Thanks for the diagram but that routing will not work for my EBC. The solenoid on the EBC must go between the pressure source and the waste gates. That diagram will only work with a bleeder style MBC as well (ball and spring type valves must go between the boost source and WG's just as the electronic ones do). I did also think about the possibility of the turbo seizing on the side that feeds the solenoid. My thought is that on a setup with both throttle pipes feeding a "T" if one turbo fails the EBC solenoid may still not get enough pressure to actuate the waste gates. I figure that the boost pressure from the functional side will just bleed off into the side with the seized turbo too fast for pressure to build in the hoses to control the WG's. My main question is if there is any other reason that people run both sides to the solenoid. Along the same line, does it really make much difference in response time if the lines to the WG's are not the same length? I have installed a few MegaSquirt stand alones that ran a map sensor built into the ECU. The designers of the MS system ran lots of testing to determine the lag, if any, in response on the map due to long runs of vacuum hose. They claimed next to no difference in response time with longer runs of hose vs shorter ones. It just got me thinking that if the hoses of the EBC solenoid and WG's didn't have to be the same length then the hose routing could be made much cleaner...
