Alot of the guys from the shop are going this route with boost applications.
I've been hearing only great things about water/meth with N/A cars as well from alot of domestic guys.

Has anyone tried using water/meth on any of their cars?

Here is the kit:

Any feedback would be appreciated.

thanks

Water/methanol injection does make a big difference for boosted applications - you can run more boost without detonation, which is important when you are starting out with a relatively high compression engine and poor quality california fuel. The most common systems are aquamist and the jackson racing system, which is actually an aquamist as well. I have an aquamist which I'll put in my turbo RSX if I ever finish it. The snow performance system looks like good value for money, since it comes with some parts which the aquamist does not (a water reservoir for one). The pumps look different between the snow performance and aquamist - the snow pump looks like a fuel pump, whereas the aquamist makes their own magnetic coupled pump.

For NA there is no advantage running water/methanol injection. The water vapour displaces air and reduces engine output. There have been a few studies where people have measured BSFC vs power using different water/air ratios, and the conclusion is that you lose a little power with water injection but can run quite a lot leaner and obtain better BSFC. Perhaps this is relavant today with the price of fuel.

The weak point of the water injection is the pump and nozzles. Some pumps are unhappy running the whole time (the aquamist states a 1 minute duty cycle) and the nozzles are prone to clogging. Using distilled water and filters is a good idea.

Methonol is nasty. It will eventually corrode any steel it touches and eat some rubber and plastic. You much be careful not to allow any to remain in the combustion chamber once the engine is shut off otherwise the rings or spark plugs will rust in a couple of days. However mixed with water for water/methanol injection you should not have any of these problems as long as the pump and nozzles can handle methanol.

i was going to try it out in my car, not for a power adder but a substitute for for poor gas and high compression.

can water injection be used to help detonation on NA vehicles(in a way, use water as a retardant, not as air-cooling device)? also, about how much water does the water injection system consume, say for every hour. and last, could a fuel pump be used to pump water? or are there other water fuel pumps that can be used for continous duty?
thanks

Hey Pacman, would you have any pics of the intake manifold connected to the ITB's?

I've been trying to find out as much info about running meth injection in an n/a setup and can't find a lot. Some people say its great then above someone says it's worthless. Well? Which is it? I'm going to be running ~12.4:1 CR and only have 91 available here. I'd be fine just cruising around town but if I wanted to rip on it I was wondering if I could benefit from it? Any insight? This been done? Worth it? Maybe a link to somewhere explaining the entire system as I don't 100% understand it. I know it injects water/meth similar to a nitrous setup into the IM.....right? Reducing temps and chances for detonation. So it sounds usable for a high comp NA build but some say no. Someone please explain

the difference is with an N/A car running high compression on low quality fuel yo'll have to have the meth flowing the whole time the engine is running vs. boosted caars that can have it come on only when they are in boost.

regardless of what people say,im gonna get the aem kit too for my 12.5cr k24 allmotor,it prone to do good things rather then bad,as in pakistan the only fuel we get is 91-92 octane

An NA car (with streetable CR) doesn't have to run a meth/water combo, water mist will do just fine. Just be sure you are using distilled water. I know of a couple people that tuned a K20Z3 on water mist only, they were able to run 87, increase fuel economy, and made more power than they were when they were untuned on premium.

that's kind of an apples to oranges comparison though. Tuned vs. untuned??? of course the tuned car will make more power and be more efficent.
