Hi LAGP,
Real serious build you going on there! Really like some of your solutions. Wish I knew about the water pump housing with electronic thermostat before. Don't know if or how I would be able to incorporate it in my build but I have been looking for a electronic thermostat option for my build.
How did you seal the hose coupler for the throttle body? I might need to do something similar to mine. Right now I have bonded a strip of silicone rubber sheet to the inside of my coupler to grab on to the 3.0 TFSI throttle body.
Regarding my crude PCV solution it seems to be working OK for the moment. At least good enough for me to not change it in a near future
I'll revisit your build thread when I have more time and welcome to the HP tuners community!
Cheers!!
