The Ultimate Noob Question...EVVVAAAARRR
 

Ok if i get a new hood with scoops and cuts and stuff, and it rains...where or what hardware is needed to drain it away from the engine bay...?

What leads you to believe you need to?

Good discussion. I'm thinking of a seibon ts hood. But I worry about water getting into the engine compartment and rotting or rusting things

Exactly my concerns also, its just theirs a hood on the car for a reason, probably to keep water and other harmful things out of the engine.

Not a noob question, since cold water is bad for a hot running engine, specially for the alternator. Some people seal them and paint the grill black.

Some cars like Subies and Evo's have detachable panels that attach under the vents... I'm not sure Seibon does this for the 370z models, but I dunno who does make them?

Well, I think we have to understand that driving a car with hood vents in the rain isn't like taking a couple 5-gallon buckets of water and dumping them in the engine bay. It's pretty warm on the engine ... the minimal amount of rain that gets in evaporates relatively quickly. Also, I can't speak for specific hoods, but many of the aftermarket ones I have looked at in the past (for other cars) have some form of water management system.

Although, it will get much dirtier under there.

Some hoods come with a shield you can remove to keep the water out? But this all depends on how aggressive the hood is.

Mines a daily driver so we are talking car washes too.

Washing it in the opposite direction of the openings minimizes the water from getting in? thats how I wash mine with a gtr style hood

I'm too lazy to look it up (and by too busy, I mean I'm watching porn), but I'm 99% sure the authentic seibon is manufactured with rain guards.

How do you wash the engine? Water or do you need some sort of steamer?

Most carwashes offer engine bay cleaning services. At least, the ones around me do.

Edit: But if you're going to do it, do not dump water on it. Cleaning the engine bay is a .... hand job.

Everytime I look up the hood it talks about one sheet of carbon fiber and rolled edges but I haven't seen anything about rain guards.

A lot of dirt gets inside the engine compartment here and even more if I get the TS hood so if I know how to take care of it will help me decide. I'd get the GTR style if I think the TS is too much exposure.

I could be wrong, but I could have sword I remember a thread where the discussion was about how the real hood came with rain guards.

The slits in the TS are like, the opposite direction of rain that would go into into it. It's not like a ram air style that's meant to take in the outside air and cram it into the engine or engine bay.

I would not worry about it that much unless you are driving through a hurricane amount of water/wind.
The only concern you really need to have is over maybe 5 years as electronics get old and wires become exposed to keep them wrapped and where your filters are. Though with most hoods/vents the filters are far away so that is of little concern.

I'll look for the thread about the rain gaurds. Thats good info to look up. Thanks

Thx for the input guys

I have an aftermarket hood....it has scoops....it came with detatchable panels under both of the scoops.....mine also has scoops in the dead center which don't have panels...and I've washed my car by hand on numerous occasions and never had a problem.

And here is the best photo I have of my hood I can show from the images I have in my photo album on this site:

You can see the scoops and the center part of my hood actually dips down and there a dual panel there with no protection behind it.

This is the one i saw off ebay, its amazing!!! Im just a pussy and dont wanna hurt my Z lol

Check your PM's when you get a chance. :tiphat:

It shouldn't really be a problem imo, had numerous of vented hoods on my previous cars and it doesn't seem to have done any damage or rust to be seen with the naked eye. =] but then again that's just my perspective on it.

Where in FL are you located?

The VIS carbon fiber hood I have has this^^^^^^

daytona beach

hows the quality and fit on that VIS bro?

I changed the stock top mount intercooler on my old STi to a front mount and left the scoop alone. When it rained, it filled my engine bay full of water.

Not saying it was a good thing, but I never had any negative affects from that... other than a crazy nasty engine and engine bay.

The scoop always sucked in trash and debris from the road is a downside.

anyone has any picture of this rain drain thing. I just finsih doing a custom superleggara style hood, vents are big so just a bit worried about dust and washing problem. But rain no issue as it doesnt rain here at all

I've got a similar climate minus about 30 degrees. Dry and sandy. Dirt get into the engine compartment without vents on the hood. So add huge holes to the hood will surely allow a lot more dust inside the engine compartment. So it is a concern to how much dirt and washing the engine can take.

Any sponsors selling the seibon TS hood that can get us picture for the drainage system would be great.

Quality is good on the VIS and we chose it over the hotwheels similar hood. For me, it was a functional decision to make sure my engine bay stayed cool after adding the turbos. I wasnt expecting it to look as good as it does.
