I have a few questions about these setups. Any further info would be appreciated too.
Question 1) Is there a company that makes a decent quality complete kit, readily available? I would prefer a decent quality kit. What value are these?
Question 2) Are they easily made up if you decide to buy the parts individually?
Question 3) How do you reduce the risk of corroding the Aluminium, can you get an inhibitor mixed in with the water/methanol?
Question 4) I assume the solenoid injector is mounted between the throttle body and supercharger unit, does the mist have any effects going through the supercharger rotors?
Question 5) Obviously these are best run on a trigger switch that relates to the throttle position, are there any points in the throttle position where its best to have the injector and pump turn on, IE 1/2 throttle, 2/3, 3/4?
That is all for now.
Any answers would be good, links to other posts or sites about these would be good too.

To answer some of your questions Mike
1. I am using a Devils Own kit, there is also Aquamist, Alcohol inj systems, Coolingmist to name a few. 2. Yes. 3. What ally is going to corroded 4. The system can be controlled a few ways, with a Hobbs pressure switch, through an aftermarket ECU with a boost reference, or a controller like the one from Devils Own. The injector on mine is mounted pre throttle body and has no effect on the rotors. 5. It is controlled by boost pressure not throttle position
If I remember I will post up some pics on the weekend, do a search on any of the ones I posted above
A good quality kit with an electronic controller will set you back about $450 from Devils Own.

You need to use boost as a trigger not TPS options as Paul posted.
The injector is called a nozzell, I suggest the devil's own kits and in particular the nozzell they use is the best way to go.
If you buy all the parts on there own they add up to just as much as a kit.
If correctly setup it will have atomised the water meth and it will not damage rotors or cause corosion, high pressure pump is essential, lots of kits use 100psi but 250psi provides better atomisation.
Injecting pre supercharger is essential to help cool the rotors and housing, preventing heatsoak.
It is advisable to inject pre throttle body as you need a solenoid for post TB positioning adds extra cost with no performance benifit.
I would recommend Devil's own kit, good price, great nozzell, good connectors and very good quality 250psi pump.

Alright, thanks for that guys, pretty much what I was wanting to hear. I actually came cross the Devils Own kits a few weeks back, and they seemed the way to go from what I read up about them, I was actually going to ask about them.

3) yes
Care to elaborate there Dan?

Ah of course, that makes sense to have it before the TB to remove the vacuum pressure complication.
Thanks guys.

Keep me updated Mike, regarding our discussion on the M90 and further mods - you mentioned Meth injection, Be interesting to hear what the results are like & how much it costs to get all setup.

I run a snow performance water/methanol stage 2 kit and it seems to work very well.
Easy as to install and mine is controlled by the controller unit that comes in the kit and is triggered by boost. Mine comes on at 10% spray at 2.5 psi and is going 100% at 8psi.

I used the devils own kit
Used the front washer bottle as a reservoir and mounted the pump to the impact bar.
This is the controller.
And it is feeding this.
I am using the 3 gallon/hour nozzle and have the pump set at 200 psi.
set to come on at low boost mainly to clean the combustion chambers at the moment so that I can get some more timing into it later and reduce the possibility of pinging and damaging another motor.

Do you guys really really need the meth mixed in?
About ten years ago when I was playing with a turbo Z motor, I found it was just as happy on straight water.
Methanol reduces the surface tension of water and allows for smaller droplet sizes. This allows for greater cooling less chance of damage particularly important when injecting pre turbo as well as methanol's higher octane rating.
Due to the higher pressure pumps currently available droplet size isn't a big issue but smaller droplet sizes are still regarded as better.
Methanol is cheap, available from many locations and is used in windscreen washer fluid it isn't a big deal to source or to use.
Typically 50/50 mix results in the best power output but optimal cooling is achieved with a 70/30 mix of water/meth according to data provided by water meth kit suppliers.
