Noticed the last couple days that the post-IC temps had been rising. The EGR was the unknown factor in my intercooler setup. Time to clean it out (or at least see if that'* the issue) before I bypass my EGR to keep the core clean.
Time to clean it out for use. The nice thing is that I can open my cutout, and none of the 'gunk' the water injection breaks loose will go into the cat.
Some vids for humor, and a demonstration of my pressurized air delivery system in action (the WI nozzle is still in my ported TB on the Zilla):
It'll be interesting to see if my post IC temps recover after a tank of water/methanol mix. If it does, my EGR suspicions are correct. There'* no way to get a borescope in there for inspection.
