Hi Guys

Ive finally got the engine (Renesis) and cowl complete on the Glasair.
Now without a prop I can run her (1500rpm, 90 deg F ambient) for about =
10 mins before water temps teach 200 deg F.
Hoping that with the prop she will keep her cool.

We have sought to protect the inner cowl surfaces from exhaust radiant =
heat and this appears to be functioning
however I=E2=80=99m surprised at the upper cowl external surface temps =
after shut down getting to hot to touch.
What are your experiences of cowl temps after shutdown?
If air-cooled engines run up to 400 deg F CHT=E2=80=99s how do they go?
I take it we all have glass cowls!
