I just purchased a Snow performance 2 stage kit and will be installing it in the next few days. Looks to me like dialing it in is the hardest part, pressures and nozzle sizes etc. I am going to take a conservative approach, especially after reading this thread. One question I have is what mix of meth and water is in washer fluid and does it vary brand to brand? Sorry if this was already mentioned, its such a long thread its hard to find things here. Thanks----
This may seem stupid so please shoot it down and tell me what you think.
This is all for the reason of saving money.
When I had my VW VR6 supercharged i was running 15psi and needed to run water/meth, back then I made my own kit using a washer tank and pump and discount auto parts washer fluid sprayer slightly adjusted to control flow. Now on this (much cheaper car) I didn’t mind experimenting but with the ford I would rather get some other opinions.

BTW it worked perfect on the VW.
The basics of it are the same, and it would not hurt anything, however, a windshield washer pump will not function at all on these trucks. The pump must build enough pressure to overcoome whatever your boost pressure is at the time (ie, 15, 20, 25, 30psi, ect) AND still maintain enough to actually inject and atomize the water. Im not sure how well an automotive washer sprayer would help the water mix with the air, but I can tell you the pump will not build anywhere near enough pressure for this application.
There are several ways to do it. Sit down with some popcorn and read this entire thread. You will learn WAYYY MORE than you will ever need to know about this subject, and there is plenty of information here on sources for the kits, or methods and parts for constructing your own.
Glad to see more people are opening up to this. Tim, you think it is deserving enough to be sticky now?

Not sure i understand why you need a high presure pump. Is the idea just to get the spray/mix into the intake? Or does the pump do something special.
Sorry for the questions but trying to save my self some time reading this thread all over again.
ur boost will be at 120. so u will need a tank that can handle 150 or so.
You might get a air pressure tank and weld a new filler neck from 3" steel pipe threaded to accept a cast iron cap (pipe type). This would be inexpensive and would hold sufficient pressure. An aluminum tank that would hold that much pressure would be expensive and probably a custom fabrication from plate with outside reinforcment.

Since you have to inject in the pressurized side of the intake, the water pressure must be more than the boost pressure or it will get forced back down into the pump, and nothing would come out. Just physics.

You have to spray into the pressureized part of the intake system, just before the intake manifold. Otherwise the water will become liquid in the intercooler . If it becomes liquid and reaches a cylinder in liquid form...BOOM...destroyed engine.
You can't really compare the type of system we are talking about with the windshield washer pump system. We are talking about pumping a lot of water. Read the first two pages of posts and get a better idea.
i think i understand now. Lets see if i can break it down more.
this is how i did it in the vw i had the holes toward the intake actually right at the TB and a button controled the pump. If you only use this wide open the 38psi should push that mix right into the manifold?
So the boost is rushing right past the small little jets at the TB and you feel that its time to cool things off a little. you hit your button and the meth/water sprays out of your rig job and runs into the manifold and there it is. Its that easy..... i wish!!

If the nozzles were on the pressurized side there was NO flow...See if you can explain a little more carefully where you placed the nozzles.

My boost gage reads 35 PSI at full throttle and load. My pump makes 70 to 100 PSI at the nozzle. This means I have a net of 35 lbs at the manifold.
