turbotrana Member 2,586 Member For: 21y 19d Gender: Male Posted 05/10/13 08:06 AM Share Posted 05/10/13 08:06 AM It only happens under load/boost but it sounds like its got a supercharger under the bonnet. Nothing at idle or even stabbing on the accelerator whilst stationary.I've poked my head around the engine bay but no clues.It sounds like loud whistle and I was thinking boost leak somewhere but just can't see anything.Any suggestions welcome. Otherwise got to put it on a dyno to pinpoint this one. Link to comment Share on other sites More sharing options...

These products are very flammable and will increase your idle if sucked into the engine. If your idle changes when you spray a certain area then that's where it will be leaking from. Keep it away from paint work. Link to comment Share on other sites More sharing options...

turbotrana Member 2,586 Member For: 21y 19d Gender: Male Posted 06/10/13 05:45 AM Author Share Posted 06/10/13 05:45 AM (edited) Went for a drive today. Definately the same noise as in the video.Is that a could be or definately turbo.If its the turbo then the tuner who did this car must have put a used BA/BF turbo in this FG as I considered the turbo to have done too few Km to be causing a problem.I guess that must be the noise when the ball bearings in the turbo start to cause issues.But then Pazzo reckons that he has heard it on low km cars.I guess alot of people will be scratching their heads as its quite a cool sound at boost (but becoming annoying).
