775 hp - 470 with 270 heads

I wonder how much HP the vacuum pump adds? 25-40? Is this a streetable item?

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.
