Keith, I wasn't saying these things because I like to type. The reason I took the time to share my experiences is to show that there are benefits to using even partial bank separation, and the benefits increase the closer you get to complete separation. This helps in understanding fully the benefits of a true split scroll system. These are results that I have witnessed in the evolution of my header system. Below is a picture of my Generation 1 flange. You will note it does not have a split volute. With that change alone I saw a difference in both how the engine ran and sounded indicating increasing efficiency.
The things Kenik is talking about take this evolution to the extreme, and you see increases in performance with each step.
