[QUOTE="M30, post: 315999, member: 3233"] Sorry but I don't think i am misleading because the article here which i had read previously said that is it caused of the water hitting the fast moving the blades. [B]Spray Location[/B] As described above, this system injects water in front of the air filter, at the engine intake. As far as we know, no other water injection system attempts to do this. So why do we? [IMG]http://us1.webpublications.com.au/static/images/articles/i1103/110369_5lo.jpg[/IMG] Firstly, one of the problems of before-turbo water injection is potential erosion of the compressor blades by the impingement of drops of water. When the turbo is spinning fast, such impacts have the potential to strip tiny fragments of metal off the blades, over time pitting it. Whether this actually occurs or not is open to question – but it is a valid question.
