Is it okay to use DP bung for Defi EGT?

As stated in the title- Is it okay to use DP bung for defi EGT? Thanks

You won't get an accurate reading from there. Tap the sensor into the #4 runner of the manifold.

That's what I've come up with as well. Any idea on what kind of difference in reading one would get?

They will read quite differently, you want your numbers to read correctly if you're trying to monitor the health of your engine. If you're going to install an egt gauge i suggest installing it correctly or having someone do it for you http://www.scoobymods.com/mod_egt_pr...ht=egt+install

Yes, I agree, that's the whole point of having gauges. I was just curious and wanted to know what the difference in temps would be- higher or lower?. Can anyone here confirm that 850-950c are safe numbers?

Safe numbers for what? Having your egt gauge in the d/p? The temps will be lower for sure the further away from the cylinders you are. Yes, you could technically run your egt gauge in your d/p, but that's only if you knew what your actually egt readings were that are coming out of your block and then compare them to the d/p temps. But we can't tell you the exact egt temps that are coming out of your block. If you have an egt bung in a cat-less up-pipe i'd go with that before the d/p.The closer to the cylinders the better.

Safe numbers for having the sensor tapped at the manifold or the up pipe.

The magic number is typically 1550-1650f. Although the egt's can vary from a tune with different amounts of fuel/timing.

my car normally runs between 700 and 850 celsius depending on driving conditions
