mounting the egt on a 2g manny

[DSMTurbos]

i was just wondering where everybody has there egt mounted on the manny and if they have any pics of it. i have seen many variations of where it should be and just wondering what everybody here does

#1 runner 4inches from the head.

that is right next to the little lifted section correct? i was thinking of doing it right before it

 

[larryd]

ok thats where but i wanna see how people actually mounted it.. how do you get the probe to stay in the manifold?

Runner 1 likewise about 4 inches from the head

I used a tap & die set to put mine in . It threads right in .

Yep mines mounted right behind the lifted section. I just tapped the mani and screwed it in.

when you drill into the manifold make sure the car is running and you use PLENTY of oil. the oil will keep the bit from seizing and the exhaust gasses will push all the metal shavings out...metal in the turbine is no good! (i believe it is a 1/4" pipe tap)

 

[larryd]

did you actually take the manifold off to tap it? I left the manifold on when I drilled through for the probe but I didnt actually tap mine..

 

[eyebrowski]

you should DEFINATLY tap for the EGT. you will get exhaust leaks in the future if you tries to atach it anyother way. any type of epoxys will not hold up to the high temps of the mani.

If you leave the manifold on then the metal shavings are going to sit in your manifold. when you start the car up they are going to shoot through your turbine housing and could damage your turbine wheel. So it would be better do it off the car and most definatley tap the manifold.

you donthave to take it off...just leave the car running. it might get a little hot so you should wear gloves.

Is there a certain distance from the head that is recommended. I noticed a couple of you said 4 inches. But is it really that critical. I have mine installed about 1 inch from the head because my header is wider near the port, so the EGT probe will be less of a restriction in the tube. I've heard people say that further down the runner is better because there may still be fuel burning in the exhaust manifold a few inches after the port. But I would think we are more concerned about the temperatures in the cylinder than what happens after it leaves the head. Anyone care to share some thoughts?

Thanks for the link, but it did not answer the question of proper location for me. Was the 4 inch location based on convenience or the proper location based on real testing.

I did notice that my EGT responds much faster to temperature changes while driving than it did before when it was further down the runner. I would rather know the temp is too high before molten aluminum is passing by the probe.

When I did mine I left the car running so as to blow the shavings out .
Wear some kind of eye protection because when I was in the act of drilling the initial hole there were lots of shavings flying up in my face & eyes. Not pleasant.....

i am going to have my manifold off to do it anyways, i have had the gauge for 4 month, and just was waiting to pick out a turbo to put in with it off

Read the whole thing , it has links to pics hilighted in the procedure part.

I think everyone is missing the point of my questions. I looked at the pics and read the entire page. But it does not show or state why the distance between 4 & 8 inches is the "correct" place to put it based on factual data.
It just seems to be where everyone puts it because of easy access vs. the best location for flow & response.

I have a Westach probe. It came with instructions that said to mount it 4-8 inches from the head.
