Anyone thought about making hood ducts real?

[Disco]

Picking up an old thread:

Can someone explain why letting water directly into the engine bay at the vent holes is a bad thing? Water gets into the engine compartment already, through the radiator and splashed up from underneath. Everything under the hood is waterproof. Where the vent holes would be located isn't over anything really heat critical like the turbos, so I'm having trouble imagining why it's such a thing to be avoided.

Please educate me. I'm willing to learn.

Intuition tells me that a bit of water splashing up from the road, and an even smaller bit of water via the cooling system giving off moisture/steam, is not in any way the same thing as admitting actual water from a torrential downpour, or melting snow, etc. Having actual running water flowing down over the engine components from above would be a very bad thing: over time, if not in the short run.

Ah hah; something I've been thinking about recently (this bumped thread allows me to describe it):

If in theory the two fake vents were opened all the way up, admitting hot air from the engine room, that wouldn't ever be a bad thing: cooling is always good at operating temperature. If someone designed a true vent insert that was open to the rear, like a reverse scoop, such that the hot air went out; and the shroud stood "proud" above the hood, that would accomplish the purpose of the design. The problem would be water getting in through the vent hole in the rear of the shroud. But if there were a catch basin directly beneath the opening, with a length of tubing acting as a drain, this would answer the problem of water getting in. Even a torrential downpour would be drained off. The Korean aftermarket "vent" is plenty of good with draining (Anyone thought about making hood ducts real?), but totally blocks any engine heat escaping, because the catch basin fills the entire vent opening. By shrouding the vent yet leaving the rear open, heat would get out and water would not get into the engine bay, because of the catch basin being only at the rear.

Unique for sure but how functional of a vent is it if it sits that tight against the hood on the underside?

Only install it when it rains

Could you ask for potential overseas buyers? I would buy this I am in the states!

 

[xot1]

The parts only? The shop usually charges for the product and the labor.

I am located in United states lol not Korea

Hello all I read this thread and it reminded me of a video i watched of a carbon fiber hood put on the car with a functional hood vent, you can see it here but skip to about 7:15 in the video, Not sure if i would do this living in New England because i can just picture snow just sitting in that crevice and being a B**tch to get out, but maybe you guys in warmer climates are looking fro something like this.

There's snow all over the place in that video location. But, water drainage? Where does the water go? He said, "On the cover portion that's under the hood and drained away from the engine". I can't visualize it. Heh.

Yeah, I couldn't really picture where the water was going after it hit that cover under the hood. I did see the snow everywhere but personally, I wouldn't, not with that style anyway.

where you get these from? Amazon, ebay?

I can answer faster than he will: these are custom made in S. Korea. I don't even know of anyone in the States (much less Aus) who has put these in.

until I'd get a carbon bonnie with ventilation...as Thanos says..."fine, I'll do it myself"

This discussion reminds me of a classic Simpsons moment:

It rains in warmer climates too... Think FL for example. Maybe a desert area mod?

With the "functional" vents in my sbgt hood the rain drains are directed to the front shroud. No water "technically" hits the motor directly. Even washing the car you can hear and watch it come down up front. Im in Fl so yup lots of rain at times. Ive never had an issue. I cant speak for any the others though. I did however look at the TS hood and it too drained forward to the shoud.

I was told as a precaution though when i purchased the hood that if i decided to run without the rain gaurds in that i definitely should put hood pins in. Due to more potential of air lift, and well, the hood leaving the premises.

My assumption is that with the metal hood that concern may not be there.

I've seen pictures of a couple fiberglass hoods delaminate and it wasn't pretty.

Funny you should say that, I though if you drilled out the holes and glued a piece of fine stainless mesh behind it it would look good and not let water in but air out. Who’s game?

Me, that’s what I want to do. Let me know how it goes and what size bit you used.
