EGT's are worthless unless you have 1 on each cylinder to compare temps. But if you were to put at least one EGT, it would be best on cylinder #3. The firing order is 1-3-4-2. If you look into that order, cyl. #3 is getting heat soaked by the cylinders firing next to it. Therefore you would want to put your EGT on the hottest cylinder only a couple inches away from the flange.

But like i said on each runner would be best

 

Do what he say #3 usually the best I've seen people on other vehicles put it on #3. the closer to the port the more accrate. On the downpipe isn't the best place. u'll get a reading but it will be off abit.

 

number 3 it is, thanks

 

No, prob

Are you using an AEM EMS ? If so, I would highly recommend using an egt on each runner because there is a parameter that lets you hook up 4 EGT sensors directly to the EMS. You can log the data or set up a fuel trim based on your exhaust temperature.

 

okay, HERE is the picture of the FULL RACE CAR with the EGT welded in... for all thsoe non believers out there.. it's there.. on teh full race webpage..

 

Right on #3
