Here is the science behind the velocity stack.

I was going to model my own custom stack based on this article. Still may, but I already had the 6” to 4” stack sitting in my MR2 so I used that one instead.

This issue I see with doing anything larger than about 3” is the rectangular section just doesn’t allow for a large round shape. At this point my 3D part through that section is right at the equivalent of a 3.9” dia pipe.

Here is a graph showing how small increases in pipe diameter have a large effect on square area. So every little bit helps. Also the model I created.

I like what you did and are doing. Please keep us posted. I did similar sims before but didn't take too much time to look at the underlying principle. What inspired me was the Vortech bellmouth, but just for fun frankly as I was already satisfied with the power I was having. Anyway, always glad to see more engineering inventions. Interesting. ^_^

What software are you using for 3D modeling?
