I would recommend the 4 probe. You can very easily see a lean condition on a particular cylinder with an EGT, in the same way you see a hotter than normal head with a CHT.
And you will be able to use the stromberg mixture control more effectively (at altitude of course) Bill To: [email protected] From: [email protected] Date: Mon, 28 Jun 2010 12:05:48 -0500 Subject: Re: [ercoupe-tech] CHT and EGT Hi Eliacim, A doctor (or a nurse) physically checks your pulse and then listens to your heart with a stethoscope when evaluating one's health. Similarly, both the CHT and the EGT give different perspective as to one's engine's health while it is operating under load in "real time". You "gain information", but how much use that information is depends on your understanding of our little Continentals. Such information is valuable not only for trouble shooting, but also to operate with efficiency. The proficient pilot can lean more aggressively and effectively by knowing conditions to avoid, and can observe advantages and disadvantages (in terms of rpm and related power) of a particular setting at various cruise altitudes. Since winds aloft can vary considerably with altitude, the "bottom line, here, is always going to be the "best" ground speed (or available range) according to a GPS.

If one cylinder was going bad for some reason, I could see the difference in temperatures and know where to start troubleshooting. Now I plan to install a 4 probe EGT, with the same purpose. The question is, for troubleshooting purposes, am I gaining anything by having a 4 probe EGT, in addition to the 4 probe CHT?
