Personally I'd like to see a test similar to the one Richard posted in that other thread with a slight modification.

I'd suggest taking some plugs sized to fit the dump valve outlet and drill holes of various sizes through their end. The goal would be to create an orifice that causes the compressor to cycle on say 15-30 sec after the valve is first opened, with that particular stored volume.
Then record the cycle times over the length of a match.
It would also be interesting to see what happens when the orifice is sized so that the system is unable to build enough pressure to shut off during a normal match length. I know I've seen robots the compressor continues to run for the duration of the match either due to leaks or high demand.
Note if there are no spikes lying around a standard automotive relay could be substituted, just grab Andy's or maybe Danny's keys and borrow one. Just make sure it is for something mission critical like the fuel pump or PCM and not one they can do without like the AC compressor.
