I have the ram air hood and want to know what keeps water from entering and going all over my engine ( at best) or worse down my carb during a rain storm ? Yikes what about going through a car wash , which I won't do anyways but just a thought?
Which keeps water out of the intake, but drops it right on top of the distributor. p A good heavy rain or a car wash can soak the distributor, and the car won't start until you dry it out.
Water injection is a good thing. It is often used in high performance engines. http://en.wikipedia.org/wiki/Water_injection_(engines)
I had the water on the distributor problem for awhile. I filled in all but the front (towards bumper) holes with a dab of silicone caulk. This still allowed drainage but not so much it wets the distributor.
I've had a GS for few years but never drove it in the rain or when there might even be a chance for rain. If I were going to chance it, I would come up with a spare regular air cleaner and somehow plug the hood vents either from above or below the hood. Same goes for washing although I never use a hose on any of my cars, only a wet rag and towel.
I bought my wife a new car. She called and said, "There was water in the carburetor." I asked her , "Where's the car?" She replied, "In the lake." Henny Youngman
