Old pyrometer, a day in the past?

I have a friend who as an old pyrometer that he used to run with his powerstroke. It is a big gauge (about 3" wide 2" in height and 3/4" thick) When he had it installed he just hose clamped the thermal couples onto the outside of the manifold and put some insulation around it so the wind and outside temp didn't affect his reading.

It makes sense that it would read the correct temperature with the heat being transfered through the manifold to the thermal couples. But it seems like the gauge would be very slow to react to the heat exchange.

I have not read anything on this because I could not come up with any search results about it.

What are your thoughts?

Inaccurate as hell. The manifold is not going to heat up as fast, or to the same temperature as the gasses inside it.
