Question... I just hooked up the Hondata boost solenoid in my 94 Ex yesterday. Running a Tial external wastegate I've got the top side hooked to COM and the boost/vacuum source hooked to NC of the solenoid, leaving the normally open to vent. (Wanted it hooked this way just in case of a failure I'd still be running off the WG spring) And the bottom side hooked to the boost/vacuum source like normal. Yet now when I start the car, there is a decently strong vacuum coming from my NO side of the valve which would mean its coming from the top side of my WG. Is this commonly what happens and that's why they usually put the muffler there? Or I was thinking maybe I'm leaking air through my diaphragm in the WG. Wanted to get a second opinion before I went tearing into the wastegate. Thanks

should not have vacuum on the side port of the gate. if there isnt a port on the compressor housing for the pressure source, we drill and tap and make one.

 

I have it hooked into a vacuum block now, you recomend I move it to the compressor housing? Maybe a dumb question, but wouldn't there be vacuum there as well when not under boost?
