The progressive controller went under the dash, I made all the connections, extended the wires for the pump controller and the level sensor, and found a killer spot for the diagnostic/status LED...
This is with the LED on to illustrate the point.. Hard to miss.

And it is not the least bit offensive when it's off:

The other group of LEDs at the center are my knock indicators, BTW.

Before I forget, I had the steering wheel re-covered with hand stitched leather a few months back. Turned out great, and I paid the guy about $60 for the whole thing..

Then, I removed the plenum, and started thinking about routing ideas..
(Note, a very important lesson coming up: never make critical decisions past 3am.. Fail becomes imminent..)

Everything was cool up to this point...
Then, I had a brain fart.
For some reason, I decided to install the nozzles on the opposite side of the plenum, and happily proceeded to drill & tap...

Nice to see that you can also make mistakes (I'm referring to where you placed the nozzles on the plenum)

Can you also expand on the LEDs knock indicators?
Did you start a thread on that subject?
Keep up the good work for guys like me (mechanically challenged)

Hell, I even did some trial setup to see what the plumbing would be like..
(Blue lines are for practice only, BTW. They are 6 mm, as opposed to the 1/4", which comes to 6.3 mm, and makes installing and removing very easy for trial fits.)

This morning I jumped out of the bed yelling "Laminar flow!"...
My wife had no clue what I was talking about.
I ran out, found some 1/8 NPT plugs, and covered up my shame with liberal amounts of teflon and those four plugs..
(No pictures of that.. I was a bit pissed..)

Ahem..
I did drill & tap and install the nozzles in the correct locations, of course..
And it took a bit of trial and error to find the connection scheme that I liked..

(BTW, the car is not an automatic, the reason behind two throttle cables is the dual throttle setup I have built a while back. That thing is a MUST for all hotside S/C setups.)
You can also see the 1/8 plugs on the plenum... The only upside is, if I ever need another vac/boost port on my manifold, I have four of those ready..)

Next step will be installing the water tanks, hooking them up, and buttoning it all up..
The silicone on the water tanks needs to completely cure so I can do my final leak test before I commit to anything..
Oh, I will be running straight water in this system. I found a chemical supply company where I can buy up to 50 liters of distilled water at pennies/liter at a time.
I'll post my progress as I go.

The LED knock indicators are sold at www.knockgauge.eu, and are made by a guy in Lithuania.
You can either buy a gauge, or the kit version like I did.
Buying the kit version gives you the freedom to install it wherever you like..
And the thing works like a charm.
And yes, life would be pretty dull without mistakes.
All is fixed now.
Wow... This is really cool, really! I do not know where to start with the questions.
OK so where you put your nozzles the first time... I seriously considered placing them there but I did not think they would fit. Looks like they do, just barely, at least with the Aquastealth nozzles. So I am wondering why not just go ahead and run them there? Oh wait, you have not gutted your manifold right? I cannot tell from the photos. I think with a gutted upper plenum that putting them there is a nice idea. They fill the upper plenum with mist which helps with redundancy per my other discussion. Plus, they are directing the spray right into the throat of the runners which should also be good. Makes me think about moving mine there actually.
But that aside I like where you placed them on the upper portion of the manifold. If you have to mess with it, clearly it is easier to remove the upper portion than the lower portion. I did not place them there because I was concerned about hood clearance. But again, at least with the Aquastealth nozzles, they fit.
So I am guessing your progressive system is PWM on your pump motor? Have you played yet with the duty cycles to see what the mist quality is at low percentages? I'm curious about that for sure.
I think that bending tool you made for bending the PVC is great. Why I did not think to build something like that for all of the heat gun ABS bending I have done... it's not like I have never seen a sheet metal brake before
Next time I bend some ABS I am building one of those for certain
