SXY_33 Posted June 2, 2009 Share Posted June 2, 2009 Hey guys i just finished putting in my hypergear hi-flowed turbo and took it for a spin, but its boosting like crazy, my boost gauge showed that it was hitting round 20psi??? ive got a 14psi actuator and my bleed valve is still set on 12psi from the stock turbo. and even tho its boosting doesnt seem to hav that much power???? any help is help my mods: fmic safc 2 (tuned to 12psi, which is wat i was running on the stock turbo) turbo back exhaust, no cat pod filter 040 pump Link to comment https://www.sau.com.au/forums/topic/272918-overboosting-problem-plzz-help/ Share on other sites More sharing options...
217/r33 Posted June 2, 2009 Share Posted June 2, 2009 remove your bleed valve and see if its still doing it. should hold 14psi, you would need to re-adjust it to suit new actuator and turbo. -alex Link to comment https://www.sau.com.au/forums/topic/272918-overboosting-problem-plzz-help/#findComment-4632401 Share on other sites More sharing options...
hypergear Posted June 2, 2009 Share Posted June 2, 2009 If bleed valve is set to run 12psi on a 7psi actuator then on a 14psi actuator it will be getting 24psi. Remove the bleed valve and try again. If there is still a issue give us a call. Link to comment https://www.sau.com.au/forums/topic/272918-overboosting-problem-plzz-help/#findComment-4632430 Share on other sites More sharing options...

RipNGrip Posted June 2, 2009 Share Posted June 2, 2009 (edited) I had a over boosting problem here are some possible issues that could be causing the over boost 1. excessive back pressure causing partial closure of wastegate 2. failing actuator attached to interval/external wastegate 3. failing manual boost bleed valve I had a leaking bov (prior owner had two atmo and plump back) with a creeeeeeping manual boost controller ($22 boost controller on ebay). It was fun...... awesome drive at 17 psi until the AFM maxss out Edited June 2, 2009 by RipNGrip Link to comment https://www.sau.com.au/forums/topic/272918-overboosting-problem-plzz-help/#findComment-4632483 Share on other sites More sharing options...
SXY_33 Posted June 2, 2009 Author Share Posted June 2, 2009 opk so i pulled out the bleed valve and put on the stock t-piece, but it hasnt changed anything, still boosts like crazy, it starts peaking at 3500 - 4000rpm, and nothing has change from my stock setup, just the hi-flowed turbo... and sure its boosting, but no power is comin from that boost!!!! any easy way of checking if the wastegate is actually opening??? could it be my safc 2, maybe the mixtures need to b changed to suit 14psi??? would an ebc fix this problem????

Moodles2 Posted June 2, 2009 Share Posted June 2, 2009 Sounds like a (vacuum related) hose has come off and your getting unlimited boost Link to comment https://www.sau.com.au/forums/topic/272918-overboosting-problem-plzz-help/#findComment-4632962 Share on other sites More sharing options...
Ultimategtr Posted June 2, 2009 Share Posted June 2, 2009 Def a case of unlimited boost... check t-piece again.. post pic if possible..or by far shot.. the actuators stuck closed.

ashneel Posted June 3, 2009 Share Posted June 3, 2009 i had similar problem with my highflow. acuators set of 15psi car was bosting close to 25psi with a turbo smart bleed valve once that was removed boost went down to 15psi. while overboosting i didnt notice any extra kick to what im getting with my current 15psi Link to comment https://www.sau.com.au/forums/topic/272918-overboosting-problem-plzz-help/#findComment-4633254 Share on other sites More sharing options...
SXY_33 Posted June 3, 2009 Author Share Posted June 3, 2009 (edited) yeah i removed the bleed valve... here is a pic i also tried changing the "yellow" and "blue" hoses, but nothing seemed to changed is it correct atm????? what else should i check, which is the vacuum hose???

hypergear Posted June 3, 2009 Share Posted June 3, 2009 Remove the pipe from the solenoid and plug it straight into the actuator. Ie. 1x pressure source from inlet manifold straight to actuator. Do not plug into factory solenoid. Link to comment https://www.sau.com.au/forums/topic/272918-overboosting-problem-plzz-help/#findComment-4633502 Share on other sites More sharing options...
R31Nismoid Posted June 3, 2009 Share Posted June 3, 2009 If bleed valve is set to run 12psi on a 7psi actuator then on a 14psi actuator it will be getting 24psi. Remove the bleed valve and try again. If there is still a issue give us a call. How does that work? You put a bleed valve on, set it @ 15psi (using a 7psi acutator) and then put a 14psi actuator in - its still going to be 15psi. There is no magical increase to 22psi because you changed actuator. I changed my ext gate from 7psi to 14psi, overall boost didnt change (was running 17psi) Link to comment https://www.sau.com.au/forums/topic/272918-overboosting-problem-plzz-help/#findComment-4633543 Share on other sites More sharing options...

Do not plug into factory solenoid. so ur saying that i plug the hose going from the inlet pipe (the one the pod filter is on) straight into the actuator???? and wat just block the one from the intercooler pipe or do i still use the t-piece and connect it to the intercooler pipe, just avoid the standard solenoid???

SXY_33 Posted June 3, 2009 Author Share Posted June 3, 2009 another quick question... i hav a safc2 which i used to tune the ratios for the stock turbo at 12psi. now that i hav the hi-flow and 14psi, should i get it retuned, do my ratios need changing??? or should it still be fine?? thanks again guys Link to comment https://www.sau.com.au/forums/topic/272918-overboosting-problem-plzz-help/#findComment-4633629 Share on other sites More sharing options...
