Only a fool would run one on a street car. A "screen" ain't a filter. Fine grain sand will turn the supercharger and engine into slag. Does a procharger make boost? What is the pressure drop before the wheel? Lastly how hot is the air and does it really matter on a ride with a large intercooler. In all probability your "screen" would add near ZERO HP at the expense of critical wear and even possible wheel failure... but I guess it looks "race".

I should also add (I did design an air intake for a turbo engine that was marketed), that a rather sharp bend before the the wheel can actual break up the votic flow and increase overall wheel flow.... it ain't a bug it is a feature. Long story short many OEM application have sharp bends not because they are fools, the engineers know that pipe flow does not work when you are dealing with a spinning wheel, and think of this as round sink's central drain.
