Guy, I'm considering adding a flapper valve to make the ram-air effect greater...has nothing to do with the water. The water droplets are just a result of high pressure air from the airbox "leaking" out at speed. The flapper would allow a build-up of pressure up to the point where the motor needed more air than available from the two front inlets...then it would 'flap' open and allow the engine to breathe freely. Most seem to think that the airflow through the box, as OEM supplied, is to keep the airbox cool and allow another inlet for high rpm/high load...but it doesn't do a good job at allowing a true 'ram-effect'. The difference?...who knows.
Be good,
