| Subject: | Re: Cylinder Head Temps |
Thank you for all of the great information- especially the discussion on the differences
between EI and JPI probes. One bit of information I left out- the mags
were timed exactly to 25 degrees BTDC (dial indicator/ laser sight etc...)
Thanks again,
Curt

Lots has been said about this CHT measurement system or that but what about sensor
location?
My experience (1977 Tiger) has been that the spark plug location reads significantly
higher than the cylinder head location (probe). About 30-40 F difference.

What should the cylinder head temperatures indicate on a later model AG5B with
good seals/ baffles? Everything I have read says to keep the CHTs below 400 degrees,
but I am not having much success. #4 is running 420- 430 in the climb
with #3 not far behind- I am using a brand new JPI EDM-700 for monitoring. Im
climbing full throttle and full rich mixture at 100kts+ airspeed. Even in cruise,
the temps dont decrease significantly is this normal for a Tiger?

We got back from the Dayton AYA Convention about noon on Friday.
A couple of things upon which to comment.
First, I didn't think I would be coming to (going to) the AYA convention this
year. I hadn't planned for it. I bought a house last year and I'm still
recovering from the down payment and remodeling. SOOOO, I didn't read the Star
articles regarding the venue in Dayton. I mean, why should I? I've been going
to conventions off and on since 1990. They are all pretty much the same. They
start on a Monday, banquet dinner on Thursday, fly home on Friday.
Clytie, my better half, had never been to a convention. I tried explaining what
it was like. No luck. You had to be there. Then, one night after the Red
Bluff Fly-in, while sitting by the waterfall in the living room and watching TV,
my better half said, "Let's go to Dayton." She wanted to fly 28747 to Dayton.
She's quite the adventurer. She loves flying too. We started doing the math.
I don't owe Garner that much! She said, "Let's go commercial." The blasphemy.
"OK." Within the next 30 minutes, she on her iMac and me on mine we searched
for good deals. We finally found round trip tickets for under $800 for both of
us. I filled out the application for the convention, made out a check to Karen
and Stew who had dinner on me (just kidding), and began planning for the event.
A few days later, talking to Roscoe, I learned the "experts forum" was on
Friday. "Doesn't the convention end on Thursday and everyone flies home on
Friday?" Not this year. When I got my 'information' package from the 'home
office,' I opened and started reading. Blah, blah, blah. WAY too much
gibberish and nonsense and not enough real content and information. If one
keeps the previous years' package, you'll recognize it.
Case in point: The colored chart with the schedule of events. 3 point font?
are you kidding? What was the point in the colors? There was no color code to
say what was what. Or was it colored to make it look important? I couldn't
tell. And, the "Seminar" schedule. Seminar? Where on the colored sheet did it
say what the seminar was? Short of going to the room where the seminars were
held, it wasn't obvious to me. But, it was done in Excel.
The schedule: There are times when I just wish people would quit using Excel to
do data bases and text outlines. Excel is for spread sheets. Doing anything
more with it tells me you need to get out more. Oh, I know, you got Excel as
free software when you bought your first PC in 1984 and, by damn, it'll do
everything you'll ever need. The schedule, neatly boxed in with every line
having its own border, had the same information as the colored page but in
slightly more depth. Why not spend a little extra time and a word processor to
make something that looks like a schedule?
Transportation: There was no transportation to and from the Dayton
international airport. I guess if you don't fly your own plane in you're not
worthy. A big thanks to Hal and Vickie Beauchesne (Bow-Chez-Nee) who made two
round trips to pick us up on Sunday. And, an even bigger thanks to Garner for
getting up at 4am and taking us to the airport Friday morning. Then there was
the shuttle, to and from the little airport, hosted by my buddy Mark Matthews.
Clytie and I bummed a ride to a fish restaurant (seriously, does everything in
the midwest NEED to be fried in butter?) with Mark and Kelly. Both were very
gracious and friendly. Clytie sat next to Kelly and a casual observer would
have thought they had known each other for years. Mark, I take back everything
I've said.
The Air Force Museum: No where, anywhere I looked anyway, was there ANY
information on the experimental planes at the Museum. On Wednesday, we got
there early so we could have time to look at the planes. The first thing I
asked the person at the information desk was, "Where are the experimental
planes?" Pointing to her right, "Out that door and that way." Asking another
face in the museum, "Just keep going to the end. They are past the B-2." Well.
Not exactly. The X-planes are on the other side of the base and you need to be
military or go on 'the short bus' to get there. How do I know? We went back on
Thursday (we stole a car and used the GPS in my iPhone to find the museum). We
got there 10 minutes after the LAST bus to the X-planes left. But, "it was full
anyway. So, you still wouldn't have been able to go." says the new guy in the
information desk. Seems to me, someone putting on a show in Dayton for pilots
would have spent more time arranging these excursions. The museum could have
spent more time with signs explaining the lock-down on X-planes.
New and old friends: Wow, where to start? Garner, Mini, and the kids. They
are like family. I've known them longer than any of my marriages; in fact,
longer than all of them combined! It was Celise's birthday on Thursday. That
was fun. It was great seeing Ian, we talked about taxes, and Nigel, now I know
why he's called Grumpy. Charlie and Carol Adams. Gil and Doris. Claude
Allen, Patrick/Theresa, . . . . Wow, looking over the list of attendees, I
count no fewer than 45 people who we saw and talked to who I already knew. We
also made several new friends. John Betsill who spent 30 minutes chewing me out
for saying the YF-23 was better than the YF-22 (he overheard me saying that to
Dave Fletcher). Turns out he was an engineer on the YF-22. Oddly enough, since
I worked with a good many of the folks who went on to test fly and develop the
F-22, we knew many of the same folks. John, I still think the YF-23 was better.
Bob Hodo and I carried on like we've known each other for years. And, of
course, my new friend Mick Beede, who gave us a ride to the Air Force Museum in
exchange for a 60 minute dissertation on what to do and not to do if he wants to
replace his own windshield.
The most interesting experience was observing behaviors. I guess I had noticed
before, but it never totally sunk in. Ron Levy, walking toward me, did an
abrupt "eyes right" about 10 feet before passing in an effort to avoid eye
contact I guess. Very child like. Others would intentionally start a
conversation and, when asked a question, would say, "Hold that thought. I'll
tell you later." and then disappear. I guess their thought is, "knowledge is
power," and now they know something I don't. I wasn't impressed. Some AYAers
were down right rude. Again, Mark and Kelly were the most impressive in what
could have been an uncomfortable situation based on past history.
Time to go to work.
Oh, yea, Bill and Carol Scott. I got to watch them as they annualed a plane in
a hangar at the airport. I must say, they did an very thorough and complete
annual on that plane. On a new plane, new to me, I usually break down the depth
of the annual over the first couple annuals. I cover the most critical stuff
first and the not so critical stuff later. For example, the glareshield doesn't
come off. I crawl under the panel and check for interference with cables, wires
etc. I even oil the chains from below. Now I know why they charge $2500 for an
annual.
Take Care

I like the JPI. The leads are easier to route. You can trim to fit
them so there isn't a lot of excess wire all over. The probes are
generally faster response. "I" think the gauge is easier to read and
interpret, but, I think that may have to do with not having much time
behind the EI. The connectors behind the unit are smaller and easier to
work with. I've heard over and over how the EI is cheaper. It's
subjective. Side-by-side, feature-to-feature, the JPI has more of the
features I want already included for the same price.
Cliff, has has a lot of good luck with EI. Maybe he can tell us why
he prefers it.

| Subject: | Re: Cylinder Head Temps |
Bummed out about not making the convention:(
Been able to do some work on the Tiger - Jaguar.
Experimented with the right front baffle and have the CHT's all reading
the same (within 1 degree) at lower altitudes. Thats at best power
level flight at 4500DA with OAT 86 deg F. All read around 354degF. On
climbout was seeing a spread on CHTs 380 to 400 with OAT at 100degF at
about 90kts 1250fpm. All this with no air exit at nose strut....
One oddity I'm not used to seing is that at some richer settings the
CHT's are higher and more uneven than when leaned out. Any ideas?
Still working on the speed.
Reinstalled the old cowl in order to center the engine. No small feat;)
Engine was still down about 3/4" and to the right about 1". Just like it
was before the Jaguar cowling install
Found the upper left shock mount bolt had NO threads showing thru the
nut....Tightened to spec'ed torque and checked other 3. This brought the
engine into center of old cowl
Next project is to center Jag cowl raising it about 3/4" and moving to
left about 1"
It now flies straight and level hands free with neutral trim tabs and
equal flaps whereas before it tended to turn to the right.
Allo for now,
Your Fellow Grumman Enthusiast,
Ned
