It seems to me that a tunnel ram, down stream form a centrifical (or any other type of) blower wold be counter productive. A "tunnel" ram's purpose is to create enhanced flow thru the extended runners at specific rpm ranges. Your blower is providing the flow; so what is the tunnel ram's function? The fast cars are running a single plane manifold with their centrifical blowers or turbos. It's hard to argue with success.
I know, I have posed the question several time wether or not it will work. And you just dont see it being done.

In reality, I will probably never have a power adder car. The next mill I do will probably be a big incher out of a dart block. An all N/A.
I slso wondered if the larger plenum on a tunnel ram is harfer to pressurise, and you would have to run the blower faster to get the same positive pressure. I have asked this question to several builders, and never got a reply. That orange nova that Pro Charger built with the bbc 427 inch motor has a dual carb setup, but it's on older offenhauser low rise, with two modified holley 450's.
