Went to help a friend move a grill this week. He is an engineer. In his work bag sat an infrared digital thermometer. Just aim, shoot, and sweep.

My turbo oil line sit about 1/4" inch under the hood, the housing itself sat about an inch below the hood. I measured the temp 3-4 minutes after running at highway speeds.

The "hotspot" on the hood was where the turbo lies underneath, no surprise. The max temperature was 143 F. I popped the hood and shot the turbo, housing was 530ish and exhaust was 430ish. I bet the sun makes to hood hotter on a hot day!

Not sure how applicable it is to everyone...... but it is real world verified to +/- 1 degree F under said conditions.

Depending on your vehicle that might be useful to see where you need more insulation or shields to insulate interior panels.
