So far, I have learned that I have hardly any (possibly
backwards!)airflow
thru the end of the oilcooler opposite the end where the
air comes in. I
will put a new duct on my list of things to do.

What is the pressure under the oil cooler relative to static pressure?

Paul Lamar


It is different in the two locations I tested.
So far all I have are relative readings with the tubes on top and bottom of
the cooler in two different locations. I have not tied the tester into my
static ports yet. It may give more meaningful readings that way, but will
require twice as many flight tests with tubes in different locations.

What are you doing next weekend? I am thinking of flying the 182 over and helping
you do some pressure measurements. I'll bring my new 2 foot water manometer.
You have a really interesting cooling arrangement and I am intensely curious.
Jerry if you can drive down and meet me in SZP you could come. Perhaps
Chuck would give you a ride. We could stop in Prescot and see Tom Parkes
turbo three rotor Lancair ES. Anybody else from So Cal want to go?
