9" Air Filter Drop Base - How Much Interest?

[YerDugliness]

Thanks--the "swirl coefficient" would, I assume, reflect the buffeting effect from the air stream having to make the transition from horizontal to vertical. If that is so, I would assume that the "X-Stream" filter tops we have been discussing here, which in effect have filtration material on the top of the air cleaner, would offer reduced buffeting since they would already be presenting airflow in a downward/vertical direction.

While not exactly the same as I used on my GTO, here's a Mr. Gasket product that does look similar:

I see the "glass-fiber" filters flowed best, but obviously they would be a poor choice for a high-mileage street engine. NASCAR engines are rebuilt after each race, so if any fiberglass should find its way into the cylinders, it would not present that much of a problem.

Great article, thanks!

OK guys, here's where I am with the project.
I am including "before" and "after" pics. I had a metal spinner do the tooling for a 9" flat base, out of .050" aluminum material. The pics are my prototype, so it's a little rough.
As you can see, the base is FLAT with a turned-up outside edge and 5-1/8" center hole. The next challenge was the outside edges hitting the float adjusters. I made a small round notch on each side and it dropped right on!!
It still sits on the carb lip, so it doesn't touch any parts of the carb. I don't think the air filter is compromised at all by the small notches.
I believe that this is the absolute lowest baseplate available for a 4150 carb!!
I have now been able to triple the filter area previously being used (with an x-treme top), without cutting into the hood for side clearance. It all fits under the bottom of the hood profile. If I clearance my hood scoop opening a mere 1/2" on the sides, I could go even taller!!

The .050" material could be anodized as well.

So, how much interest out there?? I have the tooling done and can pop some out if there is enough demand. I still have to figure out my costs, but I'm not trying to make a killing. I'm just glad I solved my problem!!

Any feedback, suggestions etc are most welcome.

Thanks!

Sorry to follow up on my own post, but maxxed out on pics.
Here is a pic of the plate sitting on the carb...
