Just as a data point, I did exactly that (90, heat soaked, climb to 9).
I did have one cylinder hit 400 but the rest stayed under 380 as they
always do. Having problems with cylinder 1 which breaks 380 regularly
climbing out during our southern summers.
But this is a stock '10 with a stock IO-540 pulling 2600rpms with a
stock 2 bladed prop. I normally climb at 135 and start dialing back the
speed to 125 by 9k.

Kelly,
The ground temp was just north of 90 degrees. The difference may be that I
have a plenum instead of the baffle seals. Once I reach 1000' I pull back
the power to around 25" & 2500 rpm and lean to keep the same get as
takeoff.

OK, that explains a lot. Did you fabricate the plenum or purchase it? If
purchased, which vendor? I only have the stock baffle seals.

The other thread talking about cowl flaps got me rethinking another kind of
cooling issue that I am having. I can't get my oil temps to climb above
140. It doesn't matter how hot it is outside or how long I climb, they top
out right at 140. Could this be caused by me having a plenum and having too
much air flow through the oil cooler? The probe registers ambient
temperature correctly when not running, so it seems to be accurate in that
regard. Can a faulty vernatherm cause this?
Any ideas?
Thanks,
Shannon

Run it into a pot of boiling water and see what it reads. First thing is to verify
the probe is working correctly.

In non-summer conditions I had the same problem - just couldn't get the
oil temp up to the minimum.
It seems that the combination of running less oil (6-7 quarts) and
blocking some of the airflow to the cooler with a plate installed in the
engine shroud fixed it. I don't recall ever changing the oil temp probe.
No change is required for NC/FL summers but I do reduce the size of the
blocking if I remember and run another quart of oil in summer.

I added another opening on each side to improve oil cooling. I also have
an additional oil cooler. Seems to be good enough now for Yuma's hot,
hot weather.

| Subject: | Wet Dog Syndrome On Shutdown |
My first IO-540, so not sure if some of this is "normal", but the darn
thing shakes like a wet dog on shutdown.
I've modified my shutdown to use a higher RPM when pulling the mixture.
That helps a little, but still very noticeable.
I'm wondering if there's more to it and I need to check a few things.
Maybe need another washer on the isolator through bolts to tighten them
up a bit? Do I need the stiffer isolators? Maybe I need to re-check my
engine mount bolts, but I'd think that would be REALLY noticeable if
they were not to spec.
I did have to add a washer to the nose gear isolators to snug those up a
bit about 10 hours ago and I had custom VA-143 and VA-144 made to
correct size. That helped a little also, but I'm still
seeing/hearing/feeling a good deal of shake rattle and roll on shutdown.
Any other tips or guidance on things to check?

Sean,
Are referring to excessive(?) physical shaking/vibration of the engine @
shutdown, or are you more concerned about the engine not shutting down
promptly and 'running on'?

Hey Deems!
Yes, what I feel to be excessive shaking of the engine at shutdown. It
does not run on.
Been following the Lyc recommended shutdown at 1200 rpm then ICO.
Shaking like crazy with that procedure. I've read other shutdown
suggestions on the interwebs, but can't find anything that works, which
leads me to believe it's some kind of isolator issue or something.

Try shutting it down by killing the mags and see if it is smoother. If you are
cutting the fuel off completely, it should be as smooth as killing the mags. They
all shake, but I've never thought of it as excessive.

I assume what that would tell me is if I have the mixture properly set
on the servo to REALLY be at idle cutoff?

It's my understanding that most fuel injection systems have a spring-loaded
valve at the distribution manifold to allow for clean, quick shutdowns once
the fuel pressure drops below a certain threshold. Seems like if this were
failing to close cleanly some of the cylinders might run longer than
others, thus causing a shudder... Shutting down the ignition would
eliminate that as a cause.

or the mixture cable isn't extending enough to fully close the fuel flow.it
does sound like the aircraft is at a 400rpm mode and struggling to stay ru
nning with minimal fuel flow.

Pull the throttle back to idle. Should be at or less than 1000 rpm. Then go
to ICO. Should shutdown quickly and smoothly, assuming it idles smoothly.

Your mixture should give a 50 rpm rise if you pull mixture slowly to
cutoff. If more, too rich. If less, too lean.
Shouldn't make any difference where it is set, you should still get
cutoff when mixture is pulled to the stop.

Sorry, but I am confused.
The engine does stop, obviously, just not without doin' the shake. Are
you saying it may be set too rich, causing it to still fire during shutdown?
