New to A/I - a few questions
 

Hi there, I'm really new to this so you'll have to bear with me. The first thing might make me sound like a moron but please if you disagree could you please explain why.

I'm looking at A/I strictly for reliability. Lower temps, knock suppression, steam cleaning carbon deposits. I have no intention of using it to suppress knock for the purpose of running more boost. Simply for reliability.

From what i'm reading around, primarily on aquamist.co, not alot of people do this. The tuning discussions go on and on to the point where i'm thinking I can't just have the car tuned sans-a/i then start running a small amount of (probably just distilled water) on top of that.


The next thing, I noticed there are two different means to actually "turn on" the injection. One is at a certain boost level, the other has directly to do with fuel flow (i saw this with aquamist.) I haven't yet read which one is more beneficial, especially towards a rotary application.



As far as actually setting up the injection, I was reading on the aquamist forum I believe, and what I have jotted down here is that the steps for "tuning" it are to
1) Work out total fuel injector capacity.
2)Determine water/meth ratio
and then since I was thinking just distilled water would be best for such a simple use, it suggested a 10-15% water to fuel ratio. Then I'm quite sure I saw something on the site suggesting that this might be too high. I would probably want 8-10%?

then this is where i get really confused:
It discusses injector capacity. I am currently on stock injectors and will be for a light pfc basemap build. Would total injector capacity be the 850cc secondary, the 550cc primary, or the combined 1400cc combined? Then would one take into consideration the injector duty cycle which will be roughly 80%?

Then to confirm, lets just take me initial assumption that it's the combined 1400cc. This means i would need 140cc pump and a jet corresponding to 140cc.

Then I have quoted from the source:
What does this mean? lol


One more thing i haven't been able to confirm, is .. is the injection either "on or off" or is it like a throttle where it can run a certain %duty?


I initially thought this would be as simple as buying a kit, setting a boost level at which it activates and turning it on. I am a bit overwhelmed :facepalm3:

I realize this was a very scattered post but thanks in advance for any and all help

just hook it up to a boost switch (Hobbs switch) with a small jet and put some distilled water in the tank. When you spray it you might feel a slight dip in power depending on jet size. otherwise not a whole lot will change.

it doesn't have to be that complicated unless you want it to be. for your purposes you don't need a lot of cost and complexity
