I noticed that many discussions are on this board about water injection. I own a WRX in the US that I use water injection on. I had used water injection on and off throughout the years with good success especially on high compression V-8's both in automobile and performance marine applications. However I just recently began looking into exactly how and why it works and why it has been helpful to my tuning these last couple decades.

I have posted a paper on the topic here: Water Injection Paper

Feedback from other performance enthusiast boards have improved it significantly and I hope to continue to improve on it from additional feedback.

Lastly I just started a forum here: Water Injection Forum for anyone that might be interested in contributing to the topic on a noncommercial site dedicated to water injection without focus on any particular make or model application.

I will follow this thread as well for feedback especially if it comes with support to help me document things.

Regards
