and1c Posted July 1, 2016 Share Posted July 1, 2016 (edited) So, after more fettling took the Supe back for it's retest today, on the way there it wasn't boosting at all. When I got there I found an intercooler pipe had blown off post intercooler which was from when I removed it to replace power steering pump.... Whoops. So I sorted it, tightened it all up and all seemed good. Anyway, MOT certificate was duly granted (happy days!) and I set off home. Car drove perfectly, turned up the EBC and saw about 17psi at one point and the car was like a rocket ship (turns out it was being in manual that made me think the auto box was problematic! In D it set off in first and worked flawlessly.) BUT... got about 5 miles further towards home and I noticed the car wasn't boosting again.... Like zero positive boost. I was nearly back by that point so limped home. Running rich as would be expected. The same boost pipe wasn't off again, it was rock solid so I drew a blank there. Anyway, I have been back under it tonight. Checking everywhere for boost leaks (like huge ones) and I have been through every bit of pipework I can think of and can't see what could be the issue? Anyone got any ideas where to look ? I am planning to do a boost leak test (got to rig up the kit) but this isn't not holding boost, it's not making boost and super sluggish. It just won't get on boost now. I cant see how a boost leak that isnt a pipe off could cause such loss!!! A vac line wouldnt cause such a huge drop either surely? (and I've checked them and they all seem fine) Turbo seems sweet, no shaft play and in very good condition so I don't believe that is the cause at this stage. Wastegate stuck open? ? All help appreciated Edited July 1, 2016 by and1c (see edit history) Quote Link to comment Share on other sites More sharing options...
and1c Posted July 2, 2016 Author Share Posted July 2, 2016 Will recheck all boost pipes in the am, check it's not blown off the collar but still looks connected Quote Link to comment Share on other sites More sharing options...
mellonman Posted July 2, 2016 Share Posted July 2, 2016 Can you still hear the turbo it will be louder with a pipe off , but im pritty sure its just as simple as that, the thing is if you get no boost from a turbo means the sharft is not spinning which would conclued catastrophic failure and engine oil would be passing the seals so you would know about it Quote Link to comment Share on other sites More sharing options...
and1c Posted July 2, 2016 Author Share Posted July 2, 2016 Cheers mate. Yes I could definately hear the turbo louder yesterday when boost went. I suppose it has to be a hose hopefully...?Going to go out for a round two shortly so will post back then. Thanks Quote Link to comment Share on other sites More sharing options...

Result!!! getting boost again! Got an issue with the auto box now though I'm sure. Will make a new thread! cheers Quote Link to comment Share on other sites More sharing options...
