pryometer/egt readings

[known as sarlo]

ok i just installed my egt gauge and i was wondering what reading i should be looking for, i am on 14psi downpipe fwd 1g talon, where should it be at idle, where it shoud be when i am gettin on it? thanks for reading...

That really all depends on your setup. idle shoud see anywhere from 950F-1100F cruise should be 1350-1500 and WOT should not exceed 1650F at which point shit starts melting.

One thing to note temp ranges should not be used to determine tune. Running too rich and to lean will cause the same affect. The EGT is more of a safty gauge then anything.

thanks for the advice, i know it is not for tuning i was just wondering what the avrage readings were and you answered my qustion thanks ...

Whoah relax there.

Never take somebody elses recommendations for your car because every probe is different. Thats like asking what the best looking hair cut or something.

Where is your probe located first? In the manifold or in the downpipe? How far is it away from the head and what Guage and probe do you have? Autometer has two different EGT gauges so keep that in mind when answering.

The readings that come up all depend on your setup and how your car runs. Based on your tuning you should see EGT in a specific area. That is YOUR safe area. Make sure YOUR car stayes in YOUR area not somebody elses. EGT is a very car specific thing. There are some generalities like posted above however if your probe is in your downpipe and you see 1600deg thinking thats ok, your screwed because 1600 in the manifold is a lot different than 1600 in the downpipe.

It doens't matter where it's located, it's just that it's the same when your using it. Hell you can put the probe in your exhaust tip as long as the temp doesn't change outside your normal reading zone its fine.

True what jims says, just assumed you had it located 6" off the #1 exhuast runner like most people do. I guess I should have been more specific. You will see changes in your temp. ranges when you make mods to your car.

I made the mistake of getting Autometer's EGT gauge instead of the pyrometer. Mine reads in Fahrenheit and only up to 1600. Even though the game is over if you peg the meter, I think I would rather have something to go beyond it so my eyes might catch the movement of the needle rather then it sitting still. However, mine has never gotten over 1450 and that was at extended cruising above 90mph. My probe is in my DP, so I'm not sure how much colder it is at that point.

Just for reference my 1g runs about 1000-1100 at idle, 1300-1450 at cruise (1450 is about 75mph constant cruise) and wot its at about 1500 (i'm running a tad rich right now for safety sake). My probe is literally 2" from the head in the #1 cylinder runner.

I get the same exact temps ...except for WOT i run about 1550

I run in the down pipe as well on purpose, however I have no O2 sensor like a typical DSM setup so my probe is 2" behind my turbo. The difference is about 150deg or so. It doens't matter what the number is just that it's constant.

Your better off farther down so you have more range on the guage vs. right off the head where at normal operation it's at the very end of the gauge. Most gauges are not accurate at the very beginning or very end of the reading spectrum...

thanks for the advice mine is located about 2in from the head in the mani. and i am running 14psi and evo 3 mani. and 3in open down pipe till the q tec is hooked up.... everythings seems to be nomal except the exaust leak i am getting from the man. cuz of studs breaking.....anyone have and good advice of how to get the stud out they are broken inside the head itself.... i know i can drill and use an easy out but that dosent always work and if i should just drill them out what size drill bit should i use and what tap should i use to tap it......
