KD93R1 Posted November 10, 2010 Report Share Posted November 10, 2010 Just wondering if anyone has experienced a wastegate that just sticks open? I was driving, accelerating normal when I noticed the car seemed a little louder exhaust wise. Then I noticed I seemed to have stopped building boost. Pulled in the garage, checked vacum lines etc. and all seemed ok. I could hear an obvious exhaust leak around the exhaust manifold. I put my hand in front of the wastegate out port and it was open no doubt about it. I came inside and had dinner. Went back out, started the car and it seems to have closed and sounds normal. I took a closer look inside and it is pretty black, carbon build up I assume. Guess I should clean her out. Is this normal w/a wastegate?

Patterson Posted November 10, 2010 Report Share Posted November 10, 2010 Bad actuator possibly? What kind of turbo is it? Quote Link to comment Share on other sites More sharing options...
KD93R1 Posted November 10, 2010 Author Report Share Posted November 10, 2010 Turbo is GT35R. Wastegate is Synapse 50mm. I drove the car today, seemed fine except I didnt get on it at all, but the wastegate is shut. I was wondering if my AEM Truboost controller can hold it open? Oh yeah, turbo and wastegate have 2k miles on em, maybe. I think the boost controller was holding it open or it just stuck from debris. However, since I never experienced this before, I could easily be wrong. Want it to be right though, hittin the dyno Friday. Quote Link to comment Share on other sites More sharing options...
