Random Aerodynamic Oddity of the Day Thread

No, like this, https://miv.hr/upload/catalog/produc...b150a1d43e.png but stretched wide and made pretty.
What's an Ecomodder Album? Maybe it won't show up here until I update my software.

Unfortunately, there were no diffusers and ducting to reduce turbulence, as needed for an ideal variable intake.

Thanks. It is still very tedious, but not ridiculous, except I don't think it worked.

It appears to have:

Nice windsplits.

I thought I did that. Anyway, this is progress. I've got an album half-full of oddities for you to browse. I can't recall which I'd wanted to send before, but there were several instances.

AREO CONTENT: There are too many examples to bother posting a picture, but I'm constantly taken aback at the sight of exposed rollover bars on race cars. Some have vast lengths of round tubing taking the air right side-on. The owners don't even bother with a boundary-layer tripper, to reduce wake size the way golf balls do. Even crude, taped-on cardboard fairings would reduce drag by 60%, and a good job in skinned foam would get to 90%.

My rat rod design from the mid-1990s had cantilever airfoils to replace the VW front torsion bar suspension. There would have been flat plate connecting rods [not shown].

The back was a combination of narrowed track, bobbed tail and a virtual rooster tail of hot air out the original rear window area. I [possibly later] learned it would be configured as a Coanda nozzle by adding a visor/mini Kamm-back.

Today I would balance the Kamm-back with a similar shaped splitter in front. That picture was taken with my first digital camera in 1994. Today a Stable Diffusion AI inpainting could up-res it so I could modernize the details. Hmmm....

Why does it remind me so much of this?

I'll call it aerodynamic since it has fenders.

The XR-6
The Concept That Started it All

I remember this well. I even had a slant six once, but it wasn't an aluminum block like this one. The main takeaway at the time was that Triumph disc brakes (and therefore wire wheels) fit a VW front end.



The body was concieved as fiberglass, bankrolled as aluminum by others, then finally handed to George Barris. Who proceeded to slather it in lead, so it must have been steel. OTOH Gene Winfield learned to work in aluminum just to make the fenders.

Overall it's considered the exemplar for it's disc brakes, coilovers and side-draft Webers on a hot rod at that time. Won AMBR, bettered anything Roth could do.
