What's your theory behind your placement of the air intake and filter? It doesn't appear to line up with any vents in the hood, but looks to be relatively sealed to it.

Neat work, by the way.

 

I fit the vent out of a C7 Corvette into my hood, which is the exit for the radiator ducting in my car.

Radiator entry is through the grille, with the radiator leaning on a fairly steep forward angle and ducting exits the hood.

The oil coolers are mounted on angles under neath and use the center lower opening in the bumper and vent into the wheel wells/brake ducts, as I have a triple heat exchanger setup for the water/air intercoolers and the outboard coolers are in the old oil cooler locations

 

Thanks!

The air filter was moved there mostly to just get it out of the way. There is about a 6cm gap between the filter box and the underside of the hood, and the plan is to run a duct from the upper passenger side vent (it's forward facing as an inlet), I just haven't gotten around to it (and there's enough airflow that there hasn't been any real change in IATs with that placement).
