I did keep provisions for a relatively easy conversion to a mechanical
pump in the event of failure of the EWP experiment, however due to time
constraints myself, I really just want to get a few necessary items taken care
of, then get it back to the airport and get back in the air. Besides I can
already hear the naysayers banging the anti-EWP drum, even if I did remove it
only for an experiment….I’d have to do it in secretJ

Hey, Todd. If I put any more items on my projects-to-do
list, I would have to ask the Man upstairs for a much longer extension
{:>). I would love to do more experimenting, but feel its time for the
"younger generation" to take over the reigns.
How are would it be to slap the mechanical pump back in your
installation - I mean its to cold to fly up there in the winter time anyhow

I think Ed is just trying
to egg me on, knowing the attachment I have to this subjectJ.
Referring
to Bob who reported marginal cooling with his EWP, it would have been nice to
know how the system would perform with a mechanical pump. I’m satisfied with
the performance of my Davis Craig EWP, even though it is somewhat marginal on
hot days during a 3 minute 2000fpm climbout with boost. But I doubt the
mechanical pump would do any better. I’d like to improve my cooling system,
starting with my hailstorm damaged evap cores, but I’m still committed to using
my EWP.
I guess
until we can get a true experimental minded type of guy who already has a
successful mechanical cooled system, to switch over to an EWP with no other
system modifications, then we will never really answer this question.
Gee Ed,
you sound bored... It’d be a great way to pass the summer?

I was just thumbing through a recent catalog from Summit Racing
and came across a couple of pages on electric water pumps. There has
always been a degree of interest (and some debate {:>)) regarding the use of
electric water pumps in aircraft.
Are you really that bored Ed? Maybe trying to stir up some
lively conversation, and tired of the same old fuse breaker topic :-)
I'm off to run the single rotor again, now that I've got
the RD-1C drive back on it. Don't tell anyone, but it's only got an
electric water pump :-0
