bru00z Member 14 Member For: 15y 5m 14d Posted 25/11/09 12:30 PM Share Posted 25/11/09 12:30 PM I have a reasonably new FG F6 and have only recently been getting into the higher rev range and have noticed the induction noise seems much louder than while running in. It actually sounds and feels great but I am worried there is a leak somewhere. I have checked all the joins from the airbox to the turbo plus the boost seems normal. It makes no real induction noise while revving the car at a standstill but have a listen to this!

Does this sound normal or should I be worried?Cheers,Alex Link to comment Share on other sites More sharing options...

I do like the way it sounds but dont want to cause any damage to the car!Might have to get the dealer to check it out. Link to comment Share on other sites More sharing options...

I tightened it and went for a drive but the noise is still there. 310_FSX can you have a look at this hose for me and let me know if it goes over the plastics lugs on the airbox outlet or sits up against them?I have included some pics of mine where you can see th plastic lugs.

310_FSX Donating Members 126 Member For: 15y 1m Gender: Male Location: Brisbane QLD Posted 26/11/09 12:33 PM Share Posted 26/11/09 12:33 PM I have recently changed my factory air box for an SS inductions type. (If you like noise you would enjoy one of these) If I can remember correctly when I was changing it over the connection of the hose to the air box just sits up against the lugs. On the throttle body end the piping is different and has a locator lug assembly which keeps the pipe in the correct plane so to speak. From the noise I was hearing on your recording I would be looking the other side of the block where your turbo connections are. Sounded like air escaping under pressure rather than being drawn in. But hey if your just running in I would be getting the dealer to cast an eye over it... dont want to risk anything nasty happening Link to comment Share on other sites More sharing options...
