Hey all... Just a quick question, after taking my fd for a drive tonight I noticed a weird sound coming from around the turbos.. It kinda sounds like the stock BOV sound but a little more muffled and somewhat metallic(probably not a good sound). Has anyone heard of anything like this? It only appears when the car is under boost and it happens very low in the RPM range ~3500 rpms. The car still makes good power and the boost itself is normal.. any ideas??

Thanks,

Matthew Walsh

 

bump?

 

Is it like a "fluttering" sound?

 

yeah.. kind of.

 

Any Ideas?

 

If it's a mettallic sound while you're on partial throttle and goes away as you increase to maximum boost then it's the prespool BOV. You must have an open filter?

 

It may be air-pump moooo....??

 

Thanks fella's... I'll check out these possiblities and report back.
