Intake Manifolds

Done some reading on the post about the new Mafia manifold when they first came out and was reading the Kasse post when he was testing the p51 heads. Has any more testing or results have surfaced? I am on a 101 course to gain all kinds of knowledge. Has there been a cubic in where the Mafia will start to shine vs running a smaller motor. In regards what people have said aboout the weiand tunnel ram I was surprised to see it would hold its own to the victor. Seems that the Mafia tends to hold a little more rpm's than all others. Any thoughts?
