Effectively a cover that snaps on and has a thin strip of rubber that seals down against the hood. The two covers made of carbon fiber and a nice little zip bag to keep them in. PERFECT!

Also, speaking of rain, I would not want the vents too far forward where they could possibly drip rain over air intake or a S/C.

That would only matter if the air intake was a short ram style, and the vents were at the corners of the hood. Drive in a torrential downpour, even with the stock hood, and the underhood area gets wet.

Overall I am not too concerned, but it would be nice to have a quality set of covers. I would actually be more worried about engine wetness when the car is sitting still. For example, the car parked for a few days outdoors (though this would rarely ever happen), but then water is just pouring in.

Covers would of course be an extra optional cost for those that would be willing to buy and use them. That is, if this hood ever actually gets made.

Covers are always a good idea.

What if the hood had a short but wide single s l i t (censored lol) in the hood somewhere behind the roundel so it isn't so in your face and right in the "blue" area of low pressure? The vent doesn't need to be louvered right? It can be small but useful and not destroy the look of the hood.

Lots of great ideas....but

All in question: Material, Shape, Dome/no Dome, Vents/No vents, Location of vents, Size of vents, direction of vents, covers for vents
The permutations are staggering. Any bets this thing ever gets built? Maybe I'm just a pessimist but I am dubious at this point.

Vent covers might be out of the question for most. The more complicated the more $$$. HOWEVER, we were planning on making a back side to the vents that can channel air to a specific place. When doing this we can have run off areas to allow rain/car wash water to drip to a safe spot inside the motor bay.

I have attached a photo of a 4th gen Camaro SS Hood. Underneath it is channeled. It was also designed for rain water from getting into the intake by allowing the rain water to go into a water catch. It work very well with not getting rain water in. The concept is still in use by GM today with the 5th gen Camaro ss.

The water would could be directed to drip onto the undertray in front of the engine.

I had thought of channels under the hood, but the complexity would add so much to the cost, without a whole lot of added benefit (dripping in one place rather than another). I'm not sure if there is room either, but a cool idea none the less.

YES WE KNOW ITS NOT LATCHED! Im not sure why it wasn't. Anyways Brandon's hood sinks down about 2" toward the front and it has no clearance issues. Plus his intake system is pretty custom and is almost identical to yours but its just on one side.

That's about the best design I've seen yet in terms of getting rid of heat. Not so much for an intake though.
