Hi All,
I had a very good cooling results on my other Lancair IO360 with ceramic coting of the inside and the outside of my exhaust.
I fly in South Africa where the outside temperatures are 100F and above .

I have an opportunity to do the same on my Lancair 4 TSIO550 Twin turbo 350hp.

Did any of you do that , do you think its a good idea

Regards Hans
