Andy-No-Knee Posted June 6, 2006 Share Posted June 6, 2006 I posted up some time ago that I was having some 'issues' with my HKS 50mm waste gate. They are..... It will not hold boost over .85bar, but will open fully when the boost controller tells it to at 1.4bar. So I have tried various things, re-routed the actuator pipework and renewed it - Fine Put jubillie clamps in the ends of the pipework - fine all to no avail. So what I want to do next is replace the brass screw in nipples that connect the pipes to the waste gate, in case this is not a seal and it is leaking from there. The problem is, where from? Any suggestions? Any traders have some I can by?? (Due to the location of the w/g I need either 1 elbow joint that I can tighten up the thread and still control the location on the angle or 2 x stright thread-nipple conectors.) Also, I remember reading on here somewhere where people were talking about the large centre bolt, and that it is suposed to do something inside the w/g. Can some knowegdeable person please remind me what thay was, as I think the large centre bolt is missing and I need to know if I need to replace it. Ta very muchly!

Guest Terry S Posted June 6, 2006 Share Posted June 6, 2006 Carlos #1 are you sure it is seating properly #2 it may have the 0.8 bar spring in it are you saying it will not raise boost even when the boost controller is bleeding boost off. Maybe worth popping into Phoenix to have it checked mate. Link to comment Share on other sites More sharing options...
Andy-No-Knee Posted June 6, 2006 Author Share Posted June 6, 2006 I think it has the .8 spring in, but I want it to stay shut until I want it opend, which is how the AVCR was programmed to do it, but it just wont hold it closed. I was kinda hoping to keep costs down and do it myself, as I am but a poor fireman and cant afford to eat! Link to comment Share on other sites More sharing options...
Guest Terry S Posted June 6, 2006 Share Posted June 6, 2006 Carlos its kinda not making sense bud unless the AVCR stops the WG seeing any boost at all like a turbo smart can, but otherwise it will always slowly open. Can you MSN me so I can talk you through it? Link to comment Share on other sites More sharing options...
Wez Posted June 6, 2006 Share Posted June 6, 2006 Are you trying to hold it closed to improve the spool/lag of the turbo? Link to comment Share on other sites More sharing options...
Andy-No-Knee Posted June 6, 2006 Author Share Posted June 6, 2006 Well it is suposed to stay closed until the boost presure reaches the pre set level in the boost controller and then it opens to allow the extra to blead off, but it isnt even doing that! It pulls like a train up to .89 bar then when it opens it slows right down but continues to rise to 1.4bar. Had a chat with Terry and going to try what he suggested......

Alex Posted June 6, 2006 Share Posted June 6, 2006 Sounds like the boost controller isn't up to much....but I could be wrong. Link to comment Share on other sites More sharing options...
Andy-No-Knee Posted June 6, 2006 Author Share Posted June 6, 2006 Its an AVCR, and I'm not 100% sure, which is why I'm hunting down all the other psoibilties before I spend out getting a new one. Also, there is the question of the centre bolt, which I seem to recal someone saying affected how the power was delivered, eg the severity of the w/g opening???? Again, not 100% on it so I'm askin.... Link to comment Share on other sites More sharing options...
Wez Posted June 6, 2006 Share Posted June 6, 2006 The center nut just adjusts the tension on the spring as the spring will be rated over a small range, ie 0.8 - 1.4 or 0.5 - 1.0 bar. I have mine wound all the way in/out to give me 1bar, you then use boost control to increase it. Link to comment Share on other sites More sharing options...
