if the raised top was somehow curved on top instead of a 90 degree angle like the stock downtube into the driver's side cat, i bet it would make a positive difference in flow (easier on the supercharger). try placing an electric fan blowing against the wall and you will notice the rpm's go down slightly because of backpressure (adding load), the same things happening with the SC top. the supercharger will be easier to turn freeing up some power if the top was progressively curved.
the big question here is would it fit under the hood-
