Just got settled for the Night at our hotel in spearfish S.D.
Did about 550 plus miles today.

Tried my first shot at L.O.P.operation. How does 155-160kts cruise
at 10.7 gph sound? Found that the engine ran cooler and was
also smooth.

Have more good news for when I have a PC with A keyboard. this is my
tablet.

Should be either at Yellowstone tomorrow, or touring around the black
hills. -will be looking for crazy horse and Rushmore from
the air.

See ya.

Tim,

Wish I had known you were in the Hills. Could of
hooked up, got another look at your 10 and if you had
time you could have taken a look at ours and given us
some tips. Hope you are having a great trip.

Tim,
Great news about the LOP, I've done a lot of research and look forward to
using that method someday. One question, at what altitude did you achieve
these numbers?

Sounds like you're having a great trip, excellent motivation for the rest of
us.

Thanks,
Marcus

Question, You have a 6 cyl egt system with the chilton right. So what was the difference of temps on each cyl., were they say 50 degree of each other or 25. Which peaked first and how was the others at that point. Did you have one that was way out there  not as high or low and what was the fuel flow difference?
 
thanks
Pat

All are about within 50 Deg. or maybe better-
4 and 6 seem highest After peak.
Leaned to 50 LOP min today and put one to
Closer to 100

Chelton has nice indication of tempS

More to come.... I need a keyboard!

Hi Tim
If you are not running Gami injectors, you might want to get thier test sheet on comparing injectors inflight. I think you can download it from their web site. YOu start leaning slowly and check the temps on all six cylinders as you lean. You end up with a good idea on how each injector is doing. Not everyone need Gami's, but most do, inorder to get the temp spread close enough. I have run Gami's in my 210 for a long time. When you run lean of peak, you can up the power setting to compensate for the HP loss at lean of peak. You won't lose as much speed, and the engine likes it!!!! I plan to check mine as soon as I get it good and broken in and will put in Gami's if needed. With fuel costs, you can pay for a set of Gami's in no time.

I also ran Gami's injectors in my Baron and they worked great. It took my fuel flow down from around 32 gph to 26 gph, I had IO550's, but I did lose some speed in doing this.
 
I've ordered the Advanced Flight System 3400 from Stein and on Advanced Flight Systems web site there is an interesting article on flowing the nozzles. If you're interested, go to this web address http://www.mstewart.net/super8 and click on the bottom left where it says Flowing the nozzles. I think you'll find the write up interesting, if you're considering running lean of peak. I'm sure you all know that when running LOP you have to be very careful and really monitor what's going on with the temperatures.

Is that 210 running on Continental or Lycoming power? I have heard from the
Gami people that they are much more helpful on Continental engines than on
Lycomings. We have thought of them, but the IO-540 is so efficient already
that we haven't felt the need.

I am going to list some findings from personal research, but this is all IMHO and so on, so please take it as that and correct me where I might be wrong according to your research.
 
LOP can be dangerous at high power settings, where you have to be careful of temperatures so you don’t mess up your cylinders.  The beauty of GAMI’s in this situation is that it helps match the fuel flows to all 6 (in this case) cylinders so the temperatures run as close to each other as possible.  This way you are not running one cylinder too lean and possibly damaging it while at the same time running another too rich and wasting a bunch of fuel to cool the cylinder more than it needs to be.  When you are at a lower power setting, say 60%, however, the LOP operation is not as dangerous.  In fact, you can run as lean as the engine will allow without running rough.  Yes, you lose power, but you save a lot on fuel.  To fully take advantage of this feature, especially in the RV-10, the key is to fly high.  You can keep the throttle all the way in, and use altitude to lower your power setting.  For example, at 18,000 feet the IO-540 is probably running around 40% power, give or take.  At this altitude and this “power setting”, you can lean it right out and you get fuel burns as low as 6.5gph, while still getting good airspeeds, around 155-160 knots, because of the thin air.  You also have relatively cold air to keep the cylinders cool.  Sure, you may be able to get that type of fuel burn at 1,800 feet, but you would be very slow, which would defeat the purpose of the RV-10.  In that case you would be better off with a J3 (it can only fit 2 people, but it may be hard to find 4 people who want to go anywhere that slow anyway J ).  Again, GAMI’s might make a difference in this scenario, and it may be worth a try, if we can ever get around to doing it.  If somebody has them on their 540, please try some high-flying and let us know what you can get.
 
Has anybody else flown this high in a -10?  If so, what kind of numbers have you had?

Wayne, thanks for the link, It's great information.

There is an excellent white paper available for free (40 pg. pdf) on
Electronics International web site Titled;
/Leaning and diagnosing Engine Problems/.
http://www.buy-ei.com/The_Pilots_Manual_by_EI.htm

It's the best paper I've seen so far, explaining in detail what occurs
within an engine on each of the 4 strokes, and what the causes are of
bad things which can happen to an engine. It deals specifically w/
detonation (a risk in LOP operations). I highly recommend it for
reading, even if you're not planning on LOP operation. I learned a bunch
the 1st time through, and have a printed copy that I keep, in my
'continuing education' reference stack.
