My gripe is with Walter, not GAMI.

Walter is a dentist, and clearly not an engineer. His association with GAMI
was never that of an engineer. He should leave the engineering to George
Braly and the talking to John Deakin.

You also totally missed the point. GAMIjectors are great. They do everything
as advertised. But most of what they do is an answer to a problem that
doesn't exist. I've used them since GAMI serial #19. Engines ran great
before GAMIs however. Twenty years ago Continentals ran easily to TBO. That
is not the case today and a set of GAMIs will not help the longevity of
these poorly built engines at all. Even John Deakin burned out a set of
Continental cylinders in 500 hours LOP in his Bonanza. And their highly
touted fuel savings are, for the most part, due to a decrease in speed. You
know, all that drag increase with V squared.

What is your agenda? You seem to have an axe to grind, and you get your
facts wrong.

For a given power setting, in general (module altitude effects), there
are two mixture settings to give that power. One ROP, the other LOP.
If you run at, say, 70% power, your airspeed is going to be fixed at
a particular level, assuming stable, level flight. If you run LOP,
you run less fuel through the engine, and you burn all of it up. If
you turn ROP, you use some of it to cool the engine -- using more
fuel than LOP operation. All this for the same speed.


CHTs are just fine ROP.

What CHT level do you think is "just fine"? How does this argue
in favor of ROP?

Engines run clean enough ROP.

On what do you base this unsupported assertion?

Engine stresses have been doing just fine now for 100 years ROP.

Oh? Have you ever examined the operations of round engines,
especially the bigger things like R-3350s? IIRC, LOP operations
were mandatory to get satisfactory performance and engine life.

CO is not a problem in maintained exhaust systems.

What does that have to do with the decision? LOP makes less CO;
isn't that a positive?

Airplanes fly faster ROP.

That claim is especially brown and smelly, given the orifice it
was pulled from. See discussion above. Speed is all about power
levels.

Even the LOP diehards admit engines run smoother ROP.

As opposed to the ROP blowhards who can't abide admitting they might
be wrong? See! I can use cheap rhetorical devices, too! Would you
care to try a logical approach, or are you just interested in being
fanatical?

Gamis have more value in a turbocharged engine.

What does this have to do with deciding to operate LOP? Or are you
just trying to obfuscate with more irrelevancies?

And, I have plenty of dirt under my nails, thank you for asking.

Do you have real qualifications to back up your amazing assertions?
How about real data? Sound logical reasoning?

yours,
Michael
