water injection Options

Actually, when your EGT's are too high, it's more advisable to spend the money for injectors and fuel control or turn the boost down.

The water should cool the air charge down before it gets to the combustuion chamber, and I have heard that it cools the exhausting gasses as it uses energy to turn the water vapor back into a liquid. The bad side effect to water injection is that it takes up space normally ment for gas and air. So what it does, is slow the burn which makes a cooler combustion at the cost of performance. The only thing that makes it worth while is to offset the lesser performance by pumping up the boost. This is also the same theory used when you put in race gas. It actually burns slower (less performance) than regular gas, but allows you to add boost and or timing to make up for and increase upon the difference.

So if you don't have the fuel to turn up the boost, you may actually be making your car slower. That's what I meant by a waste of money. Not for safety sake, because a slower less performance oriented burn will definitely be safer for your engine.

Take all this melarky with a grain of salt, because I'm going by memory. Nate and/or Kris may be able to shead more light on this.
