I think CFD can help a lot and for an aftermarket product I would accept CFD only. I wouldn't expect an aftermarket product to have full wind tunnel testing. I wouldn't say it's equivalent, but it has a lot of value if the CFD analysis is performed by someone who knows what they are doing.
I like the shapes and the idea. I'm not sure about the sharp angle between the base and the bolt-on component (see arrow). I feel like it will provide more downforce and drag, but possibly more of each than needed. I would prefer to see a softer angle for that reason. But if you had someone do a CFD analysis of it - the resulting information might make me change my mind. Whatever I purchase, I want it to function acceptably on track.Been working on this RATTLESNAKE a bit behind the scenes. Lets discuss a little of what you are seeing.
Overall the RATTLESNAKE will have an increased height over OEM. The center "A-Cup" as I have named it will add another layer of aggression to the swing. It is designed to be the same width as the aeordynamic valley that is located on the roofline. Air will naturally flow over the car into it.
The rear profile is about where I want it. At certain angles the front view looked too thick. Going to make some small changes and bring down the height a tad on the edges. Then going to make the "A-Cup" a little taller. Overall the height will decrease, but the lower edges will make the center section more pronounced.
Also incorporated broader coverage on the back of the OEM swing at the outer edges. This will allow for more carbon fiber presence from the rear view.
"OEM plus" is the concept here. It will stand far enough apart from the OEM piece to be noticeable, but no so far different it loses the original level of sexiness the car had. I may do a CFD pull, but the changes here are not so drastic that it should unbalance the car. I would view this as an aesthetic upgrade over a performance modification.
Once those few revisions are done I will share some pics and start with preparations to build the mold and carbon production piece. Let me know if you guys like where this is going
All very good points. The angle of the gurney at the point it bolts to the swing is unchanged from OEM. I had some of your ideas to change the angle, but hesitant on the adjustment as it has already been proven. Plus it affects the hardware too. I’m still noodling it.I think CFD can help a lot and for an aftermarket product I would accept CFD only. I wouldn't expect an aftermarket product to have full wind tunnel testing.

I remember a kit car at my local road course that had a really annoying whistle at speed. If a wing induced some kind of vibration that caused a noise that wouldn't be great, plus it could cause a fatigue failure over time. CFD will help you to understand how thick/strong the parts have to be to hold their shapes under wind load on track. Also it would be nice to have a general idea of how much the change might impact downforce and drag.

If this is an add-on to the Ford factory base, I like that idea as well.
Yeah I’m liking the looks of that!Been working on this RATTLESNAKE a bit behind the scenes. Lets discuss a little of what you are seeing.

Looks good! I'm interested in the Boa Constrictor, you still working on that?
It is on the back burner. Cost to produce it was high. Higher than I think the market would tolerate.
