vented carbon hoods
I see a lot of vented carbon fiber hoods for sale from various manufacturers and of various styles, but how do people keep it from raining on your engines? are there some type of gutters installed, or do you just let the engine get wet?

I've had the rain gutters off my car since I got my vented hood, no issues. If you look into your engine bay you'll see you're going to get more water in there from below then what will fall in from the vents.

excellent info guys, just what I wanted to know. I prefer the looks of the vented hoods as well as the idea of a cooler engine bay, just wanted to make sure. thanks again.

my factory hood has a dent, but I've always liked the look of carbon fiber. perhaps I'm a poser, but I'd like the CF hood just because I like it, even with no other reason. I'm still shopping brands though.

Ehh I have no idea what rain would touch but there's obviously connections down there that would get wet. I found some of them and wrapped them up my best with electrical tape... But I think the benefit of how much heat escapes is worth it, especially on hot summer days with 100 degre heat...

I've driven my car in downpours without the gutters and have had zero issues. When you're driving at speed most of the water doesn't even fall into the engine, if you look at how the vents are cut there isnt a straight line for rain to get in there. At highway speed the air basically pushes the water away from the vents.

easy fix for that is to use turtle wax ice on the covers. It's one of those synthetic wax meant for paint (dont use it on your paint). It does work great on the black plastic of the car. I put a coat on every 6 months and it stays shiny and easy to clean off the whole time. it also keeps the water spots from forming.

I didn't have a temp gauge till after the hood. Expo has a thread where he simply raised the back of the hood up a half inch and saw declines in temp. I would have to assume 6 large vents would do even more.

Having owned a Seibon KS, I'm not really a big fan.
A few reasons:
1. Heavier than stock hood.
2. Hood flexes and bends over bumps.
3. Doesn't reduce engine bay temps while the car is moving.
4. It can reduce engine bay temps while idling in traffic, but it's minimal. Your engine has no load at idle, so it's useless.
While rain gets into the engine bay - it really doesn't hurt anything.
My conclusion is that the only reason you should want one is for bling. It's useless otherwise.

While I'm not disagreeing with you I'd like to see some proof or data on these points.
1) your hood may weigh more than stock but others may not. Mine seems to weigh about the same. Different hoods from different batches can
weigh more or less.
2) as in #1 your hood may of been made poorly, mine doesn't flex over bumps at all... I've had no problems
3) I'd like to see data on this.
4) I'd also like to see data on this, I don't see how it would be minimal... I see tons of heat escaping. Data or evidence please.
I'm not disagreeing like I said, I would just like to see proof or some type of data behind this. For all we know you could just be making this up...
