Just setup my system with a boost activated switch since the progressive box didn't activate the pump. Also setup it up with the coolingmist 250psi pump set at 200psi. I love the ease of this setup but one thing is for sure, when it comes on it comes on hard! I've got an m10 nozzle and that thing flooded part of my garage and drained about 1/4 of my 1 gallon tank and it was only turned on about 20-25 seconds, lol. It works though I can tell you that much. Even at idle the egts were about 850 degrees and when I'd spray it the temps at idle would go down to about 780 degrees and lower. Not bad

Ey Cam, I had a dream recently about doing an M2 (with alcohol) in front of the turbo. I don't know if it'll be efficacious or not. Based on my experience and familiarity with alcohol, my guess is it won't... but it wouldn't hurt to try.

I think 50/50 would work better though. The water will cool more then alcohol under high boost when outlet temps are 250-300*F, then the alcohol would bring the temps down even more due to having a lower flash point. Smaller nozzles could probably be used and less alcohol usage from being mixed with water.
Another idea is a dual setup, one with alcohol and one with water. Use the water preturbo and the alcohol post turbo. The water could be a simple mechanical system and the alcohol pump driven. This setup adds complexity though.

Im not sure how methanol will go with your front wheel on the turbo, only one way to find out, but if you are able to get it work, id say your IAT will be shitloads better then any post turbo jet. I would almost go as far as saying as it would completely change your turbo efficiency ranges.
Also for people using water injection.
You have to be looking for the right results. If your looking for cooler IAT and cooler EGT, this is not water is best. It does cool both without a doubt. But its biggest factor, is it completely eliminates knock. this at the end of the day is what will result in your engine being stuffed.

It might work quite well with your no intercooler setup. Definitely won't hurt to try. Unless the alcohol ignites or something.

edit: damn just found a switch for 12.99 lets see about a cheaper tank :O)
....oh dang 28 bucks...

Man that's a good idea, I still have a coolingmist 150psi pump, some line, and a smaller nozzle. Now all I need is another 40 dollar tank and a 24 dollar boost activated switch...... Hum....

i need to visually see a diagram to get an idea here how the mechanical system works... im really interested and have been reading up alot on this, whp know ww2 planes ran this system lol awesome

sweet, would a boost soloniod work if fully charged? like a mac (one use for aem boost controller) idk if the ports would be to small and also risk messing it up
i just found your thread and its very simple, btw theres no need for a one way valve to let the tank relieve pressure under vac? like a breather i guess or just running open to the compressor is alright?
where are the dyno vids!!!

2 questions...
By the rate of your system injecting water... doesn't it affect your intercooler performance when using a preturbo setup? I guess the IC circuit allows the water to lose it's atomisation?
Basicaly filling the system with water.
or don't you use any intercooling?
Secondly, doesn't your water supply system need a reroute for overpressure?
more or less like a fuel setup using a pressure regulator and return line to the tank?

Further atomized by the compressor, and once it mixes with all the extra air it's moving so fast through the system it gets pushed right on through. Any inefficiency that could be caused by the water is made up by the waters cooling effects. We can really only guess what's going on in the intercooler. With compressor outlet temps between 250-300 degrees, alot of the water would flash into steam, once is reaches the intercooler it may condense back into a liquid. In any case there is plenty of air for it to mix with. Whatever it's doing it works. Granted i've never run near as much water as rx72c, but from his results i would say lots of water works too. Keep in mind you have to have a good ignition to burn a mixture like that. High boost, lots of water, and fair bit of fuel isn't the easiest to burn.
