I believe you want to put it in the hottest area to find out which cylinder is leaning out first so you can correct it. Ive heard put it in the number 4 runner because its closest to the tranny and seems to run hotter. the idea is to get a temp idea to see how well your a/f is. the hotter it is the leaner you are. fuel cools the combustions chamber. I believe im right about it but anyone elses opinoins would be much appreciated

I believe the purpose of an EGT guage is so you don't burn up your turbo; like boosting for a long time while going up hills and such. At least that's what the guys with diseal trucks use them for.

i understand that its good to gather the hottest temperature.. but woudln't i still get an idea?.. instead of 900c it would show 600c and if 700c then 500c.. etc.

so how efficient will this be?

i guess that's the hottest cylinder</TD></TR></TABLE>
yeah it seems from my own comression test and numerous others the number 3 cylinder is almost always the weakest. so i guess 3 would be ideal to monitor the weakest link so to speak. i think some one was saying since 1 and 4 are on the ends they are sealed better and have more water collant flow over them. 3 and 2 run hotter and 3 was the worst out of the 2 for some reasons i can't think of right now.

yes.. #3 seems to fail the most.. including mine..
now.. what about running of the elbow.. drilling manifold isn't an option.

If you run really rich the EGTs can go up as well. I just finished an RX7 turbo II engine swap. The O2 sensor wire had broken inside the harness and the car ran really rich at first. Just idling with a little reving the turbo got orange, fast....
The tranny doesn't have anything to do with the EGTs. EGTs are more affected by fuel & air distribution to the individual cylinders.

Re: EGT gauge in wastegate elbow? (mamaboy)
well.. thats my other option.. i just thought it would be more accurate before the turbo.. since i have wastegate elbow.. its not that far above manifold.. i think i'll give it a try.

i had just heard number 4 because of the retention of heat caused by the tranny just something to think about, I know its a measure of air fuel the hotter it is generally the leaner you are running, and yes 3 seems to be the weakest it was on my b16 also. idk if tranny could cause it to retain more heat but thats just what i heard. I will also be putting it in number 3

Re: (mattb16a1civic)
2 and 3 suck because of coolant flow, 3 is worse because of the engine firing order, it fires, then the two around it, as well as being next to last in coolant. anyway, you need to tap on #3, and distance from the head should be half the diameter of your runner.

^^^^weerrrddd. i think t would also be helpful if someone could find a way to easly put the egt on each cylinder to measure differences, this way you could identify rich cylinders, faulty injectors, valve clearances, etc.
