well, since i plan on running 20+psi when i build the new 7m, i was thinking of using this. however, i would set it up with a hobbs switch to kick it on prolly ~10-14psi. that way it wont be on all the time and since ill have my turbo timer set up by then it will always idle a few mins before shut down and the water wil be off so it shouldnt be a problem. now, the issue with that will be i will have to find a sensor to install on the water reservoir so that when it gets low it can turn on a light so i dont go boosting without any water and melt something. i could easily mount the warning light on the dash in plain veiw.
