MBC on a turbonetics kit
my friend has a turbo netics kit and im trying to install his MBC for him but i can't find anywere on here... i see there is a spot for a fitting on the top of his WG but were do i run the vac line to the TB vac line?

mbc's are just bleed valves that trick a WG spring into thinking it's only seeing it's rating at a higher level. With no spring, ur basicly running no wastegate even with an MBC

Are you running it inline with the vac source, throttle body most likely, or are you running it where the vac line to the WG goes? Which is best?
I source my vac at the TB and I have a vac block. I have my MBC coming from the vac block to the WG.
So mine goes
(source) TB ---> VAC BLOCK ---> F/IC
.......................................---> Boost Gauge
.......................................---> MBC ---> WG
.......................................---> BOV

ok.. so ur saying u plug in the mbc and it goes from say 8 or 9 psi all the way to 14 correct!
Same thing i had happen..
its the fact that the mbc has such a small opening for air to flow through its restricting a little bit of air going to the wastegate.. and also sometimes the mbc accually will have a ball and spring inside it to create a spike in lower boost range...
what mbc is it?
