Hi there Steve. 
Do you live at the Everest base camp!
The highest peak in Western Australia is 4000ft and its 800miles to my North East.
I didn’t even know it was there till I looked it up just now.
I guess 99% of our land is flat with just a few hills.
Our greatest attraction is at altitude 0. Our beautiful beaches.

Thanks for the data. Even though your environment is so very different to mine its interesting.
How do you start with a scoop Coolant delta of ~8F. 
Looks like your coolant rad gets delta’s of 13-18F in flight.

I suppose I just won’t know how she will go till she flies.
I’m planning to measure pressures relative to static during that first flight.
I was thinking at each Exchanger face, and a few points around the cowl.
My chief concern will be exit area so looking for any positive pressure rise under the cowl.

Your flying and have married thinking with experience so any wisdom from you would be appreciated.

Steve,

Here is the flight data for the conditions under which the heat exchanger data was collected.  Three touch and go circuits were executed before climbing to an altitude of about 10500 ft.  The TAS is unstable due to the winds aloft and the proximity to mountainous terrain.
