A stock parallel valve 360 should flow at around 16 - 18 gph at full
throttle. I think you need to calibrate your fuel flow gauge if it is
showing 20 gph at only 2500 and 25", and at 4500' Would only expect about 15
gph at those numbers.
Mine flows about 16 gph at 2600 rpm about 500 MSL on climb out. Highest I've
seen is 18 during initial climb and lowering the nose a bit to get the rpm
to 2700.
If your EGTs and CHTs are too hot on climb out, you should check your carb
main jet spec. You will want the 10-4164-1 version. If you have the 10-3878,
or other, you could be running too lean at full throttle.

Hi Craig,
I'm still home sick for Alaska, would like to visit Alaska again in 2012
with my newly built airplane.
I got 7 hours on my new plane/new engine now, still breaking in the Engine,
the CHT/EGT run hot in Southern California.
My Engine is 0-360 A1A, when run at 25" MP/2500 RPM/mixture full rich @
4500 feet, the fuel flow exceeds 20 gal/hour, I'm new to this fuel flow
gauge, does it sound normal in this configuration? I have Dynon Skyview duel
screen EFIS.
So glad you are flying, we are pretty much on the same flight test stage.

Hi All,
I have almost 15 hrs on the plane now and several people have asked about
numbers. As far as temps, not sure how much good the numbers would do you
because it's so cool up here but....I've been flying in the 55-60 degree
range. In a long climb (2 min) about 85% power my oil temp was 225 once. I
have an oil cooler with a air shut-off and it was closed. Generally the oil
temp's been running about 210-215. CHT's are in the mid 300's and they stay
there. I can't seem to reduce temps enough to worry about shock cooling
during descents. Today I was flying at 90 mph at 3500' and had it leaned to
7.9 gpm with EGTS at 1380ish. If I don't lean, the 0360 drinks lots of fuel!
Except for T offs and landings I plan on leaning early and often!
If you noticed, my cowl is modified and has larger air inlets than the
stock speed cowl. I haven't really tried anything full performance
yet...being cautious and a little nervous. I have seen 1800 fpm with power
to spare and I find my self not using full throttle on take offs because
it's just not necessary, Probably a bad idea. I have to trim a lot. The
electric trim is slow to act and I over trim. Stalls are at 46 mph no flaps,
power off and 43 with two notches. I only built it with two notches but I'm
planning on adding a third. I haven't put the VG's on yet...I want to see
what difference they make once I'm used to the plane as it is.
The fastest I've flown so far is 115 mph. In the pattern I have to reduce
rpms to about 1250-1300 to get it to start losing altitude--not the 1500 or
so I was used to to. Once it gets to about 55-60 with 2 notches it has a
fast sink rate! I've found myself behind the power curve several times
during base and final and luckily the 180 horses easily fixes that. Still
learning.
It's an incredible feeling flying something I've built. Can't really put
it to words. Everyone, keep it up! Craig
BTW, Deb and I were at the Reno air races and near as I can tell from the
videos and photos we were sitting approximately 75' from the place where the
P51 hit. We were in the stands and had watched every race and decided to
leave early that day to beat the crowds. Makes you think!
