Kopite Posted June 25, 2005 Share Posted June 25, 2005 not sure what a grawling noise means mate, have you got a boost gauge? what sort of mods you runnin? Quote Link to comment Share on other sites More sharing options...
Homer Posted June 25, 2005 Share Posted June 25, 2005 Hello mate, what sorts of mods do you have? Was this a sudden loss of boost or is it a general lack of 'kick' after 4k rpm? Do you have a boost gauge, if so what readings do you see? You might have jost blown off a pipe somewhere which is causing the 2nd turbo not to spool. Do you have any aftermarket silicon pipes fitted? Quote Link to comment Share on other sites More sharing options...
adi2009 Posted June 25, 2005 Share Posted June 25, 2005 Check all the vaccum lines and the intercooler lines mate. Also you need to give us more info such as how much boost you are seeing at different RPM's. Quote Link to comment Share on other sites More sharing options...
ADD Posted June 25, 2005 Author Share Posted June 25, 2005 the car is completely standard, it just doesnt seem to give as much kick after 4k rpm. i have checked all the pipes and there are all in tact. i dont have any boost gauges or anything Quote Link to comment Share on other sites More sharing options...
Homer Posted June 26, 2005 Share Posted June 26, 2005 It does sound like you've lost/split one of the pipes controlling the 2nd turbo. Just to check its not a sticky actuator - if you lift off for a couple of secs then re-plant the accelerator does the power come back?

JohnA Posted June 26, 2005 Share Posted June 26, 2005 .... i have checked all the pipes and there are all in tact. Have you checked all EGCV and EGCV VSV pipes? Have you checked all EBV and EBV VSV pipes? Have you checked all IACV and IACV VSV pipes? Pressure tank connections and pipes? Checked for cracks or splits? People often say 'yeah, I've checked them all' and what they mean is that they looked at the top of the engine and nothing was obviously missing. Not the same thing. Without a boost gauge it's hard to diagnose boost problems by the way. Quote Link to comment Share on other sites More sharing options...
