| Subject: | Re: Static System Assembly |
Mike,
Thanks for the McMaster part number on the cap. I just ordered two of them
along with enough "push to connect" parts to assemble the static plumbing.
You are right, Mike, these parts will make rebuilding the system far easier
and the sealing of small parts is now going to be a non-issue.
One other thing to add: If a push to connect T is installed in the static
line leading to the instruments, the transponder check will be simple to do.
This T could be permanently installed in the line passing through the rear
cockpit which makes it accessible while standing on the ground and reaching
over the canopy rail.
Thanks, Jerry

I am building an RV-7, and am installing the 180HP XP-360 engine with
an Airflow Performance FI system. I got the stock/standard oil cooler
in my firewall-forward package (Van's part "EA OIL COOLER II").
Reading comments from others my impression is that the -7s have a
tendency to run hot. I'm curious as to the impression other on the list
have about the best oil cooler to run with the setup I intend to install.
Right NOW is the time for me to make a decision, as I'm just starting
to do some baffle work.
Clearly, if I stick with the existing cooler I can baffle-mount it,
but if I switch to the larger Stewart/Warner style ol cooler (Van's
part "EA OIL COOLER 20006A") I'll need to firewall mount the cooler
and the baffle behind the #4 cylinder will need a fitting for four
inch SCAT hose.
So ... whats the collected wisdom on this issue, folks? Chime in if
you have experiences one way or the other. And ... thanks!

Dwight:
I just finished flying off my hours with an XP IO 360. I used the
factory mount and radiator mounted on the baffling behind # 4
cylinder. I started flying off my hours in October when daytime temps
here in SOCal were in the high nineties and low 100s. Oil temps did
not go above 220 and as the engine broke in were normally between 180
and 195. I did do some extra bracing as has been reported by others
to reduce vibration and avoid cracking of the cooler mount and
baffling. I really like the engine -- it did take some practice to
get used to hot starts with the Airflow FI induction system, but it
is easy once you get used to it.
best wishes

Jerry,
Sorry for butting-in but I sent some other -8 builders this pic of my
installation. I've had the airplane in Phoenix in 116 degree weather and
had no problems. (I live in Atlanta)
I hope this will be of some help. This shows the positech which didn't
work from the start, i.e., the first flight.
I replaced it with the S/W and have had no problems since.
I hope this will be of some help.
