I have an andair duplex valve and will be returning the purge fuel back to
the same tank...otherwise, you need to placard for selecting the same fuel
side that your return is plumbed to or risk pumping it overboard.
My purge valve is mounted 'lay-down' style insteda of between the cylinders
as I am using a sam james plenum. Contact AirflowPerformance - they can
swap out the purge valve if you need to avoid cowl interference issues.

I'd like to get feedback from flying RV-10's as well, since it is as much a question of how good the cooling design is on the -10 as it is a general discussion of engines and ignitions. The general discussion is pretty well covered in online documents from the CAFE foundation (http://cafefoundation.org/v1/aprs/ignition1.pdf ), where in their test platform CHTs went up enough to cause them to have to modify the cowl outlets of their test plane. The AVWEB discussion of the LASAR system ( http://avweb.com/news/reviews/182489-1.html ) notes CHTs about 30 degrees higher than with stock ignition but concludes it isn't a problem if the engine is still in the green.
Some airframes are pretty famous for being tightly cowled and having CHTs as the
limiting parameter on hot day climbouts. Some its no biggee. Just would like
some anecdotes about the early RV10 experience on this. Not trying to cause
ignition of any flame wars (pun intended).

What fuel pressure should I see for the electric and/or the
engine fuel pump. The Lycoming operators manual talks abour 40 being
the max, but when I run the electric pump I get 6 and when the engine is
running at idle, it is also around 6 with the electric one off. Does
this sound normal for an Injected IO-540?

That is an angle valve engine so it won't work. To conserve bandwidth
I'll send you a spreadsheet I made a long time ago with the parallel
valve engines listed.

You should see about 25 or more (at least with the electric pump). I
do not remember the engine pump pressure. Something in your system
does not add up.

I had the same question a while back. I contacted Airflow
Performance about it. Here is a copy & pasted email from them,
Randy...............................
We manufacture a boost pump to be used with fuel injected
engines. P/N 3090050 $375.00. The pump is 12 VDC, fuel pressure is 25-30
PSI, flow capacity is 32 GPH @ 30 PSI, requires a 7-10 amp breaker.
You fuel injection system (Bendix) requires 22-35 PSI to operate. If you
have a diaphragm engine driven pump (P/N LW15473) this pump should produce
22-26 PSI. If you engine has a vane pump it should be set to 26-35 PSI.

50 pounds? That's it? Is this the best the RV-10 list can do?
I am willing to say that the Hartzell 80" diameter blended airfoil propeller
and spinner assembly weighs at least 65 pounds ready to bolt onto the engine.
The Hartzell 72" diameter propeller and spinner assy with 7666-4 blades
weighs 56 pounds.
The Hartzell 80" diameter propeller and spinner assy weighs 66 pounds.
I would suggest that the blended airfoil blades are not significantly
lighter than the standard aluminum blades.
Is someone on the RV-10 list actually willing to weigh their Hartzell
blended airfoil propeller and spinner assembly to provide a REAL weight?

Let me retract, the IO-540 A1A5 cannot be used in the RV-10, but the
0-540 A1A5 can. The IO is an angle head, the 0 is a parallel head

Ray,
Metered fuel pressure downstream of the servo is around 5 psi with little if
any change when the electric pump comes on.
If you measure fuel pressure just downstream of the mechanical pump, before
the servo, you should be able to see the electric pump boost the pressure to
30-40 psi. That's how you know it's working. The mechanical pump alone
should keep it around 20-30 psi. 6 psi is about right for a carbureted
engine. Carbureted engines use a lower pressure mechanical fuel pump
compared to injected engines.

According to my research, it should not be a problem. I think only the K
models are angle valve, which would not work. Everything else should be
parallel valve. The only problem you may run into is the mount ears, but
those can be swapped out. There is a guy on the list who has a set to sell
also. According to Allen Barrett, all parallel valve engine are the same
size with a few minor variations, which would mainly come into play on
weight (minor) and fitting the baffles (trimming in different places and to
different extents).

What fuel pressure should I see for the electric and/or the
engine fuel pump. The Lycoming operators manual talks abour 40 being
the max, but when I run the electric pump I get 6 and when the engine is
running at idle, it is also around 6 with the electric one off. Does
this sound normal for an Injected IO-540?

Thanks for all the replies. I bought the electric boost pump
directly from Van's for the fuel injected engines. My fuel system is
per Van's exactly for the fuel injected engine. This is why I can't
explain the 6 psi from my Dynon Engine monitor when the electric boost
pump is running. I will check the engine driven fuel pump as well
tonight. But I can't believe that I have the wrong electric and engine
driven pump, because both of them only register 6 psi on the Dynon.
Thank You

Ray,
Metered fuel pressure downstream of the servo is around 5 psi with
little if
any change when the electric pump comes on.
If you measure fuel pressure just downstream of the mechanical pump,
before
the servo, you should be able to see the electric pump boost the
pressure to
30-40 psi. That's how you know it's working. The mechanical pump alone
should keep it around 20-30 psi. 6 psi is about right for a carbureted
engine. Carbureted engines use a lower pressure mechanical fuel pump
compared to injected engines.

I've read on the RV list about two months ago ... someone experienced the
same results ... about 6 PSI with a mechanical pump that should put out the
higher pressure for injected engines. This pump had the wrong P/N on it.
It was a low pressure pump with a high pressure P/N. Can't trust anything
anymore!

By the way, tachometer may be the same thing. We were only getting about
2,000 rpm I think on the reading when we tested it with a visual tachometer
and found that it was right at red-line. Make sure you check the settings
for all of the different probes, especially if you are seeing something odd
like that.

Even if the engine is an angle head engine as a core, it can be changed/
converted to a parallel head. Although it is pretty expensive to do,
several have been changed over. Push rods, tubes, inter-cylinder
baffles, sumps, etc, are the major changes. Some angle head engines are
more costly than others to convert, particularly the 'up exhaust'
engines because of the angle of the tappet body openings. These cases
will need to be converted, required weld and re-machining. It's a matter
of economics. Get the core for the right price and it may be feasible.
Pay the premium for the core and it may not be worth the cost.

According to my research, it should not be a problem. I think only the
K
models are angle valve, which would not work. Everything else should be
parallel valve. The only problem you may run into is the mount ears,
but
those can be swapped out. There is a guy on the list who has a set to
sell
also. According to Allen Barrett, all parallel valve engine are the
same
size with a few minor variations, which would mainly come into play on
weight (minor) and fitting the baffles (trimming in different places and
to
different extents).

I just found this on Dynon's sites as well. I will have to
check tonight, but I suspect I have mine set for Type 1 when it should
be type 2. This makes sense because the engine runs fine and the
builder (America's Aircraft Engines) ran the engine for over an hour at
75% power.

should keep it around 20-30 psi. 6 psi is about right for a carbureted
engine. Carbureted engines use a lower pressure mechanical fuel pump
compared to injected engines.

What fuel pressure should I see for the electric and/or the
engine
fuel pump. The Lycoming operators manual talks abour 40 being the max,
but
when I run the electric pump I get 6 and when the engine is running at
idle,
it is also around 6 with the electric one off. Does this sound normal

an Injected IO-540?

I had the same question a while back. I contacted Airflow
Performance about it. Here is a copy & pasted email from them,
Randy...............................
We manufacture a boost pump to be used with fuel injected
engines. P/N 3090050 $375.00. The pump is 12 VDC, fuel pressure is
25-30
PSI, flow capacity is 32 GPH @ 30 PSI, requires a 7-10 amp breaker.
You fuel injection system (Bendix) requires 22-35 PSI to operate. If
you have a diaphragm engine driven pump (P/N LW15473) this pump should
produce
22-26 PSI. If you engine has a vane pump it should be set to 26-35 PSI.

Just to add to the diagnosis... You will actually hear the
electric fuel pump spin up and as it builds pressure you can
hear it. So if you're pressure is always 6, but you hear
the pump working harder, you know it's in the gauge.
You could always stick a mechanical gauge in the
threaded sensor thing if you had to. Everyone's comments
are right though, you should see much more pressure. I'm
in the mid 20's without boost on.

50 pounds? That's it? Is this the best the RV-10 list can do?
I am willing to say that the Hartzell 80" diameter blended airfoil
propeller
and spinner assembly weighs at least 65 pounds ready to bolt onto the
engine.
The Hartzell 72" diameter propeller and spinner assy with 7666-4 blades
weighs 56 pounds.
The Hartzell 80" diameter propeller and spinner assy weighs 66 pounds.
I would suggest that the blended airfoil blades are not significantly
lighter than the standard aluminum blades.
Is someone on the RV-10 list actually willing to weigh their Hartzell
blended airfoil propeller and spinner assembly to provide a REAL weight?

I run the Airflow Performance on my RV-8A. I use the purge valve for engine
shut down, but it's main function is to eliminate vapor lock in the spider
for hot starts (never had to do this - 250 hrs so far).
I have the purge line plumbed back to one tank. Considering the very
infrequent use for purging, and that purge volume is only a few ounces, they
is no need for a duplex fuel valve.

I have an andair duplex valve and will be returning the purge fuel back to
the same tank...otherwise, you need to placard for selecting the same fuel
side that your return is plumbed to or risk pumping it overboard.
My purge valve is mounted 'lay-down' style insteda of between the cylinders
as I am using a sam james plenum. Contact AirflowPerformance - they can
swap out the purge valve if you need to avoid cowl interference issues.

Lights should be planned for when getting ready to start the wings.
There
are a number of different options, some of which require cutting the
wing
leading edge and things like that.
Auto-pilot can be done whenever, but the servos are a little easier to
install before the wing is closed up (although closing up the wing is
harder
with the servo in).
AOA should also be worked on with the wing.
Stuff can be done any time, but it wouldn=92t hurt to at least look into
the
installation and see if it would be easier before closing up the stuff
section. :-)
I don=92t know if you can get the QB fuse before the QB wings. To get
the QB
fuse, you will have to have the wing center sections sent to the
Phillipines
to be assembled into the fuse.
Antennas can all be installed after the plane is assembled, but deciding
where to locate them so you can get to the place is a good idea,
including
running conduit or snap-busings (or at least holes for snap bushings).
If
they are going to go in a closed-off area, then you will want to cut the
holes and install nutplates before closing off that area (ie. Tim Olson
installed his COM antennas under the rear seat floor, which requires
nutplates to be installed in the skin so you can remove the antenna from
underneath the airplane and then fish the cable out from there).
In short, most things can be done after the airframe is done, but a lot
of
things, especially things that require modifications to structures or
skins,
would be at least good to plan for ahead of time (ie. It is a good idea
to
install a Pitot mount bracket when building the wings before riveting
the
bottom skins, although it is possible to do it after). Wiring can be
done
after the plane is done, but conduits should be run ahead of time at
least.
The more different steps you look into ahead of time, especially looking
at
installation instructions, the more organized you will be.
Hope this helps.

Do the QB wings then the Fuse. If you can afford the cash flow and you
have the space, get both at the same time to save on the shipping cost
and consider using Partain. Currently Vans shows a 16 week lead time
for the QB kit.
Options for the Empennage are few mostly static ports and cable fairings
which could be done easier now rather than later (I still have to
complete those 2 tasks). Also, if you know it you are going to put 2
batteries in the tail cone you could make that mod early, but it could
be done later.
For the wings, fuel level sensors, wire routing (conduit or grommets),
lighting, AOA and heated pitot tube should be done during the build.
Autopilot servo, Archer nav antennas and wing mounted magnetometers
could be done later but easier during the build.
Fuselage options and modifications is where the real fun starts.

The Ops Manual I have lists:
inlet to fuel pump min -2 max 35
inlet to fuel injector min 14 max 45 min at idle 12
I think you should see something like 25 psi or so in normal operation.
AirFlow Perfomance recommends a boost pump setting a few psi higher than the
engine pump pressure to verify its operation on the fuel pressure gauge.
It sounds like you may have a gauge or pressure sensor for a carbureted
engine.
