gc8 boost solenoid vacuum lines

[That Guy]

I know I really should do a search for this but well, I haven't. 

Can anybody point me in the right direction of where the vacuum lines for the boost solenoid go? I have found 2 of the 3 lines that come out of the center of the inlet manifold going nowhere and the line from the b/s to the throttle body has a tee pipe connected in going nowhere. I think this might be the beginning of my boost cut issues.

Pretty sure its this on my BC5 RS (wouldnt be surprised if the setu is similar on your car)

 

 

if the 2 pipes are round the wrong way it will cause a boost cut, also the solenoid could just be F***ed and causing a cut

 

Id say on your b/s to throttle body pipe with a t-piece in it probably had a boost gauge running from it

alright man, cheers for that. That part is now sorted. 

Any ideas on the three lines from the center of the inlet manifold? what I currently have is drivers side going to b.o.v and a teek pipe to nowhere, center is about 100mm long angry going nowhere, passenger side runs back under the inlet Manny and disappears some where. unable to track it with the manifold in place

Those are all pressure outlets for the intake manifold

 

so all 3 of them are the same I believe -

 

1 - -- to the boost sensor in my drawing above (which is the MAP sensor i believe

1 goes to the BOV

1 goes to the round thing on the left hand side of the radiator behind the headlight

not quite sure what this does but ive seen alot of people remove them, however i never have

 

if you dont have one I would block it off, if its just left dangling there id will leak hard

Thank you very much good sir. I still have a good few evenings work to put in before I'll be able to take for another test drive.
