I noticed there are two (vacuum) fittings on the Greddy Type S and I am aware that one needs to go to intake manifold, but which one and where does the other fitting go?

I read on here also that connecting BOTH the fittings together will make the BOV respond faster and sound louder / better?

Here is a pic for reference so you can see the two hose fittings I am talkin about on the side of it ...

I believe the top port is your main vac/boost source. The bottom is strictly a boost source for higher boost applications? Anyone please chime in if I'm wrong.

 

Yes its the top port. but do both for faster response.I put a nipple on my intake pipe( between bov and intake) and put the bottom one on it. I just had to take mine apart because my diaphram is busted . hope this helps.

Interesting... because I found this saved on PC hehe :

"My top port is hooked to the vac nipple downstream of the throttle body and the bottom port is hooked to the compressor housing. I would say the volume increases 5-10X when hooking it up like that, at least on my system."

 

humm.. i dont have anything taped to my compressor housing. is that bad? what could i tap there?

would that be a good place to tap for my 2nd vac line on my bov? BUMP!

 

 

Tap into the hotpipe right after the turbo. Stuff in a nipple, seal it and hook up a line to the lower nipple on the bov.

Should work fine.
