I would have thought your boost setting was a more important factor in cooking the engine than your RPM. With a constant speed prop you could maintain 2800 RPM while using excessive boost - that would surely fry your engine. Would be good to know the full picture - boost / mixture settings and speed, oil and coolant temps during the climb. |

That's about what you find for the Merlin II engine. I prefer to run at 2600 because the sound is more comfortable. Danger on engine lifetime comes from overboost when it's available and max revs, however the engine should handle it, only resulting in shorter maintenance and ultimately lifetime, but that's currently beyond Cliffs of Dover. |

Perhaps next time you try it you could watch the oil and water temps carefully and record any excessive temps that occur during the climb. A recorded track would be even better. Cheers |

"I've also learned that it should'nt be the case since they are normally auto rich and auto lean so lean shall work better in theory."
Not really Auto lean is really only of use for cruising and has Max boost limitations associated with its use. Currently in game if run Boost cut out you need to push the mixture lever forward to AUTO lean to get smooth engine operation. This is of course totally wrong and should result in engine issues pretty darn quick. SPIT MKII Boost limitation in Auto lean is +4/2650 100 Octane or 2.25/2650 at 87 Octane. Spit MKI Boost Limitation in Auto Lean is +2.25/2600 87 Octane. Unless you are really interested in best fuel consumption then Auto Rich is all you should really need. |

AFAIK jf, the Merlin can handle 6.25 lbs/3000rpm only for 30 mins, before issues occur. However, as it is now, you are lucky if you can go 2800rpms without cooking your engine and that is in level flight.

Ive found if you apply a bit of common sense and watch your temperatures you can get by. Ive run with boostcut and water temp up to 120c and oil to 97c for about a couple minutes without failure but water needs to be mostly under 110c and oil 95c to avoid damage. With temps properly managed I have run boostcut continuously for 30mins without any noticeable damage.

Should be cross checked, but in my mind, it should handle that. But I really think that's side effects from inadvertant engine and flight model changes. They are not documented anywhere that I know and one has to try to see what is working and what is not. I used to read the historical manual, but what you find does'nt essentially apply to CoD. |

Boost and maybe mixture settings may be the culprit.
I havent flown the Hurri in the latest patch but the spit requires careful attention to RPM, Boost, Mixture and Prop Pitch to manage RPM/Boost, or it will fail after about 10mins of abuse. In particular I now have to manage mixture which I havent had to do before the patch. The Hurri maybe different but just something to consider. |

If it's modelled right, mixtures pulled back is rich, then it shall be ok. And when pushing away, the engine's rough under many conditions. I've also learned that it should'nt be the case since they are normally auto rich and auto lean so lean shall work better in theory. |
