What thread to put this in? Interesting aerodynamics isn't for just the outside:


Just A Car Guy: Dimpling the intake ports has them picking up 8% more flow and and 5% more velocity

After it's 3D printed they could clean up with an extrude-hone.

That duct must dump into a disaster zone if it needs turbulent flow delivered. Dimples are wonderful on golf balls, but if your shape is not rotating, a simple thin ring about 35% back is all you need, and if you have anything much gentler than a round shape, you don't need turbulence to keep the flow attached.
Home-built instrumentation can be tricky, especially if there are expectations. I once built a manometer, and could not get anything close to an accurate reading, even on such a simple device.

If you follow the link:

That's why golf balls are dimpled, and why Nascar outlawed dimpling the hoods, roofs, and trunks of race cars
Porting and polishing is an art. You can't polish everywhere, sometimes roughness is introduced.

This would require 3D modelling and printing to implement. The resolution of the print might require smoothening in specific places.

This looks like a first iteration.

Is it just me or do the brake lights remind anyone of an Accord?

It is the Lincoln Quicksilver Ghia Concept.
The front also resembles an old Mazda RX7 imho.

Yep, or also a Porsche 924, same difference.

Those intake ports might go under Aerodynamic Oddities.

The front more or less represented the style of the times. And considering the most commonly owned auto brand among designers is Porsche, I see more 924.

The Porsche 924 Turbo went on sale in the U.S. in 1980 to critical acclaim.

Quote:
Though aerodynamics was not a major concern in the early Seventies, the 924’s coefficient of drag (Cd) was a claimed 0.36, then among the lowest in the world for production cars.
The 924 was a very influential car, and saved Porsche.

Quote:
In all, the 924 was distinctive and influential. Its nose, for instance, was aped by the Mazda RX-7 of 1978, and the new-for-’84 Chrysler Laser/Dodge Daytona coupes were unabashedly cut from the 924 pattern (as their G-24 project code suggested).
