i was wondering if when you buy an egt gauge it comes with the sensor. if it doesnt where would one find such an item?

Greedy's comes with a heated o2 sensor...

 

The Defi unit comes with a sensor probe and fittings, but you will have to have your DP modded to hold the bung. The rule of thumb is to put the EGT sensor at half the diameter of your exhaust (=radius) from the mounting flange. So if you have a 3" DP, mount the probe 1-1/2" from the flange, and try not to mount it straight up from the bottom, so crud won't collect on the threads of the probe, etc.

cool thanks. . . when you say the defi gauge do you mean all the defi gauges? im planning on getting the d-series gauges. thanks, again.

you dont want to put the egt probe in the DP, You should place it in the manifold before the turbine otherwise it will not tell you what you want.
If your runnin NON-SEQ you can put it like this.

 

while we are on the topic of EGT can someone explain what that thing is supposed to be reading?

Thanks

 

Exhaust Gas Temperatures?

 

^^^^ Yes, the egt gas temps...what are normal values?

good question!!!!! does anybody know how hard it would be to put a whole into the hks exhaust manifold?

paul

 

It around 1400-1500 deg F. Mine is running between 1200-1300, which indicates I am running rich. Check ot the following:

why does a EGT gage come with a heated 02 senser from Greedy?

 

haha, i was just gonna let that one go.

 

Thats sweet... next time I have my turbos off I will have to do that.

 

One thing to consider if you mount it in the exhaust manifold and a part of the tip comes off (which does happen with our very hot exhaust temps) it will destroy a turbo.

If you mount it just past the flange in the dp you dont have to worry about that. I would just stay more conservative with my readings knowing that its really a little hotter than what its showing.

Also, just because your reading is more or less hot doesnt necessarily mean your rich or lean. Timing plays a huge roll in exhaust temps.
