I have a weekend turbo car, it's a basic piston/rod ramhorn, 60-1 build. What I am unsure about is what is a "normal" egt range for cruising speeds. The probe is a couple inches off the head flange on the #3 runner. I seem to cruise @ 1200ish @ anything under 55mph, but 55 and above it cruises between 12-1300 and interstate speed is about 1350 maybe 1400 max. I usually don't allow the car to go above 1300 cruising. I am just looking for some clarification. I don't want to cause any premature wear on anything that can be prevented. Btw, I have noticed my temp gauge is rock solid and does not run hot according to it at any speed. Thanks.

 

Have u read the FAQ section talking about it? I know it goes over the temp differances.

 

No, i will check that out though.
