Tried the search feature and didn't find it. Although I'm sure that someone must have brought up this topic before.

Vented hood owners, any problems you encountered with heavy rain? I can't see it being really good for the engine to be washed down with rain - especially if you drove the car for some couple of hours. Can the heat disapation be too fast and cause things to crack? What about intake - can the cone/filter get soaked after some time and cause engine problems? I'm not talking about driving through a lake. I'm talking about those rare heavy rain days when you absolutely need to use the fastest wiper speed.

and also...how much does the vent really help?

 

I think it's mainly for looks if you think about it. If you want a vent get a Varis ar duct, that should help a little but not a significant difference IMO, or so I've heard. They look cool as hell tho-

 

Good question. I’m searching for a conservative looking hood which rises in the back (where it meets the windshield) about 2 inches. Ambient air enters the engine bay from the front bumper, is heated by the engine, rises and escapes at the rear of the hood. Rain on the windshield drains as usual.

 

do_luck hood is raised, but do not know if it's opened by the windshield

 

I was playing around a bit with this photo (Greddy) rasing the stock hood.

 

vented hoods decrease engine bay temps a lot. i carry my vent liner in my trunk in case of rain.

 

exactly...

also, most quality vented hoods come with removable rainguards

 

what does a vent liner look like and where could i get one?

 

Good job. Clean and functional. Get with one of the aftermarket manufactures, make it, and I’ll buy one.

 

its just a shell that goes under the hood against all the vents and attaches with screws. mine came with one. i removed the screws and put some velcro all around the edges and on the underside of hood for easy on/off. i never knew that any of them came without one.

 

Wow i didnt know that, I was doubting to get a vented hood because of the rain problem...

 

any pics?

 

yeah some pics would be nice. I'm pretty surprised that no one really tapped this topic before. Pretty sure we all thought about the effects of water on electrical components in our engine bay...even something like the MAF sensor. That thing is pretty sensitive and some water could cause engine to malfunction. Vent inserts w/ screws sounds tedious or at least some what time consumiing. Like the idea of velcro. How's does the glue on the velcro hold up to the combination of heat and some water? I'm assuming not much water touches the velcro but the heat is something that cant be avoided.

 

I have a Seibon VT vented hood, and the drivers side vent sits directly above my Turbonetics turbo, so this makes a huge difference for me as far as under hood temps. As for rain, I'll bet it would have to rain REALLY hard for these vents to actually pose a threat. Your car can tolerate alot more water than you think.

 

ok, i'll go down and post pix later tonite.

 

Z-Boy
What hood do you have? Because all the Seibon vented hoods don't have rain guard.

 

But doesnt it get kind of dirty in the engine bay even if it doesnt rain much?

 

vis.

 

Well, my car is a garage queen, so it's hard to say really. When I wash my car, I always wipe down the engine bay, so it stays pretty clean in there. Doesn't everyone detail their engine bay?
