I just recieved a simple ball-and-spring MBC in the mail. With the excitement of enjoying a long awaited performance increase, I also find myself now wondering about my original idea to jack it in directly off the compressor inline with the short stretch of tube leading to the WG (Garrett). I got to thinking, and wondered if maybe it wouldn't be better to use the intake manifold as a boost source, then on to the WG, while just plugging up the outlet from the compressor? I am by no means an expert on turbo systems, but have heard that by using the manifold as your source there may be spikes but there will be less lag (a good thing with the Garrett). Directly off the compressor will yield more lag, no spikes, and possible performance changes relative to ambient Wx changes. Is any of this true for the 1.6TD? Does anyone have experience with both methods of connecting an MBC?
Thanks.
I would like to know aswell as i will be installing a mbc sometime in the near future.....

i cant vote 2x :cry:
i had a garret,and now a kkk
i prefered the garret btw,more overall power :twisted:
With the style of mbc that I use (pressure switch and air solnoid) I always run it from the manifold pressure, as when I run it from the turbo it is too jumpy +/- 5psi, when I run it from the mainfold it is steady +/- < 0.5psi. I have run this on KKK and on the stock Garrett, as well as the GT seires, ect...
i get smooth response from the inlet on my garrett. I can even tell if im pushing out 0.5 psi, and no spiking or jumping, its uber accurate.
So if the compressor port is creating spikes wouldn't it be better to hook the boost line up to the manifold so the wastegate doesn't see these spikes?
