boost control valve - which outlets to use?
dexion7 - 6/10/13 at 10:28 PM

has anyone used this valve and can tell me which holes to use. think its off an audi / VW. the make is Pierburg and it seems to be quite a common one.

i'm hoping to run up to around 15psi and the waste gate spring is 5psi so the idea is to T it into the pipe from turbo out to waste gate actuator.

I don't know which is which with that particular valve, but one will come from the boost/pressure side, somewhere near the butterfly / dumpvalve,into the solenoid, then 2 from the solenoid, one to the wastegate, and the leak off one needs to go back into the suck side between airfilter and the turbo. Thats how they are on sr20det's anyway. Mine ran fine without it for a while anyway just with a pipe from the boost side straight to the wastegate when I was a skint apprenice and it cocked up on my 200sx.

one further question: do you know what frequency these valves like to work at? I'm running mbe and there is an option to pulse the valve at either 10hz or 100hz.
