O-360 #1 cylinder running cold

[MIm20c]

Wondering how I should approach a single cylinder running cold in cruise. Can the baffling be adjusted  slightly or should I not worry about it. It gets really cold in MI over the winter and would like to keep more heat in the cylinder. M20c

100 degrees is a pretty big delta given the EGTs being pretty in line. I would suspect the probe. Swap two and see if it follows the probe or the cylinder.

What is your EGT peaking at 1481?

Mine routinely peaks 1500-1525, going by the little needle. It all depends on where the probe is placed in  the exhaust; move it a half inch, the value will change. That's why everyone says the absolute values don't matter, just distance from peak.

My #1 cylinder can get down to 246 in the winter time.

Trust me, it's a good thing as when the temperatures get up to 85F, it will go up to 320, etc. Enjoy the extra cooling, I was concerned about it, but decided it wasn't a problem and actually a good thing after speaking to a few people.

On cold days, I've seen similar results. I don't think I'd lose any sleep over it.

I understand my question was is that where his is peaking at, nothing more.

Just received the plane so I don't have the data to answer your question. 

The egt's look well balanced for a carb engine. I was just wondering if anything could be changed to help in cruise. These temps were on a nice 60 degree day. I'm not sure what the readings will be when the temps drop 60 degrees.

+1. With a 60 degree day it's not cold enough for that cyl temp to be that low. I too suspect he probe.

What is the 1481 all the way to the right on the JPI indicate?

My number one CHT runs cool too.  The EGT is fine.  Its not the probe because I swapped it with another one.  I don't worry about it.

Aren't you flying a C? With a TURBO?

TIT shouldn't be part of  your 830's display.

Configured correctly you can delete that field and add FIVE MORE fields of your choosing below your existing ones. One of my favorites is MPG!

Mlm,

You really want to include the fact that you have a Turbo to get proper responses to your question.

It is a good piece of info to have placed in your avatar area.

Best regards,
