8-5-3 boost pattern
#1
hey every1
Okay this is my problem. Im getting a 8-5-3 boost pattern. Before i bought the car, i had the turbos looked @ by a local rx-7 guy and he said they checked out okay. Recently i had a Mazduh tech look over the vaccuum lines and he said all were attached. I lose boost right before the transition and it keeps falling off until redline. Any thoughts on whats goin on? My original thoughts were it might be a faulty solenoid because the secondary turbo is not opening up and i dont hear the "whoosh" of either turbo after 4k.
plmk if youve got ne ideas about this.
Thanx,
Zach

a clogged pre-cat can totally negate ur secondary turbo? I thought it would just drop ur top-end boost from 10psi to something like 8 because of backpressure....

Im making 8psi on the primary so it's got plenty to go into transition. I'm thinking it has to be a solenoid and not the piping or couplers because i dont even hear the secondary spooling. BTW, whats the name of the solenoid that opens up the secondary? CRV?
