I was refering to that left coast.
Joe: Coast, what coast? I live up in the hills with the rest of the red necks. I have to drive three hours west to see salt water. You better get that muffler fixed, the fumes are getting to you. Hope to see you at the next POG rally. Remember too much work can kill ya. "You gotta chill out baby" Now thats left coast talk.
Best to you.

Now, now boys, calm down
As for JPJ's post of the suspended coach. Was that one of your Air Mail inventions?
Hello All,
Well, first off, as for Joe Cannarozzi saying he has a mechanical injected 8V92 and always gets 5 1/2 mpg, well, that is just absurd. Drive up a grade real fast and your milage will surely be lower than when you drive back down. If you are saying you always average 5.5, well, that just means your driving habits are consistent.
And if your air filter is clean and new or old and dirty, the difference in mileage can only be an infiniteessimal amount in any case, even if you are mechanically injected. The injectors still meter fuel in based on the amount of air going into the cylinders, same as an old mechanical carburetor or mechanical fuel injection on a car, or fuel injection on an airplane engine; all of which has been around since the 1950's. Your foot pedal controls an air valve, which allows the fuel metering system to correlate the fuel injected to match. If the filter is dirty, it takes a little more work to get the air through it, but that is such a tiny amount of energy compared to moving a bus along the road it really makes no differnece in mileage. But like I said before, it could affect the maximum horsepower the engine can make if it was really dirty. I hope this makes sense.
Now, secondly, as for BrianE's post about me, to answer Jon Wehrenberg's question, yes, as a matter of fact I do annual Brian's plane for free. And I think his little explanation about me was way less puffy that he promised. Since you fly a P210, you must already be puffed up to a pretty high pressure, better not let any go in my direction.
Now, it seems only fair that I illuminate you all a little about Brian.
1. Brian is a very smart machinist, airline pilot and retiree. Airline pilots always think they are in complete charge of everything and like wearing hats with scrambled eggs on them.
2. For you aviators, he is an A&P, and one hell of a pilot besides, but since he has to buy his own gas now, he never flies anything fast.
3. He approaches all problems from some strange standpoint I have never understood; including social, political and religeous issues.
4. He almost always thinks he is right.
5. His wife is smarter than he is.
6. He has a special talent when it comes to spreading black water tank contents everywhere but the sewer pipe, and he has special shoulder high rubber gloves to wear when that operation is in progress.
7. He often invites us over for dinner, but we never accept since he insists on serving the food on his hangar or bus garage floor sans plates. Now, there is nothing wrong with that since the floor is always spotless, but gee, we have to draw the line somewhere!
I hope this helps you understand a little better.

All I can say is that it's refreshing to have some new blood spread (smeared) around POG. Some new guys to watch harass each other. The old Jon vs Mango vs JW vs Fast Roger was running out of material - kinda like jumpin' the shark.
Go at it boys.
Mango M
Mango: In the resturant bizness, isn't that term "new meat", or does that term come from WWWF? At any rate, I am glad to see Jon is got some competition coming for the 07 "Anal Award".
We may have to branch out into "Bus and Non Bus" Categories.:D
Competition Hell!!!!!!!
I'm going to chase Peter down and personally force him to take it. He already deserves it.
Also, I am going to stay on the good side of Brian and Peter because I may have some help from them in dealing with guys who fly forked tail doctor killers.
It is clear there are also more Kevin type tales, and the Mango Bent Metal award may have to be supplemented with some other award, such as the famous "s**t creek" paddle.
Petervs, welcome to the club! Absurd, I like that caricterization, Ive deffinatly been called worse. We are going to Tenn. for thanksgiving and inbetween Chi. and Indy I-65 it is flat as can be with a cross wind that will affect you the same going both north or south and at 150 miles its long enough for a fuel test. We will go down at 62 and come back at 72 and post the results. All our milage posts are estimates, Mabye you are correct, we might save some, but I suspect it wont be much.:)
Hi Joe,
Hey, I did not call YOU absurd, I just labeled your comment absurd.....
I do look forward to seeing the results of your mileage test. Just be sure the wind is really from the side. If it is a quartering headwind or tailwind that would make some difference. A calm day is best, or at least, note the conditions by standing outside to really check to see how much wind there is and from which direction.
Also, traffic has to allow you to cruise steadily along, preferable with the cruise control on for most of the distance. With my tests, I left the fuel station, accelerated once to the speed I chose, and let the cruise control do the rest.
Let us know what you learn,

Peter,
Question: I think your post about factors affecting mileage was relative to a DDEC (later generation) coach. Would that be correct? If I am not mistaken pre DDEC and DDEC I coaches deliver fuel based solely on throttle position, and thus the driver and the air cleaner condition may have a greater impact on mileage.
I think later generation DDEC models delivered fuel based on turbo boost in response to a CA "snap accelerator" emissions requirement to eliminate sooting on rapid accelerator application.
A-1
Hi Jon,
I am not an expert on pre DDEC or DDEC 1 systems, but I can not imagine that the fuel supply is controlled directly by the throttle position. The engine would flood out if you opened the throttle too quickly, the metering control has to sense the air pressure in the cylinder or going into the cylinder and respond to that.
Perhaps someone else will have a definative answer.
Peter VS
Peter,
On mechanical engines (pre DDEC) the throttle position determined how much fuel the injectors supplied. A wide open throttle at low boost (low RPM) resulted in unburned or incompletely burned fuel (black smoke).
On DDEC I the same condition could temporarily be created. The computer was not as sophisticated as on later versions, and until the turbo spooled up you could roll out the black smoke with excessive throttle.
Our later versions will only allow fuel quantities that can be almost completely burned.
All the above ignores the PBF factor, which can be deliterious as to fuel economy.
JPJ, Don't you have some mail to sort?
I know I saw a post just yesterday about the difference between the ULSD and our older diesel fuels, but can't find it.
So I am posting this website on this post site, HOPE you don't mind.:confused:

Doesn't the "potentiometer" come in there somewhere?

Lew, The elaboration of your query.
Automotive jargon: Throttle position switch. = Electronics jargon: potentiometer.
Personally I think you new that! ;)

In the older mechanically governed 8V92's there was actually a piston that pushed oil out of a tube with a small hole it it that acted as a buffer between mashing your foot in the throttle and the fuel system going to full fuel. If you wanted to improve your pull from the stop sign, just drill the hole bigger, but be ready to face the fact that the sun was going to be blocked out by the black smoke.
The Cummins PT fuel system used an aneroid valve that sensed turbo boost pressure and adjusted the fuel flow accordingly. Mack "Maxidyne" engines had a similar feature on their high pressure injection pump.
I think this is all for naught in the new engines as the sensors and computers keep this all in check with electrons and or 1's and 0's.
