so i have the recirculation fitting on my hks bov that goes to me intake. now my question is with my previous bov which was a blitz dd. i had the vaccum signal come from the intake manifold. do i still hook up the vaccum line to the bov ffom the intake manifold? if so where? does it go to that lil shaft on the end?

 

I don't understand what you're trying to say perfectly, but BOVs usually have a small "nipple" you put a vacuum line from the intake manifold.

The reason for this is that the pressure difference between the intake manifold and the piping is what opens the bov valve.

 

yeah sorry it was a dumb question.
