I commissioned someone to run some computer simulations on it for me .
A video of the Pantera aerodynamics in different configurations with explanations will be put on YouTube in the next few weeks.
here are a couple still pictures
obviously, computer simulation are not as precise as a real wind tunnel, but it gives us an idea…

Very cool stuff. Now, if I could just remember what a Reynolds number was!

Easy… when I poke my finger in your eye, how deep does my finger go in / how hard is your eyeball!
He’s gonna explain the whole thing in the video… He knows his stuff

The Reynolds number is a dimensionless quantity (no units), that is the ratio of inertial to viscous (and vicious) forces acting on the fluid!
I think JFB5177 has the compiled Ford Wind Tunnel data!

Haven’t seen those data…
I have the Style Auto article. to large to post, but this link should allow the download of 75mb pdf

This is very very cool!
Thank you so much for sharing
i’ll print it out when I get back home in a week
The Style Auto article is very interesting, thank you jfb05177
If I remember correctly, the Reynolds number is used to characterize a flow, below a certain value the flow is laminar, above it is turbulent.
The video just posted
Very cool video, Roland!
One thing I might mention (that your analyst might be unaware of) though, is that the wing, and sugar scoop spoiler were probably not added due to DeTomaso Inc. Sa. computerized aerodynamic modeling, but because similar excrescences appeared on competing supercars, and people thought they were really cool looking.
In fact the entire design of the car was made that way.
An excellent example of function following (good) form?

I’m sure he doesn’t know the history and development of all cars on the planet lol
But you can check out the other things on YouTube The company did…
I was just amazed that Pantera runs with the best in drag (without the wing)
Thank you Roland. Very interesting. I wonder what it would be like with a stock Pre-L (Narrow) Pantera, since we don't' have fender flares and NO front air dam / spoiler. But again very cool. Larry
Yes, it would be interesting… I don’t think there is a scanned model available.. they probably have to modify this model…
I will ask …
Yes very cool, I enjoyed the video. I also would be curious about how a narrow body would do, but would also like a pre L vs L model. Many have argued that the L model bumper with the opening above the hood is effective in limiting lift at higher speeds.
Although an extremely limited car, I also wonder if the SI' s revised bodywork addressed some of the issues that were noted in the video, particularly with the unique spoiler up at the base of the windshield and revised rear wing.
