The opening sketch is very interesting.

Would it operate at the aero-template profile in cross-section or be better suited to operating in free air and larger than the envelope?

One major concern would be corrosive effects of automobile exhaust on the materials.

With that much mass/surface area I can see this being all titanium although perhaps there are some high temperature plastics that are carbon based that I don't know about.

The FW-190 video was amazing, even though I only watched the first half before many of the heavy charts came out.

It touched on "ram-air" intake only being effective on automobiles +80mph, first time I've heard that claim.

The air-intake being post fan and internal begs the question of why Porsche didn't do this on the air-cooled 911 models. Seems like an easy way to semi-supercharger/blower one's engine if there is already a powerful fan running.

On the older 911's like my car (1977), it would be pretty easy to cut a hole or slot into the cooling fans fiberglass ducting shroud and close loop it to the CIS airbox located just above it.
