Eliacim, Good reasons for wanting an EGT. I found I had difficulty seeing any peak in rpm. When I got to the running rough stage, it was hard to hear and feel it on my Coupe when it began and I saw little rpm drop till I was way past peak. I flew MUCH more confident in my leaning when I used a high-accuracy EGT. I could find peak easily (if slowly with a Stromberg carb) and easily set 50° rich of peak for normal cruising and 100° rich of peak for max power for high altitude takeoffs. Some guys assure me that they can hear/feel the correct spots but I couldn't. This can be due to my engine (by accident) having a more even fuel/air mixture from cylinder to cylinder. Uneven fuel/air mixtures from cylinder to cylinder cause greater roughness when the engine goes to the lean side of peak. I just had a hard time feeling it. I wanted to fly on the rich side of peak so I used the 50°/100° recommendations I had researched. (Not guaranteed - worth discussion and better research.) I liked my EGT gauge and often flew high on thermally days to get above the thermals. (That's something we can do in Iowa and Illinois that you may not be able to do in Texas, the Southwest or the Intermountain West where thermals go higher than non-oxygen pilots.) And, the EGT gauge, combined with my extreme climb prop gave me enough climb that I could go high over the mountains out west, take off in the first 1/3rd of every runway out there and have a relatively safe western tour.
