What everyone needs to know about water injection is that you have to be running AT LEAST 17 PSI. The water won't atomize well enough at lower pressures for this system to work. It's pretty widely used in the DSM circles. It only costs about $300 to install, and it's worth nearly a hundred horsepower on a properly tuned car. Amazing. Not only does it cool everything in the combustion chamber, but it also cleans everything out of the combustion chamber. Carbon won't stick to an engine that's running water injection. Most Hondas can't handle 17PSI on stock internals for very long (if at all). I don't think any OEM Honda head bolts could hold it either. You won't find water injection to be even a possibility with your Honda unless you LOWER its compression, enabling you to run higher boost.
Thanks, that kinda answered my question (why doesn't everybody use h20 injection) My roomie's saab is usually running between 18-23 psi, works wonders on his car.
If thats the case, though (only good for high boost), i wonder why the JRSC uses h2o inj for only 8 or so psi? :thinking:
Thanks for the info jafro
