I don't think I'd run a vacuum pump on the street. The power increase is only above 6000 rpm so you would probably never see it on the street. Besides, you would wear the pump out in a few months of driving if it was a daily driver. For the street just use a PCV and call it good.
Thanks Andy, always interesting ! The intake gave me some ideas, soon as I get around and get my little flow bench finished, I may try a little something I saw on ur intake .
