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.

Looks like a bottle rocket I had as a kid, bit more pressure there though.

hahahahahaha! poor Bo

I don't understand the pressurized air delivery system...?

Fill tank with liquid. Hook up to convenient in-trunk 70psi air delivery system. Tank pressurizes. When valve (feeding off bottom of tank) is open, liquid is delivered under pressure.

In the pic above, big red handle is the ball valve I fill through. Gauge and schrader valve can be seen on the other side for pressure.

Small fitting with orange plug is the water outlet.

Pressurized water is delivered from the tank (in my trunk) to the TB through a filter. TB with nozzle is here (a couple years ago):

Somewhere around here is a video of the nozzle spraying. I can't find it any more.

EDIT: Found the vid:
