No; my plumbing is all done.  In fact, I also have 2 Wiggins couplers
I'd like to sell; how about $20 each - special holiday bargain.  These
are fi-i-i-ne pieces of work.  Just didn't work out in my setup.

Al, I am in the process of plumbing the dyno engine and I would like

to see more pictures of what you have done. Can you back off a bit and
take
a larger picture of this? I can't quite figure out what is going one
here.<<

I have two radiators, one in the cowl, one in the wing root.  The first
photo is with the engine off, viewed from the firewall side, which shows
the in-cowl rad on the right, and connections to the wing-root rad on
the left. The small connector tube over by the in-cowl rad exit line is
the heater return.  System air bleed at the top at the pump outlet.

The vertical connector on the inlet side (just in front of the oil
injector pump) connects to the coolant fill and overflow bottles that
are mounted on the firewall, and shown in the second photo.  The fill
bottle on the left connects to the line to the pump inlet at the bottom.
The two connectors at the sides are air bleed lines from each radiator.
The fill bottle has a 24# cap that bleeds off into the bottom of the
overflow (expansion) bottle.  This bottle has a 15# cap, which can bleed
off overboard, and will normally contain about 1/2 to 1 qt of air.  It
has a low-level warning switch in the bottom.

You can play some mind games about the dynamics of the system under
various conditions; but the concept is to maintain positive pressure at
the pump inlet side even after in-flight power reduction and/or coolant
temp drop; and have immediate full 24 psi pressure when putting power
on.  The other 2 photos show how all this tucks in, but you've seen
those before.

BTW when is a good time to drive the RX8 down and see your project?

After the holiday commotion would be good.  Hope to finish the custom
cowl and control sytem work, and get the engine back on in a couple of
weeks.  Weekdays after about noon or a Saturday - let me know.  It may
cost you a ride in the RX8 :).  If you want to fly over LA, I could pick
you up at either Oceanside or Fallbrook, either about 20 minutes away.
