i need to take vacuum for: boost gauge, BOV, Map, boost controller but i seem to have run oput of vacuum nipples on the intake mani.

what can go together on the same line or in other words, what can share a vacuum nipple?
or does anybody have any other suggestions?

everything iirc they all share it anyway on the inlet manifold...can't see it making a difference

ive been told to make sure the map and the boost controller are seperate

odd..if they were on different nipples next to each other on the manifold they would share the same pressure..but i guess ifs theres a reason i can't see...

can't see an issue myself..easy then share the bov and boost gauge

i see your point maxi

what do you think of using the nipple where the oe FPR gets his vacuum for the boost controller anf share BOV, FPR and Boost gauge?

will every component get the right amount of pressure?>

MAP sensor needs its own un-intereupted vac line, I also like to do the same to the FPR. everything else should be ok to share. Boost controller will work better with a pre-butterfly (non vacuum) boost feed

i run map and fuel pressure reg off their standard nipples, the bov and boost gauge run off a share feed off the inlet and the boost controller/actuator runs off a feed directly on the turbo housing itself

@ coops
that is how i would run mine but i have a electronic Boost controller that needs one feed from the turbo, one from the aquator and one from the intake.

i will see how i can sort it all out. will let ya'll know

cheers

im just leaving the wastegate at 8 psi cos ive only got a low boost chip any way lol

8 psi should be good 4 now mate, i think imma stick to 10 psi for now even though i'm getting a 1.5 bar map from henk. start with less boost and work my way up :twisted:

i have an electronic boost controller too..........the one for intake can be left vented or else put a nipple on your air filter but it makes no odds atall
