Im planning on running a water injection system in the near future. I found vid on youtube for a preturbo injection set up that looks good and the guy says someone on here sells it. I think its (dude man zone) he said the name was. Do you guys have experience with water injection systems either preturbo or any other variation on S5 FC? What brands or systems work best?

 

Look in the AI section or search Howard Coleman. There is plenty of info.

 

The AI section is a wealth of info. Although, I get lost in there sometimes as well...

I'm in the same boat as you. Looking to run AI, and was debating on running pre-turbo. From what I've read, there's mixed opinions. On a stock turbo it's less of a concern, as they can be had fairly easily. So fin errosion isn't really an issue. Apparently it gives you the best bang for your buck though.
