Steve - if you are interested in testing cooling performance with the =
hole plugged up, can you use aluminum foil duct tape to temporarily =
cover that hole, then do your same test?

Hi Guys
Got back to the hangar today and thought some of you might like an =
update.

After fixing some small leaks in the cooling system we proceeded to test =
the cooling system.
OAT was only about 20C or 68F.  Engine coolant was already approx 140F =
after some testing with the cowls off.

Put the cowls back on for a stationary test - Course pitch and 2200RPM =
she took over 25mins for the H2O to get to 195F and Oil about 8F cooler =
when I shut it down.
Having some pitch on the Prop makes a big difference with the cooling.

I have no base comparison as I don=E2=80=99t know how other peoples =
setups compare but I came away a little optimistic that she might =
actually cool in the air.
She is retractable so presently on the ground she has one rather large =
hole in the bottom of the cowl.
What happens when that hole gets plugged is unknown, I=E2=80=99m hoping =
pressure in the cowl drops and cooling increases, but we=E2=80=99ll have =
to wait and see.

Engine ran silky smooth on B, less so on A, so Ive got some =
investigating to do.

Hoping next week to do a fine dynamic balance of the prop and maybe taxi =
her and see what that does to the cooling.
I=E2=80=99ve attached a frame from a movie I took today. (The prop looks =
pretty bent!)

Cheers
