Tyson Posted January 16, 2012 Share Posted January 16, 2012 Is it a whistle or a drone ? If its a high pitched whistle this is normal and nothing to worry about. Link to comment Share on other sites More sharing options...

Swampy442 Posted January 16, 2012 Share Posted January 16, 2012 When the bearings are going the turbo makes a sort of woooOOOO noise that increases in pitch as boost increases, whistle is perfectly normal. Link to comment Share on other sites More sharing options...

That is actually a good explanation! Looks like you got your car recently, get a video up, whistling is fine. Link to comment Share on other sites More sharing options...
Guigsy Posted January 16, 2012 Share Posted January 16, 2012 There is a whistle then there is a WHISTLE. They do whistle. But if you dont know what it's supposed to sound like then you wouldn't know a big one from a small one... Link to comment Share on other sites More sharing options...
