The water manometer is proving it's worth. I cut out the louvers, built

a new exit duct

similar to the aluminum monstrosity that you built. I noticed on

climbout the great suction

at the rear that I had with the aluminum duct was no longer there. It

was less suction. Then

in cruise configuration, I actually had pressure at the front two exit

measuring points,

static pressure at the third, and a slight suction at the rear. So now I

have to put those

louvers back inside the exit duct????

I'm convinced that stock Mazda oil cooler form factor is just no good

for a tandem seat

airplane. Don't mount it longitudinally like I did, it just doesn't

work. It only works if

you can mount it face flat into the wind like it is in the car, or in a

side-by-side plane

like Ed Anderson's.

I think I will have to get a Fluidyne oil cooler with a more square form

factor, and put the

inlet and exit on the bottom of the strake.

I am going to build that finned oil pan. My exhaust system doesn't

radiate into anything. I

figure it can only help, and if it doesn't, it will still look cool.

Perry,
What about having two (in the tube set-up) similar to what has been shown on
here recently - would that do the trick or are you too limited on room.
