Okay, I borrowed an image from the classifieds:
I forgot already who the owner was, but if you dont want me using the image just let me know and I'll take it down.
Blowfish, if you look in the square area you will see a ridge down the middle. That is the splitter I was referring to. But if you see one up close, you can tell it does not angle the air flow much if at all and does little more than just split the air flow. And the square area is slightly forward of the middle cylinders so the #5 and #6 cylinders, I believe, probably dont get the air flow that the others do. There is little more, as I mentioned, than vacuum and brute force of the air flow that gets the air into the cylinders.
The easy solution is just to put some type of metal strip in there that would provide a more gradual ramp with perhaps some type of grooves or something to bias the flow to the cylinders. You're not going to be able to fit anything in there like full fledged channels and such.
I would like to have the resources, machine equipment and such to extend the ports to the heads up to the square area. Some tubes as it were extended up to the opening of the LIM so that when the supercharger was bolted on it would be sitting directly onto the the ports to the cylinders. But you would still need some type of splitter in there and I dont know how practical all of that would be.
The outlet of the supercharger is so small in comparison that I think at this point its more practical to just split the air better, angle the split better and put in some bias to each cylinder.
