i just intalled my egt gauge, but i dont know what it should be reading at idle, or when i am near redline, etc? Does any one know the degree variation?

yes, im curious too. Mine usually sticks around 600C driving normally, and around 700-750C near redline. I hope thats not bad

It really depends on your install location. Even a few inches can make reading vary from car to car.

where did you place yours? If you placed it close to the o2 sensor it should read about 750 at full throttle if it's tuned right.

Mine is placed about 5 inches away from the O2 sensor, its located on the downpipe.

i put mine about 2 inches from where the down pipe starts, but at idle it stays at 800 and when i am at about 3500 rpm it is at 1200 wtf is going on?

You are running lean, thats whats going on. What mods do you have? at idle it should be at like 300 or 350

I wonder if everyone is talking the same units?

You are fine.......if we are talking 800F-1200F

When you guys are discussing temps that are important like this you REALLY NEED to specify C or F. Your egt's are fine, if they start getting much over 1400F let us know.

In addition this is an egt gauge not a wideband. If its reading hot that doesnt always mean your lean. This is why you need to tune with a wideband and just double check it with a egt. You need to tune a/f with the wideband then when its in a safe zone they use the egt for thier timing.

Yep, most of the guys at the track see their EGT's pegged after some laps.

I have my sensor about 6-8 inches away from the manifold and usually see between 1200-1400F

EGT's are supposed to be ~700-~720 celcius at WOT. The temps actually drop a little @ WOT, so cruising in 5th gear they may approach 700.

I have my warning light @ 740 and have not hit it yet. Not sure on the sensor location. Steve Kan did the install and the tuning.

And your post once again brings us to another problem ... location. Let me guess your EGT is in the downpipe? You can't say 700-750C without saying where! Mine is in the manifold and I see 950C all the time.

poo. . . i was planning on putting mine in the downpipe. . . where the o2 sensor was. . . should i not?

There was a huge debate about EGT sensor locations in the Rotary Performance section about a year or two ago. Basically, there is no "one" best spot. The problem is when comparing EGT values to other cars that the sensor location really matters.

rotorbrain

so, i should go with a location that the closest tuner is comfortable with. . .

That would be my suggestion.

i have an autometer egt, and i placed it about 2 inches from where the down pipe meets the turbo manifold (near the O2 sensor) that is what autometer suggested. So if i am at 800 to 1000 degrees fahrenheit at idle (depending how hard i am running it) i am ok? And if i get to red line and I see 1400 or higher then i should worry? Also my mods are a cat back and down pipe.

I think it would be ideal to do this mod to a car that's running well. That way you can check your ideal temperatures for idle and redline, etc. and then compare in the future if there seems to be a problem with your temperatures.

the car seems to be running well, it boosts fine and no hesitation ever, just has a funny start up every now and then but once warmed up it is all good.
