When I stopped and popped the hood the water pressure gauge was reading only 30psi .!!!
I have since installed a little system to monitor the water pressure , yes I know that I could use a gauge but , I dont have room for another (I have 10 additional gauges in my 7) and during a high boost , high speed run , gauges are the last things I look at !!.
What I put in is a pressure switch that triggers a relay when the pressure falls to a preset low .This illuminates a warning light and simultaneously kills power to my boost controller to allow the wastegates to immediately reduce the boost to 3.5 psi .
When I get the DDS2 I will have both pressure and flow protection , hopefully saving me from another disaster . :?

At what pressure is your sensor set to activate the warning indicator? Is it an adjustable sensor or fixed setting?
