Thread: MBC pressure source

I am wondering which source would be best for a MBC. From the intake manifold or the compressor housing?

I would think that the compressor housing would be better since its right next to the wastegate and the hose required would be very minimal.

Another good thing about it is that you could then have a clean line to the BOV with nothing interfering with the pressures going to it.

Im having boost spike issues and this got me thinking. Whether or not its related to my spike issue Im still curious.

That is precisely how mine is run and I have had no boost spikes or any other problems :)

Running it from the J pipe or compressor housing gives a lot of people boost spike head aches, it did for me. I run mine from the BOV line even though I don't think it's the best way to go. I'm gonna try running it from one of the unused nipples on my throttle body and see how that goes.

Mine is already teed from the bov line. Its always been that way. Ive been messing with my boost controller all day and I cant get it to stablize above 14 psi. Anything higher then 14 and it spikes to or around 20psi.
