My guess on the chart is that I was somewhere between 80-85% manual shows at 5000 (vs my 5500) and 2600rpm a MP of 25" 85% at 12.0GPH. True airspeed in table is191@2575#

My Pilot Manual shows at 7500 feet and 9.9GPH is 68%BHP and 135BHP.

Yup, that makes sense. The wonky readings were based on having initially set at 7500 prior to decent. I will look for the data at altitudes. Definitely did NOT redo lean-find prior to fuel flow increase. Thanks Tommy.

IO360A1A in front of a 66 M20E. Ram Air OPEN. My Owners manual gives following at 2500RPM: At 25.0MP BHP is 163 and 82%BHP with a flow of 11.5GPH. I have a responder saying "you were not LOP" at 9.5GPH... Anybody have charts with altitudes that show numbers at Peak and 100ROP? I would be interested in seeing that.

No RPM increase. I descended from 7500 LOP to 5500'. Ground speed increased with fuel flow by 20 knots. When I dropped down to 3500 feet I reduced fuel flow and throttle. My indications were regarding my increase in Fuel flow and indicated LOP on all cylinders on my G3. No, I did not re establish peak and LOP at 10-15 PRIOR to increasing fuel flow at 5500'. So, unless I reestablish Peak the outputs are entirely erroneous on the G3? I have two fuel flows. One on G3 and also an EI fuel flow. They are VERY close on their reading so don't think fuel flow is "off" on transducer. Yes, everybody I completely understand I was NOT LOP with the increase in fuel flow. Just wondering about indications on the G3. Learning here. Yes, I normally fly at 7500.

Return flight after bird hunting at in-laws cottages Friday and Saturday. Had wife and two English Pointers on board. Had a second in my ownership. Rough Mag. Had to work it a couple minutes to get the plug un-fouled. I am an aggressive ground leaner. Who knows? Maybe a plug is on the way out? Stayed low as a wind out of the south was blocking speed. Level at 4500. No chop. Listening to #1's (no name songs on my phone that were at one point favorites, but are a mystery until they play) kept us company on a 2.4 hour flight. 13 on landing. Winds were 160 at 12 gusting to 20. Wife said "nice landing" which is high praise indeed (on both legs). It's the little things... Love my Mooney. Love GA.

I hear ya. I clearly stated that I am a die-hard LOP (10-15) for entire ownership of my plane. THAT is why I was very surprised at the HUGE boost in ground speed indicated with increase in fuel flow. This was to beat some weather. An hour in an over 700 hour relationship with the engine. No regrets. I don't "need" to get there, nearly ever, where 10-20 minutes matters. It did here and cylinder temps were just over 300 across the board. I agree that I was ROP. I did a quick push and 12.5 came up and so did the speed. The wonky indications on the G3 showing white vs. magenta (ROP) were weird to me. I am a big pull guy when I lean. Lean quickly to rough and enriched/fine tune.

Thanks. Makes sense.

Only increased fuel flow Tommy. No change in RPM.

Nope. Literally gained 20 knots in a minute

I guess my biggest surprise was gaining 20 knots by increasing fuel flow 2.5 gallons

Funny, that is the same article I just read. Check out figure 5 or page 5. That's where I got my above comments. My manual on my Plane from Mooney shows those fuel flow's at 5000 feet. No Redbox back in those days…

I just pulled a MB article on red fin. If below 75% power LOP no problem with red box LOP (my normal is 70% or below). At 85% power could be in fin/box LOP. Maybe I was there on that fuel flow at 5500? Dunno? Cylinder temps were happy. Beating storm and gaining 20 knots was worth it on this occasion....? Me thinks yes.

I do not agree with this. Even at peak not in red box, unless all I have previously red is not accurate. Not a ROP guy so not sure where box is on ROP side. I would love a reference on Peak to LOP being red box. Post it here. All ears and eyes on that.

No. Red box is 50 ROP to 100 ROP, right? LOP is not red box.

I hear yeah Totally agree. My lean find was still indicating LOP on the G3 at that fuel flow. Weird. It changes color on ROP. I changed to the HP screen and it gave about 75% if ROP and was below 70 if LOP....Do not ever do this. Beating a storm. Cylinder temps were 300ish. No regrets, but agree I was ROP at that setting. No clue what was going on there. Maybe was not showing color?

So, flew up north with my wife and two dogs Thursday. No weather in forecast, and then when launching saw Weather painted over Twin Cities. Looked like we were OK, at 7500 feet, but we're only doing about 130 knots. The usual cloud build up around lacrosse caused me to drop down to 5500. I generally run about 9.5 to 10 gallons an hour. This is lean of peak. The weather was closing in so I decided to increase fuel flow. Ran 2500 RPM but increased fuel flow to 12 1/2 gallons per hour. Speed jumped up to 150 knots. The fuel flow/G3 was showing I was still lean of peak. Just, but still lean of peak. It surprised me. I never fly at fuel flow that High. Drop down to 3500 and reduce fuel flow to 11 1/2 still lean of peak indicated? Happy ending as we fueled, tied down, and got back to the cottages as the weather closed In and winds really picked up. Nice to know the old girl can get up and go when needed for an extra gallon an hour.

+1 Fill to six quarts. Same formula for 700+ Hours.

Welcome. Enjoy!

Should of asked about the tail design...

How many hours on your airframe?

To answer your question, nope. nicest E ever is mine. Why? Because I know it. I trust it. Because it delivers friends, family and I to experiences we would otherwise never have. That can be done for a lot less money.

No thanks on that price. My airframe is 2600tt and engine is 700 since major and new prop. Sold half and hope to sell another third. Cheap safe transport to cottages that are also free(God bless my in laws. Picked up my son in Madison Thursday and an hour and a half later watched him take his first Grouse over a point from my two year old Pointer. Value? Priceless. Admission? Attainable.

I've been watching people for over 50 years. Doesn't make me an anthropologist...

Is this helpful in any way? Face palm.
