Heat extractor hood question

[Rocky918]

How is it possible to have a heat extractor type of hood and use it when it rains? Isnt water going to enter your engine bay and potentially cause damage? If so what damage will it do...

for example, how can you use a hood like this for everyday use?

Good question.

There was a guy here driving in the rain with that type of hood, and his car messed up with "reduced power" because water got into the engine compartment. Don't do it unless your purpose is to drive during sunny days, but how can you so sure the weather won't rain?

Everything inside your engine bay *Should* be weather sealed. I know from being a mechanic that just about ALL electrical connections are weather sealed. That should take away a big chunk of worry

If you look at the bottom side of the hood you will see heat vents highlighted in the red box, this is not the same hole as the extractor on the top of the hood. The bottom vents are offset from the extractor and are set into an air box molded to the bottom of the hood with the vents having raised edges to keep water out of the engine compartment. Any water would drain to the outside edge of the air box where I would expect to be drain holes.

I see that it is not the same as the top, but how do you know they are set into an air box molded to the bottom of the hood to DIVERT the water? I do not see that in the description....

It should not matter. Everything under the hood should operate when completely soaked. When you drive down the highway in the rain in any car the rain goes straight through the radiator and fans and hits the front of the engine. There are many, many vehicles with open engines - aircraft, marine, auto, motorcycles.

i hope this is true, but it contradicts what someone else said

I gotcha - I'm in "WET" Florida too... But all factory cars go through rigorous water testing. If not, the amount of cars dead on the side of the road during rainstorms would be staggering. Now if you drive in DEEP water where there is a low air pickup, then all bets are off - you can end up with hydraulic lock. BTW most any vehicle with a snorkel attached to the intake can run with the engine submerged assuming you have the breathers attached too.

I'd be worried about water being dumped onto the air filter in a CAI system. I guess you could get one of those hydroshields, but I'm not sure.

The air filter is pretty much sealed in a CAi.inc one http://www.google.com/imgres?imgurl=...:0&tx=82&ty=87

Here is the thread I was talking about. He took down the link to his hood with scoop but it was similar to the one on this thread. The information is out there, now it's your move.

couldnt that perhaps be a fluke? he did say it was a small amt of water VAPOR that caused the problem, not a flood of any substantial liquid

I know that you can order special trays that run off the water to else where, the vette's have em

The "Vent Trays" are actually “Drip Trays”, they do NOT prevent water front entering. They just allow the water to drip off to the side fender cover. They are made of sheet metal and come as a pair, one for each side of the hood. We recommend the under side of the hood and vent tray be painted to match. This will give a more finished and clean appearance.
