Interior/Exterior Venting the Bonnet - A Unique Design
Awesome job mang! Thanks for taking the time to bring us along on this project. The pictures & descriptions are great. I'm really looking forward to seeing your final product. 
gnat, I am all but convinced you are either made of money, sold your first born, or have a past you are not willing to share - interpol might be watching.
Nice work though. Don't rush the job just to get pictures of the finished product to us.

but you left out one seriously hooked Mini MODder 
. At some point he will likely be carted off but until they drag him away - lets all enjoy the journey he is sharing.
Love ya gnat
Oh Ah Wee...Paint on the other side too
For those worried these louvers were too flat...note how it does follow the contours.
Just think how much cooling we'd get with this iteration

Wow gnat!Really really nice. I love the look of the smoothed and blended scoop.
My hood needs a face lift do to chips and now you have on a mission to make my own similar to yours. I will do the vents a little different.
Hope you don't mind.
Longboard
Mind??? No way...
Go for it...glad I could inspire people...
I'm looking forward to see what others come up with now.
Oh wait...Bryan you need to send me an RMW Adjustable Cam Gear as "payment" for inspiring you

Simply stunning.
Talk about being inspired, would anyone want to try this having the driver's side vents going the opposite direction to give cold air to the intake? Some changes would need to be made, but could it work?

You gotta make HP/TQ gain claims
of course those things did come off of a TR7 so perhaps you lost a few ponies putting those on . Your gonna have to do the string test - tie some 1"-2" strings and then go out on the highway.
Aero testing? Have you learned nothing here at NAM

I'm not selling them so I don't need to make unfounded claims.
Besides, the main goal was bling and to do them better then Sid.

Based on some of the other airflow analysis threads scattered around NAM, it seems as though that area over the bonnet is a low pressure area (Bernoulli's Principle and all). Thus, it ought to work great for gnat's design purposes. Would probably not work so good for pulling air in.

There's a high-pressure area at the base of the windscreen, but the entire top surface of the bonnet forward of that is pretty much a low-pressure area. That's not to say that you can't have a flush-mounted duct on the flat portion of the bonnet that will draw air into the underhood area - it just has to be designed significantly differently (like a NACA duct).
Here's a NACA duct (the little duct amongst the "Mercedes" lettering, NOT the big honking thing with the metal-mesh screen):
