According to the autosportracetech site's test for the CRV and , the port(B) that sees pressure should be able hold 15psi. In the search for the cause of lack of secondary boost I have had the opportunity to test three seperate CRV's. All popped at 6-7psi. Is it really posible that all three are bad? Any body ever done this test and measured 15psi? I'm in the midst of troubleshooting poor(2-3psi) boost at transition. So far I've found a bad check valve and bad turbo controll solenoid. However, no change in boost pattern after replacement of defective parts. I'm trying to rule out the CRV at this point. Any input would be appreciated.

Have you checked the specification in the FSM? I vaguely remember seeing a test there; it may be different.

15psi sounds correct, considering that both CRV's need to be able to handle 12 psi in stock form without venting. There's a good possibility that the valves you had were bad - have you had the opportunity to test a new one yet?

Did a search and came to the conclusion that my CRV is o.k. Shop manual test is simpler than autosportracetech. Just apply vac. to port A to verify flow from port B to C. I found a thread asking the same question and most of the replies seemed to disagree with the 15psi figure. On a lighter note I think I may have found a very important contributor to my secondary problem. The two 14mm bolts on the turbo precontroll actuator bracket were backed out quite a bit. It would seem that under this circumstance the precontroll valve would never fully open or close since the actuator housing wasn't secure and immobile. Thanks for your response, broken93. I'll post my findings.

My boost problems are finally solved. After tightening the bolts to the turbo precontroll actuator my primary boost was right back where it was supposed to be. Previously it was putting out 8-9psi.
I still had the problem with very low secondary boost(<3psi). After staring at the colored vac hose diagram long enough I began to suspect the charge relief solenoid.
Long story short, I had accidentally switched the lines coming off the back(passenger side) of the charge relief and charge controll solenoids when doing vac hose job. Now the car pulls like a muthah futhah! Before I put the reman in boost was 10-5-5. For the first time I am experiencing what a propper pattern is like. Crazy, man.
I must express my thanks to autosportracetech, the Forum, and to the all- mighty colored vacuum hose diagram. These three sources provided all the answers to my questions. I am now one with my FD.... For now.

Good work, and have fun.
