BOV , 2 ports question.

so im temporarily using a CX racing greddy knockoff bov, recirculated.

what is the bottom port used for? I heard you connect it to a boost source or something, is it okay if I plug it?

I noticed air can be sucked or blown through that small port. I tested it by blowing air into the recirculation hose, and air came out through the bottom port, also when you suck air , air will be sucked through that bottom port.

since the recirculation is on the intake, I think unmetered air is being sucked through that small port. Ive been having some boost hesitation at a certain throttle around 3800 rpmish. but once you step harder on the throttle the problem goes away.

so I plugged my recirc and let the bov run vta, problem disappeared. So ima assume it has something to do with that port. if I plug it will it cause any problems? or just tap into one of the charge pipes and/or t off the wg source?

thanks and let me know


(note, I already boost tested my system at 10psi, bov is not leaking. stock sr20det t25 redtop 7psi)

Leave it unplugged, or hook to the wastegate line.

Leave it unplugged, or hook to the wastegate line.

when its unplugged, it seems like air is being sucked through it, maybe cus its a knock off,

cool i guess ill tap another direct boost source

My Greddy RS has two ports like the knockoffs and the bottom one is unplugged.
