Calibrate Pressure Switch?

Take a look at the rated outputs of compressors the lower the pressure it is working against the higher the cfm. Or take a look at your gauge when you fill the system from empty you'll find the rate of increase in stored pressure decreases dramatically as the stored pressure rises.

This discussion got started because the OPs switch was turning off at 105 psi. I am not sure where the point of diminishing returns on your system is, but I would say generally speaking I expect it is more than 105 psi. Our comp bot was good at 110 psi. I think our compressor was on for most of the match so the HP cutoff wasn't that important. If you are running a off robot compressor, there is a big difference between 105 & 120 psi in terms of storage. Compressor efficiency is less of an issue if you are running an off board compressor.
