on a 4.2 turbo where is the best place to put the probe for the pyrometer, before the turbo, and if so where? Or in the threaded fitting in the dump pipe.

Best before the turbo as there is a huge heat loss through the turbo
which will give a lower reading and give you a bum steer at the gauge

thanks for reply. I read somewhere that the max temp on the dump pipe side is 200c below other side. this would be about 530c then.
