Question for vented hood guys
i agree, rain guards add unnecessary weight and inhibit heat loss. fugg it, just lose the whole damn hood. 
there's a reason why they're called rain guards. you rock them when there's rain.

Q: Are you really worried about heat dissipation while it's raining? Leave them on during rain season, take them off the rest of the time. I don't think you'll be "pushing" your car so hard in the rain that you'll need to be concerned about losing heat...

I'm not worried about losing heat, I'm worried about cold water going into a hot engine and on to the internals.
My original question was, is it safe in the rain.

why do you want/need vented hood?
If you have excessive heat that is hampering your performance - then you are going to have to sacrifice and tollerate installing and removing rain guards when needed.
If you have no need for them, it's probably not even worth dealing with it.

*these are why I said I didn't realize rain guards could be so complicated... every time someone mentions something, you seem to be perplexed by the responses or not quite understanding the concept.
Haven't you discussed any of this with the shop you plan to do the work? If they aren't familiar with any of this, then they haven't done a vented hood before... are you sure you want to be the guinea pig?
What are the vents "uses?"
Yes. Your bay will just get dirtier quicker.

I have a Seibon TS hood painted to match my car. Yes your engine bay will get dirtier even with rain guards, because more air/dust in entering the engine bay area. Its not terrible, and doesnt drip on my polished injen intake. The water is on either side of the plenum and engine pretty much anyway.
I think top secret designed the vents to be far enough on each side of the engine because any water dripping directly on the engine while hot cant be good. Any polished items should be clear anyway. Your intake will not suck up any water unless highly submerged contrary to popular belief.
If you get the hood for free, 5 minutes a week wiping down the engine bay to kleep it in show condition is nothing.
However, if you don't want to clean ur engine bay a little more...a hood like this isnt for you. You could have searched, there are about a thread a week on this subject..more and more newbies on this site.

It would, I would go with trays under the vents with drains. Have the vents face rearward. The only time you would worry about the water to any great degree would be when stopped or if you got some snow on them. Either way the trays would take car of this. Just keep the drains open. Another option is to do a hood that vents like cowl induction hoods do for intakes.
