anything over 550 c steel gets very soft after that ,
mine runs from 100 to 500c change down a gear or back off , the throttle to keep it down

Drill & tap the exhaust manifold and install the EGT thermocouple before the turbo. Or find something that you can unmount from the manifold in order to save metal swarf from getting into the turbo when doing the job.

I installed mine on a metal plate which was blocking the old EGR pipes, and it was right before the turbo. This is on an old school 2.8L Daihatsu donk with iron block & head, but you may be able to find something similar with your engine.

As far as temps go, I'll back off throttle a bit when temps are reaching the 650 degree mark.

It's interesting to see how much the EGT will rise with a slight incline on the open road at 100kph, or with a headwind.

For example, on my way to work, at 100kph, the temp is around 450 degrees. On my way home, it's around 400 just because I'm ever so slightly increasing/decreasing altitude over the 20 km distance.

as above.
pre turbo is best otherwise your guessing at the temp drop caused by the turbo.
make sure the probe tip is in the center of the actual flow, especially if using an egr port. i had 100c difference with a longer tip sensor that got into the flow.
max temps depends a bit on engine. most factory turbo are ok up to 800c. however if your running say black top td42, it has lighter pistons so they tend to have a lower max temp.

cheers guys.. mines a silver top with a AXT garret, I have noticed a bung in the exit pipe from the turbo, what Im hearing is best to be pre turbo correct? as its cooler on the other side?
Kit arived today and quality looks good its one from https://www.autobox.com.au/ and bloody good service to
As far as the boost goes there is a pipe running from the post turbo pipe to manifold that heads to the diesel pump.. I can T into that aye?
