Okay, finished all the wiring today... it ran on a test stand prior to this, now it is running for real in all it's glory. I am so sick of the build that I am contemplating giving up brewing, selling it, and getting a bike.
I dunno... it runs very well. The stock BCS PID setting seem to work REALLY well. Whether I am running the RIMS at 9000W or 4500W, it holds the temps within .5F. Also, there was some concern about flash boiling and issues running such a high wattage RIMS heater... it isnt a problem.
The pumps are WHISPER quiet, actually you can hear the control box cooling fan above them when they are both running. At first I though I had miswired something and that the pumps were not running at all.
The heating times are insanely fast, it is the best rig I can muster... now I just have to decide if I want to use it, or move on.
