Pre turbo pyrometer a really bad idea?

Hi Guys,

I installed the sensor for my pyrometer in the exhaust manifold, just upstream from the turbo.

Today I had a conversation with a guy who runs a turbo repair shop. He said that is a bad idea, because if the sensor burns off it will go thru the turbo and wreck it. He recommends mounting it downstream so it is cooler and is less likely to burn off, plus if it does it will just rattle out the exhaust pipe. As far as readings, he said just deduct 300 degrees for a downstream temp. Seems to make sense to me, I am considering moving it.

What do you guys think? Has anyone ever had one mounted pre-turbo burn off?

Thanks, Joel
