Jerry, are you keeping track of OAT and oil temperatures to see numerically
what the effect of your inlet change has been?  I'd be very curious to see
the data.

Thanks!  Keep at it - all us northerners are counting on you!

I think you may be on to something Jerry.
I’m looking forward to a warm cabin this winter as I won’t be flying until
November at the earliest and I really don’t want to have to wait until
spring.

Keep posting those results!

Now as winter is at our door step here in Chicago.   We had snow on
Saturday. I have been trying a idea that seems to be
working out . I am in the early stages of testing this but so far I like
what I feel.  My thought is the Naca front heater scoop
is what many say is a ram air scoop. I think  is to large. So to keep it
short I am working on blocking off much of the scoop to see if I can get
more heat transfer by allowing the air to slow down and expand before being
used to heat the cabin. The first test I had almost
no air pushing through the air ducts. The second test had nice warm air  .
I have to do much more testing of this but I like the early results.
Has any one else tried this and if so what did you find.

First scoop

Second scoop
