The results are preliminary, but interesting never the less. The filter vacuum reading is inconclusive since the gauge pegged out at 2 inches of water. Incidentally, the air compressor is getting its air from the canister as well, but there was no indication on the gauge when it was loaded (sucking air).
The ambient was about 62F. Deuce as shown below.
The air temperature must be different for the individual cylinders since the paths from the intake manifold adapter vary in length. Number 3 cylinder must be getting hotter air than number 6 for example.

I drilled the holes knowing that some debris would fall on the inside of the manifold, but it's all aluminum and a test drilling on a spare manifold resulted in very little debris. The thermocouple probes are 1/16 inch dia and fit snuggly in the holes.
