well its been about 4000 miles since ive installed the turbo on the car...
where to start...well to begin with the car is only boosting 5psi...i thought ok i got a boost leak somewhere....did a boost leak test like this one from this site http://www.vfaq.com/mods/ICtester.html ...checked every coupler for hissing and put soapy water and none are leaking...while doing that i noticed the boost gauge was only going up to 9psi due to the BOV opening up and letting all the pressurerized air out not letting me go past 9psi...
i reconnect everything and do some runs and the car runs at 5psi...i decide to diconnect the actuator and plug up the j-pipe to see if the boost will rise...and it did to 8psi....with the actuator disconnected i should have unlimited boost....im suppose to have a 10psi spring on the BOV so when it reaches that i hear the BOV letting all the air out and back into the system...ive tried 3 different actuators already and they all make me boost at 5psi connected...so i dont think the actuator is the problem...
i also did another test...i connected the boost gauge line to the j-pipe to see how much boost i was generating straight off the turbo and it was the strongest run ive had...actually fealt right...pulled hard...BUT...boost gauge was reading 10 psi right off the turbo...now that makes no sence...NO actuator connected and its reading boost before the BOV realeases the air and only 10psi...idk if im making sense...but i dont think 10psi is correct...i think i might have a bad turbo on my hands but not sure yet...yes the boost gauge is reading correctly and there are no leaks in it...i did a pressure test on the line and it reads fine up to 30+psi with no leaks...
what it comes down to is...why is it that with the actuator connected it boosts only 5psi and with it disconnected only 8 psi...and when boost gause is connected right off the turbo...only 10 psi is detected and no more....
i really wanna fix this...car idles smooth and drives like stock...i dont mind boosting 5 psi for the mean time as i dont race, and i need a car to get me to work and school until the semester is over and i can start working on it again.
any ideas... you can see my set-up and build tread here https://www.thegalantcenter.org/show...=20588&page=19
