egt gauge

[selmerguy]

i got my egt gauge today. autometer carbon fiber. anyway it is in the package and the needle rests on about 120 or so. is this right? or should it be on 0

 

[BigRand]

Well I don't remember what mine rested at when I bought it, but I do know that it will rest wherever the temperture of the car was when you turned it off.
So assuming that autometer tested their products before shipping that could be the case.

just making sure here. on the 420a motor i should tap the # 4 cylinder right. looking at the motor from the front of the car it is the one on the right, correct?

Correct.

That's #1, and yes, that's the traditional sensing point for those unafraid to feed molten thermocouples to their turbines.
Others choose to mount after the turbocharger.

sorry i thought you counted starting from the timing belt side to the tranny side like on a v8. in witch case it would be #4 but thats a petty point. i got it done and ended taking off my manni to clean it out.

So your saying that on the 420a motor, the number 1 cylinder is on the far right? (as if you opened the hood and looked at the motor?)

Good advice I mounted mine after the turbo to avoid potential of running metal through the turbo.

No, dammit, my mistake. I forgot about the 420a being reversed. Duh me, my apologies. I'm very old, can you help with this diaper?

 

[DGajre777]

Isn't there a big difference in readings with the probe after the turbo instead of being in the exhaust manifold?

i should get a green square for that one

We for give you.
Don't let it happen again,

I agree with defiant. Mount it in your DP... I wouldn't want it to break and go through my turbine... that would suck. I mounted mine in my DP, about 6 inches from the turbo.

Also, about the needle floating, hook power to it and see what happens. It should go right to 0

Dido on the downpipe again. I would have recomended it earlier but most people are set in there wasy when it comes to getting certain readings.
Just remember to the difference is about 200 degrees F between the manifold and the downpipe after the turbo.


So your max egt's should be 1600 vs 1400 at the manifold. (someone correct me if I'm wrong)
