Question What's the skinny on water injection in a turbo engine?

I'm curious about this. I've seen water injection systems used in aftermarket turbo applications. Specifically on an acquaintance's turbo 88 Fiero GT.

Are they a bandaid, or are they a handy thing to have?

I understand the basic principle in what they do, cooling the combustion chamber temps, and also steam cleaning the chamber, but don't have a lot of practical experience with them.

Thumbs up

Some people feel that they are indeed a bandaid I myself feel that they have a good place for use in High Boost turbo motors better safe than sorry in my opinion. But I do feel that water injection is no replacement for good engine management tuning, a well tuned engine will always outperform a poorly tuned engine running water injection running similar boost levels of course. Check out www.22b.com and do a search for water injection you will find all you want to know and then some really good thread.

Yah the fuel management and sensible amounts of boost are always the best places to start with. After that if you decide to add more or increase boost for auto-x and drags then you might want to use the water injection. The reason is alot of people have forgot to refill the water tank and then risk the engine. If you can find one with a water level gauge for inside the car then that's a big plus. You can buy a complete kit from the UK or you can do what a friend with a Grand National did and buy a setup from the Aquamist company in NJ. His was set so that it would only come on at a certain boost level. It was really nice for the drag strip when he would want more boost. There are alot of other rumored benifits of the systems like cooler running, better emissions and things like that. I know in Europe alot of car companies (including Ford) use them as a standard feature.

So, then when you stop for gas you stop for a water fillup to? hmmm I'm sure I will forget about my water spray bottle for my IC once I get it in. But then agian maybe not. Just more stuff to deal with in the long run.

Check out www.mrtrally.com.au they have larger tanks that are installed in the trunk. They add more weight but you won't have to fill up as often.
