I am considering whether or not to fit a waterspray to the FMIC that I am putting on my Q4. My only application for it is track use where the average time on the track is approx in 15 min segments.

I have read a lot of articles on the net about them, but i have found *no* proper comparative test data that shows them leading to higher power and hence lower lap times.

I would not need an intelligent controller - as i would run the thing continuously as the races are short - so it will be simple - container / tube / nozzle / pump / switch.

but if it wont actually produce more power its not worth bothering with..

any opinions or test data/

thanks, jim.
