DIY water alcohol injection setup!

My idea as picture to clear it up.

Idea there is same than in your Oil separator- design something unique,
and save hundreds of dollars/euros whatever.

I see your idea above, how are you going to get the system to flow by boost pressure? The pressure in the manifold will be equal so there will be no pressure difference to force the water in.

Yes there. Thats why we inject it before turbo starts to make pressure.
Until turbo is on full work, we have pressurised tank, whoes pressure
will overpass pressure on manifold.
Actually.. That way we could do "stage1" so at it will flow when turbo pressure
isnt up, and add mechanical switch, which controls magnetic ventil on pipe line, which will be controlled via
gas pedal, so at everytime you smash it to floor, it will open
pipeline, so it flows. When turbopressure is same as in mixture tank,
flow will stop. And we can add timer to magnetic ventil, so it will be open always like 6secs (just idea to clear my thing) and then it requires new signal to open again for next 6sec, and signal will be given when you take your foot out of gas pedal, and again smash it to floor. Simple.

Damn i just solved my problem how to control that magnetic ventil.
Solved it on previous post. To roll, where the wire from gas pedal comes, will be assembled copperbolt, which will be electrified, we will give really small controlpower to it, under 3A.
Now we imagine the roll is on "sleep", so gas pedal aint pushed, and the wire isnt turning the roll yet. Some way ahead of the bolt, is counterpart,
which will counter to that bolt. When the bolt slips over it, it will close electricity circle, and that small controlpower will wake kemo-switch (kemo-switch is like turbotimer, it will give power from battery for selected time, but with it we can use like anything to give it signal, like that 3A control power, which will "flow" only way under 1sec, but it is enough, it will activate the kemo) which will control magnetic ventil. Damn, solve was ahead my eyes and i didnt make it until now. That thing can only work (selfish).

Please point me where im going wrong, or what wont work,
i cant notice all myself, for me that looks "perfect", stage1 plan.

I don't know how much power or help it will be off boost but its worth a try I guess. Seems like alot of work for an unproven system though. It would be nice if you could set up a pressurized tank first with some simple switch, and pressurize it with an air compressor or something before you go to all the work to setup/wire/fab the system only to find it doesn't make the difference you hoped for.

Since you are already using a windshield washer tank, what about using using one that has a built-in pump? Would that supply enough pressure?

[Jason]

It might, but I like using boost pressure so the flow is proportional to boost. More boost equals more flow, where the electric pump will only pump a given amount which may be too much or not enough depending on boost and rpm.

Jason

Except using turbo boost to pressurize the tank means there won't be any flow since the pressure in the tank will be equal to or near the intake. Then in best case the low pressure won't atomize worth anything.

[Jason]

Thats why I was injecting it before the turbo. No pressure there. I got a more noticeable increase in power from the front mount intercooler though. I think I would do that first. Back when I did this, it was a cheap setup to try out and see what would happen.
