Concern Making Custom Hood Vents, Routing the Rain Water? Options

[mgnt232]

Ok so doing some research and need some help with this.
Im looking to make one of two supra hood for my orange celica. I will add the pics at the bottom of both. Keep in mind im pretty set on one of these hoods, there is no reason to bash on the style or have negative comments.

1) The first hood doesnt look like it has any sort of draining system, maybe because the vents are fairly far forward on the hood, and most of the water would fall in front of the engine itself. But I still feel like if i made this, I would want to add in some sort of duct system for re-routing the water.

2) The second hood is much different and looks like it will need some sort of drainage system built underneath. Im curious if anyone here has done anything close to this?

3) Also I know the GT-4 hood has a vent, how do they address the water issue?


Thanks everyone, just looking for some ideas. I want to move forward with this idea. Also the supra hood I assume is much wider than the celica so thats not an option (the front bumper from the supra I cut like 6" out of the middle to make it fit)

First Hood







Second hood





I think this picture the vents are much larger than the other pictures, I dont plan to make them quite that open

Ok I moved so havent been able to get online.
I have a 3s in the car im going to do the hood on. I was really only worried about water ending up on the hot turbo (i can only assume that is bad lol)
As far as the "performance" based tip you were giving, I wasnt real concerned about that, just ascetically pleasing to me lol.
Most likely going for the first one.
I will try to figure out a draining system too.
And as its going to be my daily and I dont have access to a garage Im just worried about down pours when its parked and the speed limit on base is 20mph. As well as it will be parked for 9 months while I'm in the sandbox so I dont want it just getting rusted all out.
How much water isnt caught by the gt4 hood system?

I'd just model something similar to the GT-Four, maybe add some vents off to the side out of the way of anything that could be hurt by water. Yeah, cold water on a hot turbo housing couldn't be a good match.
