Alttitude of the IO-375
Guys,
what is the highest you can fly the aircraft with the IO-375?
FL180, FL200?
I would like to fly the thing at FL200. Is that a reasonable proposition or is that just pushing the thing too far?
Regards,
Gus Bisbal

Why so high? I don't think there will be any problem running up there, you'll have to be careful coming down from such a high altitude so as to not shock cool the engine.

Why so high?
Because I want to be able to know if I can get above weather if needed when going over large bodies of water. And yeah thermal shock is an issue but I don't plan to decend any faster than about 500ft/m

In the US you need to be on an IFR flight plan with a full face O2 mask above 18k... yuk!

Gus, we were on the way to N.C. yesterday but we knew it would be dicey...lots of Cu building up. I scrolled the pointer of the 496 to the center of the red...."Tops 33,000' ". No way to top that, so we u-turned and went back.
Good luck,

+1. I don't know what the weather is like down under (does the rain go up?) but "topping" weather at 20K is a risky proposition. If you're just talking about layers, thats fine. However if you're thinking you're going to top any serious cumulus build ups, when you're up that high the build ups can easily out climb your aircraft with a moderate level of convective activity. You could find yourself in a very dangerous position very quickly up there. I've been in the mid 40's and seen storms that have anvil'd on top start building right past me (with about a 30 mile stand off).

One step at a time
Guys,
flight envelope, I want to know my flight envelope.
If I know what alttitude I can operate at then I know my options. I want to KNOW my options. Not "I am building a flight plan right now and am putting on my gloves so that I get ready to taxi out"
I am going to be going over the mountains in New Zealand they are at max FL130.
I would like to know how high I can go. This is an engine question not a flight practices question. That is a completely different issue.
PS. I have no problem with IFR/IMC with a mask. I prepare and practice for those missions and it is part of being a private pilot for me. Getting a -20C draft is more an issue for me actually over a 2 hour period. That affects my concentration but again this is a flight envelope question not a best practices question.

In that case, I don't think you'll have any problems getting up there and operating. The other issue you'll have to be careful of is exceeding Vne TAS on the way down. Other than that and the shock cooling... if your motor will get you up there I can't think of any other potential issues.
