The important point is that Rusty likes to do it the hard way
:) I think that he firmly believes that "experimental" needs to be
followed to the letter. Why benefit from other's results when you can do
the experiment yourself :)
Now wait just a minute
:-)
While some of the above
is clearly true, I had very good reason to try the evap core, and it was based
on Tracy's results. He recently mentioned that he never goes
over 210 degrees for oil, but he didn't mention that his SOP is to reduce
power almost immediately after takeoff. If I'm not mistaken, he did
this with his B drive also, to keep from overheating. He also climbs at
130 mph or so. With my evap core, I could climb forever at 90 mph without
exceeding 200 degrees when I had the B drive. It's only now that I'm
making more power that it becomes a limitation. Tracy's an
efficiency freak <G>, so he's willing to give up some extended climb
performance to reduce cooling drag in cruise. My philosophy is that I want
to be able to use all the power, all the time, without overheating.
So if you want better oil cooler
performance, what do you use. Let's see, what is Tracy putting on
his 3 rotor RV-8 project. Last I heard, it was an evap core
:-)
I didn't get my test fitting in time to
check the pressure at the engine outlet, so that test will wait until later
this week, assuming Ivan makes that a moot point. In
thinking about oil cooling options, I'd still like to have a water to oil
cooler, but I'd have to make the 3rd evap core water also, and also add the
new heat exchanger. Unfortunately, that would add too much
weight.
As for Ivan, it seems John's anti-hurricane
mojo is more powerful than mine at the moment. I seem to be
getting closer and closer to the center of prediction with every
report. It's almost certain that it will hit here, and destroy my hanger,
since I now have the new Slingshot in there also. Of course they both
have liability coverage. It's still way too early to worry about
that.
