Lets ask this here too.
I have had this twinturbo setup for almost a year know.
but I havent used it ...
I was thinking, that I will put it to my "every day" car ( 156 sportwagon q4 )
The manifold goes easily, exhaust can be done, problem might be the control... ?
Vacuum controls the flow between the small and large turbo; well I could use the normal
vacuum control there, right... ? so when the boost is right, it will open more and more the
flow to the large, same as opening the vnt as standard....
the large turbo itself has another vacuum control .
and those ttid ecus has 2 controls for the boost, I only have 1 .
Could the large turbo control problem be solved, just by changing the vacuum control
to an normal pressure control, and put there like 1.2 -1.3 bar pressure clock to control it.
After that the normal wastegate opens and boost is that ...
I think it should work nicely, but what you guys think ?
