Aluminum, alumalite, fiberglass, ABS, PVC, MDF, carbon fiber, cardboard, duct tape, expanding foam, lexan, rivets, riv-nuts, weld-nuts, etc. etc.

The important thing is to understand the function and concepts behind the ducting. Then you apply whatever materials you want to use / can afford to achieve it.

I was going to use hood pins but am going to try the stock latch as it is very well installed and constructed. It weighed one half pound more then the stock hood without the rain guards installed and adding anything to the stock hood well probably make up that difference. I really like where the vents are and their design and size, should move lots of air through the rad.
How has this hood held up?did u ever get hood latches?

I wouldn't bother with any of that. Just do whats proven and free:

TSIs are bad, we are trying to get air out of the hood, not in it. You basically want a vent in front of the hood-hump, slightly raised.

Boost93 The hood is still the same as the day it was installed and I am using the stock hood latch with absolutely no issues and it has seen 10 track days this season so far. As far as function is concerned I think it is perfect, the car runs cooler and it has more down force up front. It is a little narrow on the fit so if you are after a perfect fit for a DD it might not be up to par, but my car is strictly a track car so it is exactly what I wanted. As for rain, it comes with rain panels that screw in underneath the vent openings but since I don't drive it on the stree in the rain I don't use them. If it rains at the track I just lay a piece of plastic tarp over the K&N filter on the drivers side when the car is sitting so the rain doesn't get on it, other then that the rain just runs down off of the other areas.

Pretty sure that is too far forward as it is in front of the rad.

I doubt the force behind the radiator is higher than the force on top of the hood there. Might be a worthy experiment.

The lip on that hood outlet should make a big low presure area, is it in the ideal spot, probably not, does it help?, sure should.

According to a a pressure map of the nb hood someone did a while back. The best spots for vents are around the sides near where the overflow bottle is and the other side where the filter is at. Now of course that's kinda far out of the way to route the radiator air to. It gets worse as you get towards the center so technically the best reasonable spots are where the chaser kits have their vents. That way your vent passages don't get in the way of the intake.
