OK guys, now that I've got
the silly cooling stuff out of my system for now, I'm looking at a custom
radiator. It's a little too soon to be able to finalize the sizing, but it
looks like I'll end up having an 18 X 18.5 X 2.5 core, with tanks fore and
aft. This will be an all aluminum, two row, 1" tube
core.
My current question, is
about oil/water heat exchangers. It seems that I've read where someone
tried this, and gave up on it, but I can't think of who that was, or how hard
they tried to make it work. In other words, did they just try an
existing auto trans cooler, or did they have something special
built. Does anyone know any specifics?
I can have an engine oil
heat exchanger installed in the radiator pretty easily, but of course it's
impossible to say if it would do the job. The Howe racing folks say they
feel the exchanger is better than what you would find in a stock radiator, and
that racing folks use them without any problems. Since rotary
engines put more of a demand on an oil cooler, I'm thinking of having two of their exchangers added to my
radiator. Unfortunately, both won't fit in one tank, so I'd have to put
one in the inlet tank, and one in the outlet tank. Strange as this sounds
(Hey, I heard that <G>), it would give me the following options in order
of effectiveness:
- use neither
exchanger
- use the one in the inlet
tank only
- use the one in the outlet
tank only
- use both plumbed in
series (technically two options here, but I'd figure to plumb to inlet, then
outlet tank)
- use both plumbed in
parallel
Do you think this could
work, or am I one wacky idea away from being voted out of the group
:-)

PS- I played with the
Henrob torch some more yesterday, and managed to turn some cast aluminum into
slag. Sure it was fun, but not the original goal. Proper rods, flux,
and instructional videos are now on order :-)
