I am sure im gona get alot of go search from you guys on here lol, but I just wanted a straight forward answer and how you solved it. I was thinking some sort of flaps that shut to keep the rain out, and maybe some sort of air bypass when you have the flaps closed.

 

My dad was telling me the other day that back in the 70s when he was out racing people, alot of guys were using water injection. The water was injected (much like nitrous is) for a quick compression boost. The problem was that too much water (even a ml over what your engine could take) would blow the engine.

So saying that...I'd think that water in the engine would be bad, past a certain point. In my future endeavours with a ramair hood, I'll be adding a solenoid activated flap that goes behind the nostrils. This should look nice and smooth...not to mention keep the rain out.

 

Don't worry about it. Unless you plan on driving through a River your not gonna get enought water in to hurt the motor.

On the other hand, if you have a MAF setup, you could very easily damage the MAF with a very small amount of water, so this is a big concern.

 

Your engine can handle SOME water in the engine. WI has been done in the past, like eyecandy said, to help lower combustion temps and therefore reduce detonation. I have also heard of people introducing small amounts of water to help clean out carbon deposits; I don't know if I would try this one at home though. With some of our cars the big problem with this is the MAF. A soaked MAF can cause big problems with how it monitors air flow and can likely lead to complete failure. Remember, this is the most expensive sensor on the whole car.

When GMHTP started thier 'magnum tpi' project they found that the MAF on their firebird was toast due to a CAI kit that was letting water by on wet days. Needless to say they replaced it, and ditched the CAI kit. Unfourtunalty for them though, this was the first of a long line of trouble for that car that I still don't think they have figured out.

Am I off the subject? Oh well.
