Hi Rusty,
How long did your static run with EWP only last?
I'm convinced from what you and Todd have done that I'm going to be able
to get my system to work with two WP136's. I've ordered a couple of
check valves with the expectation that I will be running the pumps in
parallel (the picture is a 1 1/2", but I'm getting a 3/4"). These
things are rated for 450 F at 125 psi. I don't know the opening
pressure, but there is just a little flap that has to swing out of the
way. I will have an AN12 running form each pump to the Mezarie 13B
adaptor, and an AN16 returning to both radiators. At least that's the
setup I will test. I sure hope it will work because otherwise I'm going
to have a mechanical nightmare trying to get a water pump and alternator
running off the side of the engine.
I'm hoping to have exhaust, intake, and cooling systems coming together
this month or early December.

Finally, I got a chance to test my EWP without the mechanical pump. I
removed the alternator belt, and tied the plane down for a static rpm
test. I then proceeded to stress test my battery, by cranking and
cranking without turning on the EC-2 (Doh!) Finally, the brain
kicked in, and I cranked the engine. It was much cooler than usual
today, about 70 rather than 85 or so like it's been recently. My
impression was that the EWP was doing a reasonably good job by itself.
It took quite a while to warm up enough to
make a full throttle run, and during that run, the water didn't seem
be heating much faster than normal. I would say that it probably WAS
heating faster than normal, but not at any sort of alarming rate. Lower power settings were just fine, and I have no doubt the EWP will
work as intended if I ever lose a belt on the mechanical pump. Unfortunately, (or fortunately, depending on how you look at it), I
couldn't tell any difference in static rpm between having he EWP only,
and the mechanical pump. Both measured 5960 static. This means I can
leave my system alone.
