Cooling

[Walter Klatt]

There has been much discussion in the past on this list about 0320 cooling
with the slower amphibs and the fibreglass speed cowl on the Rebel. I did
some work on my exit as per recommendations from this group last Fall, and
thought I had the problem licked. However, now with the hot summer days
(over 30 C a week ago here on the wet coast), I am still not satisfied. I
can't climb at full throttle for more than about 3 minutes before #3 CHT
gets up to 450 and I have to back off and level out for awhile before
resuming climb. Cruise is about 425 on a hot day, and down to about 380 when
it is cool, like a few months ago.

Wayne, I saw on your website a picture of GCYP (Howard's I believe), and it
looked like it had a big shrouded exit on the bottom of the cowl. Do you
have any close-up pictures of that? While I have a big hole and deflector
there for mine, I don't have it extended to the back of the firewall and
don't have lips on it right now either.

Also, I remember you saying that Howard was using a finer pitch Sensenich 2
blader which might have some effect too. I am still running the 3 blade Warp
with the UHS fibreglass spinner. The spinner is slightly smaller than the
cowl, and perhaps this is causing some turbulence at the inlets.

Anyway, I am determined to get this problem licked once and for all now that
summer is here. Any help and ideas from anyone on this would be greatly
appreciated. Thanks.

Walter

Now if you had of asked that question last night I could have taken my
digital camera (and a tape measure) with me to the Canada Day Celebrations
at Little Lake park and taken some shots of Howard's cowling exit, seeing I
was already wading around in the water for half the day (catching and
launching aircraft around all the swimmers that were trying to beat the
heat).

We will be up to Howard's on Thursday afternoon, for a "USA" Celebration
BBQ, and I will get you some shots then (if I remember). Our current plan
though is to head North from his place, with the motorhome, and we won't be
back until approximately next Wednesday. Mind you I don't have much faith in
that plan going through as that is only if Leah gets a clean bill of health
to travel, after her Dr. visit tomorrow, and I really have my doubts that's
going to happen.

Uploaded 4 pictures to Rebel section (or new for now). 2 of the cowling and
2 of the aircraft sitting on Howard's "air lift" to show you what everyone
is building towards in their garages.

The cowling outlet is the original width as supplied by MAM but opened to 4
1/4" before the lip, with the lip dropping another 3/4" to create some draw.
Howard also did "shark" gills below each heat shroud on the HP exhaust
hoping it would draw some heat out of there as well. He also has the air
inlets smoothed out at the top, so the air doesn't turbulate when it comes
in. He told me he was running about 380F cylinders temps in cruise on Canada
Day and it was 35C (45 with Humidex) He says he can still make her hit 500F
in a full power climb out though, if he keeps it up for any length of time!
Howard has an electronic engine monitor that covers all 4 CHT's and 4 EGT's.
The CHT probes are the thread in bayonets in the bottom of each cylinder.

There is also the "easy way" to get air flow out of the cowling, as I did
with Bob P's Rebel, and that is to simply cut out the entire area of the
lower cowling from one side of the exhaust pipe to the other pipe, forward
to just behind the carb heat dump pipe. Bob seems happy with his
temperatures and even complains his oil temp is too low, which is rare on a
Rebel with the speed cowling.

Thanks Wayne, those pictures are most helpful. I just back from a few days
of flying in 30+ heat, and always with a big load, so my engine temps were
near the limits all the time. Also, I badly need those window vents, as
cabin temps were also over limit. Anyway, had a great time on and in the
water, so really shouldn't complain when we get hot weather out here on the
coast.

One thing I noticed from the pictures, is that the bottom of the main
opening comes past the firewall. I think this helps a lot suck out air. I
initially did what you suggested with Bob P's cowl, and had the opening
starting forward from the carb down pipe, and it worked OK on wheels, but
now with floats it was completely unacceptable. I then extended the bottom
opening back a little further and it helped some, but I see from Howard's
that I should extend it even further.

Now I just need some time to do all this. I am back to work next week, and
don't want to be working on my plane on the weekends if flying weather is
good.

Again, thanks, I definitely have some more ideas and work that I can do to
mine now.

Glad the pics help! Forgot to take a picture of the window vent
installation, but as I said the CC3251's are the way to go as they sit flush
when closed and even if you forget them and swing the window down they push
in on their own.

Will take my camera to our RAA Northern Regional Flyin this weekend and if
Howard comes in I will get you a picture of location/installation.

Available from:
ACS = $7.85/pr
Wicks = $ 8.96/pr
Wagero = $13.65/pr (of course where I just bought 3 sets from, before I
checked pricing elsewhere!!)

Since ACS was at Arlington, I just picked up 2 sets. I should have read
Wayne's note more carefully, as I didn't realize you actually got two in a
package, and didn't open it until I got home, so now I have an extra pair.

I see where placement could be very important, though, as I want them so
they will blow on my upper body and face. They don't give you much for
instructions either, so also have to figure out exactly how they are
supposed to work.

Now if you had of asked that question last night I could have taken my
digital camera (and a tape measure) with me to the Canada Day

Celebrations

at Little Lake park and taken some shots of Howard's cowling exit,

seeing

I

was already wading around in the water for half the day (catching and
launching aircraft around all the swimmers that were trying to beat the
heat).

We will be up to Howard's on Thursday afternoon, for a "USA" Celebration
BBQ, and I will get you some shots then (if I remember). Our current

plan

though is to head North from his place, with the motorhome, and we won't

be

back until approximately next Wednesday. Mind you I don't have much

faith

in

that plan going through as that is only if Leah gets a clean bill of

health

to travel, after her Dr. visit tomorrow, and I really have my doubts

that's

going to happen.

There has been much discussion in the past on this list about 0320

cooling

with the slower amphibs and the fibreglass speed cowl on the Rebel. I

did

some work on my exit as per recommendations from this group last Fall,

and

thought I had the problem licked. However, now with the hot summer

days

(over 30 C a week ago here on the wet coast), I am still not

satisfied.

I

can't climb at full throttle for more than about 3 minutes before #3

CHT

gets up to 450 and I have to back off and level out for awhile before
resuming climb. Cruise is about 425 on a hot day, and down to about

380

when

it is cool, like a few months ago.

Wayne, I saw on your website a picture of GCYP (Howard's I believe),

and

it

looked like it had a big shrouded exit on the bottom of the cowl. Do

you

have any close-up pictures of that? While I have a big hole and

deflector

there for mine, I don't have it extended to the back of the firewall

and

don't have lips on it right now either.

Also, I remember you saying that Howard was using a finer pitch

Sensenich

2

blader which might have some effect too. I am still running the 3

blade

Warp

with the UHS fibreglass spinner. The spinner is slightly smaller than

the

cowl, and perhaps this is causing some turbulence at the inlets.

Anyway, I am determined to get this problem licked once and for all

now

that

summer is here. Any help and ideas from anyone on this would be

greatly

appreciated. Thanks.

Walter

Since ACS was at Arlington, I just picked up 2 sets. I should have read
Wayne's note more carefully, as I didn't realize you actually got two in a
package, and didn't open it until I got home, so now I have an extra pair.

I see where placement could be very important, though, as I want them so
they will blow on my upper body and face. They don't give you much for
instructions either, so also have to figure out exactly how they are
supposed to work.

Hi, Ian. I was going to offer them to one of the local builders here where I
live. I believe you are from down under, so not sure what shipping would be.
Unlike most aircraft parts, these are very inexpensive at 7.85 US from
Aircraft Spruce. I don't know what your local sources are, but you can order
them directly through the web from if you like. Here is the web page:

http://www.aircraftspruce.com/main.html

Go to the Online Catalogue section and use their search for CC3251, and you
can complete the order from there.

Thanks for asking and good luck.

Walter

Is it a 400 or 360? Murphy's 360 ran real cool. Ron Kakeldey's 400 runs real
hot with the same cowl but we have not flown it since October so will see
what happens after following some of Kevin Kimball's ideas. The acro guys
say the 400's all run hot but they don't seem to care. It may be fine with
US oil in them - if you compare to the P & W 985 it's not so hot.

Moose flyers,
We have our new Moose flying. First flights always bring up interesting
issues-- you will note I said issues, not problems!
We used Murphy's cowling. We are experiencing high CHT. Is anyone out
there who uses the Murphy cowl having the same "issue"? If so, how are
you dealing with it?

Hi Steve,
It's a 360. We've only flown it twice for a total of 1.2 hours. We will
fly again soon and develop more data before we get too concerned. But I am
interested in what other Moose flyers are experiencing using the MAM cowl.
Thanks for your input.
