I checked logs I have when running at the track, and I see around -11.4 PSI (which is around -22.8 inHg) when I let off.
Also, looking at the pics of your intake setup, it looks like you aren't shutting off the air intake on the passengers side. With the T-fitting you have, wouldn't some of the compressed air from the turbo get pushed into the passenger side air intake pipe?
i see what you mean but it has to be in psi it wouldnt make sense the other way around in inHG i mean. that would mean i am makeing less boost at wot then without the turbo. and i can tell from when im just driveing around b4 the turbo kicks in and after that the turbo is pushing harder then the sc. ill see if i can get more data for you guys next run.
if you look down near the front left of the engine bay i have put a oneway valve to open when the sc is sucking and close once the turbo catches up
