Well for sh*ts and giggles I put on an old pressure gauge I had lying around, and with no flow at all (max pressure, full slippage I guess) it only went up to about 40psi, if that.
LOL, maybe if one could find a nozzle that fogs under 40psi, maybe one could run an on/off
pressure switch and actually have it working, but how well and for how long, who knows.
I'm so close to getting the universal stage two but no one has answered my MAF/MAP question in another thread...
