The general consensus seems to be that the stock intake is pretty good. Do you need something smaller than that?
i used a vacuum cap secured with a zip tie to plug the vacuum pump inlet. i've been racing it like this for a full season with no issues. a mechanical vacuum pump on a boosted engine is a great innovation, but venting it to the valve cover, not so much.for those of you doing a crate motor using the ford performance control pack, if you don’t need vacuum for a power booster or other vacuum accessory.....you’ll have to remove the cam driven vac pump since leaving the suction port open will simply pressurize the crankcase.
Could you please post a photo of the PCV connection?So, Ford tech sent a cooling flow diagram, our concern was item 11 and thanks to “Ecoboost”, one more connection was made. Ford tech also confirmed the PCV connection on the engine side of the throttle body but not the engine connection which we suspect is that rear connection. Also our pressure regulator sensing port on the intake was confirmed. Getting ready to pull plugs and rotate for oil pressure check.....yes!!!
