I have some experience in designing and building supercharger kits(we designed and built the blower systems for Stillen on the Maxima)-here are a few tips. The belt alignment has to be perfect in every axis or you will throw belts. The blower can blow through the MAF,but it will be much better to draw through the MAF and the throttle body should be mounted in front of the supercharger, not on the manifold in stock configuration. You can run without a bypass valve by air temps will go up significantly under cruise conditions and will use more fuel this way (increased parasitic loses). I doubt the stock MAF will be able to cope with additional airflow from blower, but might work at lower boost levels-we have had good luck in NA applications up to 123 wheel hp so far. Blower needs to be rigidly mounted using mounting plate to engine to keep belt alignment true-this takes some design work. It is a good idea to have blower blow through stock intake as this will help ower compared to blitz set up with short runners. This is not something that can be thrown together, but it can work.
