Default Advice on how to craft a functional/aerodynamic scoop delete

Since I have a FMIC I have decided to get rid of the drag-creating scoop that no longer functions on my vehicle. I have considered a few options:

1) KS-tech mesh delete and Louvre plate

2) WRB stock hood

3) Keeping stock scoop and installing Oil Cooler

4) Custom hood scoop delete which will serve one of two purposes:
a) Aesthetic delete + allows heat to escape
b) Aesthetic and diverts some air to an oil cooler (jury out on the oil cooler as well)

Of course the easiest option is 3, the second best option is 1, but I would prefer to figure out to craft the most functional and aerodynamic scoop delete. I think the stock hood is a bad option, as the scoop creates drag. the impreza base model hood does not allow heat to escape the turbo area. the KS tech is not only expensive but also out of stock.

I have a local guy who will be able to craft something from scratch out of CF and other materials. I would greatly appreciate some help in figuring out how to fabricate a custom delete.

My vote is to use the scoop as an air intake.

In all honesty, these car's are not very aerodynamic.

Haha I had thought reverse scoops are bad news

As far as aerodynamics, yeah its a GD so the aero is bad to begin with, but might as well improve where we can. The two tracks the car will be at are higher average speeds so every bit helps.

Not sure I follow the 'reverse scoops' bit. I think with some ducting a reverse scoop could be quite effective.

If you don't find another use for the hood scoop a flat plate to delete it is not a bad route. If you can match it to the hood contours, all the better.

Was thinking about crafting a mesh/vented scoop delete that would duct the air into an oil cooler, possibly. I will run the CAI through the passenger side fog bezel in the summer most likely.

Checked out your thread, glad to see the GC is holding up in snow and rain with that scoop intake! Nice!
