Replaced my old turboxs blow off valve with a new one from cxracing, my old one had 1 barb n the top but the new one has a barb in the top n side. How do I hook this one up?

 

if it looks like this, use the top one

 

but what does the bottom one do? i had the same exact type s "style" bov on my old setup a few years ago. i used the top port. it worked fine. i actually broke the bottom port off on accident, never knew what it did.

 

Boost controller

 

on the bov? good call

 

Yes it does look like that, thanks for the info guys, so how does the boost controller hook up in relation to this and the wastegate

 

i was joking. its not for a boost controller. its something greddy did to hook to a second source before the throttle body to help with quicker functioning of the bov. its not needed but if its there and could help may as well use it.

since the type s is like a 1st gen dsm bov on steroids, greddy incorporated the 'dodge garage mod' into the design.
the pic i posted is a type s knock off offered by cxracing.
