what do you think the gains will be doing this system over just a MAP switched (on/off) kit on a 12psi max car? i'm basically wondering how complicated i should get on such a simple system i have going now. if just a Hobbs switch will do it, i'm all for simplicity.

read through this, looks like an interesting (and cheap!) system..

Work firewall blocked it, but any kind of controller that meters the water based on how much air is going into the engine is a good idea.

It'll work with just on/off, but controller will help when you're tuning your a/f.

I was originally going to to try to work out some kind of variable resistor set up on the throttle body and have it control the voltage to a pump. I'd need a nozzle that would maintain a fine spray through a range of pressures, like it would need to have a spring load or something.

No tech, but I have ran about 1.5 gallons through my cheap ebay kit and it is working great.

In response to the initial post:
I just thought that I would clarify that a combustion reaction is actually a exothermic reaction.... exothermic meaning that heat is a product i.e something that is created by the reaction. e.g. Combustion gives of heat

An endothermic reaction is when heat is a reactant i.e. some that is used up in the reaction. e.g. The melting of ice uses heat as a reactant and would be considered endothermic

well I have as 300zxTT stock turbos greddy intercoolers profecA set at 10 with out water meth with 50/50 I can run 17 and still not sense knock the motor is fairly fresh and I haven't wanted to push the boost any higher but I use a combination intake temp and injector pulse trigger and inject the mix into the charge pipes before the intercooler and just behind the throttle plates using an .08 in. nozzle @ about 350 PSI the mist and droplets are so fine it almost vaporizes immediately and reduces the intake charge temp from around 160 F down to about between 90-100 very effective the secret is to make the finest mist possible to remove the heat from the incoming air any other benefits in the aid to combustion are just gravy

Hey all its schwitzer turbo here, last my password and my email account. but i did eventually run this setup succesfully @ 1.8 bar for almost 10 000km now

1500cc sohc 12valver @ 200kw 400nm FTW! (now lets try get sum traction)
