Hiya Mate,

I have also been looking in to water injection and i make intercoolers for a living. My concerns with fitting the injector before the intercooler would be as follows. Intercoolers are designed to cool charge gas. To do this most efficiently, the gas / air has to be slowed down as much as possible to allow maximum heat transfer between gas and heatsink. When you slow a gas down, any molecules being carried in suspension e.g. your water, will tend to condense and fall out of suspension. I would think this would result in a tendancy for water to build up in the intercooler. My concern with this is, hydraulicing a cylinder. What happens if you motor suddenly gets a cup full of water. Another concern i have is, with a single injector, how do you assure that all cylinders are getting the same amount of water vapour? We all know that even through the best intake manifold design, the cyls closest to the intake get the most air and the ones further away get less. This would apply to the water as well. For my own vehicle i am looking at four injectors, one per cylinder. There are places on the net that advertise these. They would probably work with your existing setup with monor modifictions.
If you are not using aquamist, which type of water injection are your using? Just interested to know. I have my Escort in Zimbabwe, Africa and when i buy something from your neck of the woods that doesn't work i get a bit pissed off 'coz it's a bugger to return. Hope this helps.
