Brian,
I do not want to recommend for or against exhaust wrapping, because I have no experience with it, but my quick comment is this:
I would rather not reduce the air cooling of the exhaust pipes. Have you seen the photo from Rotax’ engine test bed, at max take-off condition? Frightening, if you did not know that it is designed to take it: The exhaust pipes are literally glowing red!
After I saw this, I always think about it at lift-off and reduce to climb setting as soon as it is safe.
My personal view is therefore to reduce the radiation that hits the carbs and rubber hoses as much as possible, rather than trying to prevent the heat from escaping its source. Shielding the carbs and the hoses has only positive effects, and weighs very little.
Regards
Svein

I agree Sven,
there is also the problem of wear and tear of the wrapping. We used to find it shed fibres and dust into the engine bay which is not very good. There's probably too much low frequency vibration.

Graham,
The modern stuff does not do that, but is very expensive. It is interesting that the LAA approves it on some Rotax 912 installations.

Hi Brian
maybe I should do it on my Lycoming. Plenty of heat under that cowling. The exhaust extraction works well though.

Not yet, I just sent off the application for engine mod. Then final inspection and apply for test flying.
