ProFec B 2 on s13 redtop

[2fast4y0u]

i need to know how to hook this thing up. i followed the instructions correctly but cant boost over 7 psi. i am wanting to know what vacuum lines go were and what inlet/outlet do you have them plugs into on the boost selinoid.


right now, as per directions - i have the inlet labled COM hooked to my wastegate acuator. i have the inlet labled NO ran to the brand new nipple on my charge pipe. i have the vacuum line hooked to the intake manifold as per directions as well with a T off of the fpr.

now here is another thing. i am running a hks SSQV that is welded to the charge pipe. there is a vacuum sorce on the back of it. if i have the hooked to the TB or not hooked the TB the BOV still works.
Im so confused.
any help please

You have it hooked up properly. Did you take the plug out of the NC port? If not, do so.

Also, your BOV will work without having the vacuum source connected. It will just leak. The vacuum source helps to keep the BOV closed while boosting.
