should be 90ºC for cruising and 95ºC max.
weird..I have the pilots notes, and it says 120C for 30 min, and even 135 C for 5 minutes. Good to know about the minimum rpm though, thanks! Oil temperatures are always around 95, nothing I can do...can you achieve combat performanced with these limitations? or do you just cruise and do some sightseeing?
