RAIN , RAIN , RAIN
I have seen countless air hoses/ducts connected straight from the radiator support or grill to the snout of air cleaner . I did a S-15 that way !
I believe it works great , and will most likly do it again well it seemed to from radiator support straight to air cleaner .
My question is it seems to me water would be terrible for the carburetor/throttle body !!!
Water almost had to be getting into the carb because I went through an enormous typhoon and truck never sputtered once . I was on a 4 lane moving fairly fast with no traffic and could barely see for the water so water had to b getting into throttle body .
What you guys think , is the water not actually getting into the carbs ???

Obviously not too much water was getting in or it would have snuffed your fire...and maybe caused hydro lock. Lot of cars/trucks are set up like you describe to get cooler air away from the engine compartment.
A little bit of water will actually clean your combustion chambers. It turns to steam as it hits your hot air intake and "steam cleans".
Burning gasoline, (or wood, paper, natural gas, etc) actually creates a little water which will get past your piston rings and end up in your motor oil. That's why it's important to have a T-stat that gets the engine warm enough to chase the water out of the crankcase.
Some tractor pullers will actually set their engine up to "sniff" a little water mist to cool the air charge and make more horsepower. It's a fine line and not for the faint of heart.

It is ghetto as all heck but I actually run an intake from the factory air cleaner through ducting that is placed between the rad support and passenger headlight in an attempt to pick up some cooler air. I pulled the idea from the old school Ford racecars that had the ducting going to the headlight holes. I have noticed absolutely zero difference rain, shine or snow with performance. Also, what little water does get in there is negligible at best.

Looks just like a headlight hole
Looks to be factory I do not know !!!Evidently not much water gets in
I plan to run dual turbos
........one day........and want to run duct to , well they r fed from the exhaust 
, well mayb from the other side ha ,I get a little confused sometimes
Turbos have to have fresh KOOL air from somewhere
& I was concerned about water getting in the turbos also

I believe that fancy spray can stuff , Seafoam or what ever it is called is just water !!! .
Old timers poured water straight into carb to de-carbon engines , & it smoked just like that Seafoam stuff

I use to have one of those Neon SRT-4's and to my surprise the hood scoop was actually functional and fed directly to the turbo. I drove that thing like a scalded cat in the pouring rain all the time and it ran just fine (I think it even asked for more at one point). You need to get a TON of water into the intake for it to really cause a problem. Like the time I had a cold air intake on my first car and thought I was the bees knees only to run through a very deep puddle and hydrolocked the engine.

Starting somewhere inthe 80's the factories run the air intake out to the radiator support to pulling cool air.
My 81 F100 is that way from the factory as was my 86 K5 Blazer with a diesel that I installed a Gail Banks turbo kit on at 100K and ran it another 130K till I sold it.
Yep rain snow you name it no issues.
BTW if you run a paper air filter if it gets too wet it will choke off the motor before hydro lock unless you drive into a lake
