hasn't anyone ever used boost pressure to feed water injection pre-turbo? I've read it, never done it but sure seems simpler & cheaper than all this electronic crap..
I know this will start the " it'll screw up the compressor blades" argument ,but will it? will it really?? how many ppl run draw through for years without damaging the compressor blades...
those who can, do
those who cant, teach people on discussion boards and impress themselves with their own high post count

I ran it in a drag car. Ran slower in the 1/4 than before. But didn't rejet or anything. I guarantee my electronic stuff will out perform it, 100%. If spraying a shot of pure methanol as an octane boost is all you are looking for, then sure, its extra octane, whatever. The cooling effect comes from the fine mist of water flowing through the intake. Not gonna get a fine mist by squirting a squirt gun down the intake.

Boost pressure generally isnt high enough to atomize any sort of water/meth mixture. As Chip said, the best way to get the full effect is to create a fine mist. This takes a decent pressure from a reasonable pump of around 150 psi or so coupled with a correctly sized nozzle.

I opted for the electronic 'bells and whistles' version because I like the idea of injection that ramps up and is adjustable from the drivers seat while being a digital boost gauge at the same time. Looking at my kit, almost all of the parts are things that can be found searching around the internet with the exception of the gauge/ proportional injection controller. You can still fairly easily build your own such as Clonebug or the guy at this link did: http://www.turbomirage.com/water-alcoho ... -list.html

I ran it pre-compressor for 10 years with an Edelbrock system. It eventually did erode the smaller diameter part of the wheel. I am still running the turbo with the eroded wheel, but switched to an AEM unit that sprays in the intake plenum ahead of the throttlebody. Much better now.

Ok, so I looked up the prices on the pumps suggested in the site above. Most are above $200 mark. Ouch. Tell me why I wouldn't try something like this?

After all, I get 8% off if I buy more than 2 of them. :lol:
