Tracy,
I am convinced.
I thought that the
coolant flowed around from the intake side to the spark plug side and that was
cold to hot side. Please straighten me out on how it flows and
etc..
Ed and
Mark,
I have the
Renesis. I expected that the EGT from the side port exhausts would be
cooler than the PP exhausts on the 13B and 20B? I think I expected about
13-1400 degrees with the difference going into the coolant.
Ernest,
Good idea but I am not
certain how difficult it would be to squeeze that heater hose shut. It is
pretty stiff. I could probably reduce the flow, but I would be concerned
about damage if I squeezed it completely shut.

One correction. You
are NOT bypassing the hot side of the engine (combustion chambers)
You ARE bypassing the radiator and putting the hottest coolant back into the
engine.
Install the valve!

it is flowing full

Naturally this water
is bypassing the hot side of the engine as well as
the radiator.
I would like some opinions as to what effect this might have on
my cooling
temperatures. Has anyone done this, then installed a valve
to shut off the
flow and seen the effect?
I have a valve, but didn't want
to put it in till I design the rest of the
heater system.
What say
ye?
Yesterday morning, OAT about 70, water temp about 170 when I took
the
active, climbed to about 205 getting to pattern altitude, then cooled
to
about 199 as I went around the pattern. I left of a little
sightseeing trip
got up to 2500 (low clouds) flew over the house, (the wife
heard me coming
and ran outside..so much for thinking it was quiet! She
said it sounds like
an airplane on steroids. I take that as a
complement)
The temp seemed pretty stable around 200, but it did climb to
210 one time
for a short period for no reason that I could figure then came
back down.
EGT I thought was pretty high, around 1600. Mixture about
two bars above
the midpoint.
