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?

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
