I don't think it does, I think it runs like a normal compressor but the ducting/casing is pretty trick. I've worked it out from a few pictures and I think it also explains the twin air filters and feeds to the compressor. Just need to find a few minutes to annotate some pictures and do a quick CAD model. Will add details to the Engine Formula thread when I get a chance.
