Hi Jerry;
While the basic block is unchanged from those
pictures, I did modify the orientation of the hose nipples and upsized them for
1 1/4" hose when I added the coolant header tank and rerouted the hose runs for
a shorter and cleaner installation. I also moved the turbo coolant to the
coolant header tank and plugged this inlet as I felt the turbulence caused by a
flow return at this point may be somewhat restrictive. Also I believe I must
have had a dyslexic moment when I labelled those pics as it is "RTD", not
"RDT".
Another point that I'd like to bring up right
now is hose sizes. I often hear the statement that a car is only run on 30%
power on average and yet the auto manufactures use a minimum of 1 1/4" hoses for
coolant. But in our airplanes builders commonly use much smaller hoses &
fittings usually in order to use AN fittings of which I believe AN16 is the
largest (correct me if I'm wrong) and is only 3/4". I don't understand this
reasoning. I used 1 1/4" hoses up to the "T" where the rads are plumbed in
parallel, where I step it down to 2 -1"hoses. Even the "T's" were made with
minimum restriction in mind. If we have a higher power demand from the engine
(which is always used as a reason not to use EWP's), then why restrict it's
coolant flow?

typing)
Thanks Todd, I am pretty sure I will follow your example. Could you
provide a verbal description of the adaptor block? Thanks, Jerry
Hi
Jerry,
Here's a
link to the archived message Todd sent when he made the adapter. It's
got a description, and several pics.
Meziere
also makes two different adapters for the rotary. See
attached.
Cheers,
Rusty
