Thirdgen TA wind tunnel simulation
So there is this website, flowillustrator.com
Won't guarantee any accuracy with it, but it was fun to plug the TA silhouette into the website and get the flow illustration back.
Basic instructions are to get a silhouette of the car or object in question, as close to black and white as possible. Upload the image.

Re: Thirdgen TA wind tunnel simulation
It's good, much cleaner airflow than the Porsche also tested.
To be accurate though, the analysis needs 3D modelling, not just a single side view.
Still very interesting though.
One of the worst cards for aerodynamic drag is an E-Type Jaguar. The wing shape of the E-Type has a lot of unnecessary induced drag.

Re: Thirdgen TA wind tunnel simulation
The Thirdgen itself is still actually very aerodynamic in terms of Coefficient of Drag compared as well as in terms of lift generated.
The 85-90 TransAm ground effects produces real downforce at speed. That said, engineers and designers have learned a ton in the intervening decades.
Yeah the tool isn't really meant for designing or investigating changes to a shape. Its more of a educational tool to show how fluid dynamics works in the most basic sense.
That said, its probably more advanced than the programs used to actually model the 3rd gen back when it was being designed, if they had computer modeling in the design process at all. The thirdgen was designed in the very, very late 70's and very early 80's. And the designs were tested in a wind tunnel.
The software they would have had access to would have been very rudimentary, and would have necessitated a ton of actual wind tunnel work to verify the models.
I did have one generated that had the 85-90 TA spoiler on it, just forgot to upload it. I also generated a few at higher simulated speeds of 60 and 120mph.
