Holy Mother of God! I was chastised over this post and 1 1/2 years later the great Jake Raby says the same thing I did about the air being pulled along the short side radius. The Y shape is the most important part of the piece, even according to Jake Raby.

The short side radius of the IPD is where the trick is. You can't develop an intake component using a shop vac. If you do, you'll never see that what you are doing is hurting performance, or doing absolutely nothing!

With a pitot tube inserted in the intake where the splitter is installed in this photo will give zero, or very, very little velocity on the flow bench. Why? Because the air is pulled to the short side radius.

Yes, I have direct experience with this.
