What more do you want? Do you want to debate about something? I just disagree with the fact that the rpm and, AG are different animals. Like I'm comparing apples and oranges and, I don't think I am. I believe that the only difference between the 2 is the air gap itself. If it wasn't for that they would be identical manifolds. Is this what you wanted? I mean, I don't understand what your looking for in an answer. I plain and, simple disagree with what you said, that's it nothing more, nothing less.
