Water injection: any experience?

I have used it. It absolutely works to reduce detonation on boost when running gasoline. It allows you to add timing and boost without pinging, which is where the power comes from. So you need to have tuning control to make power with it. Although meth is a fuel and in theory adds its own power, I've found that water does a much better job reducing detonation (assume each car is different) and so the car does better with a 75/25 mix of water/meth. 100% water is even more effective, but then you can start to see steam/froth in the oil cap.
Take a look at the Aquamist system. It has a strong fail-safe system and a PWM-activated injector, more like a fuel injector than the traditional water injection systems - so you can program the amount injected more precisely based on boost, injector duty cycle etc. (Based in Europe too...)
Do you have E85 locally? That might be a simpler way to achieve a similar (better?) effect without the added complexity. I hope to compare the two at some point....

Hi Tom, here in Italy we havn't E85 ![Frown](https://rennlist.com/forums/images/smilies/frown.gif)
My target is to have more safe and a bit better performance on my "stock" 951S; i have only Rogue A-Tune (1 bar boost).
I see that the engine is very better if i drive the car in a cold day then in warm day. I think it depends of air temperature, so if i can reduce it without more invasive mods (like bigger intercooler) i should have the same performance in warm days too.
I read that water injection system has no bad points...
