Trillion Posted July 12, 2014 Share Posted July 12, 2014 Hey folks, Drove a 350 mile round trip yesterday in my Focus ST and everything seemed fine. Left the car off for 30 minutes or so and started her up again and noticed that as soon as I drove off once the turbo just spooled up there was a slight whirring noise, but it was a slow whirring, almost like what you'd expect from a leaf in a slow moving fan blade (on and off at a constant pace) but louder and more metallic sounding. It doesn't sound like the blown turbos I hear on youtube where the noise is constant (it's a similar noise BUT it's happening at a slower rate almost like the turbo is running very slowly however the car runs absolutely fine during this period. After about 30 seconds of driving it goes away and the car runs completely normally. Just find it pretty concerning as I've only just spent £300 on ignition coils/leads. Anyone know what this might be? Mike Video here (very quiet at the parts where it makes the noise but loud at the start) Quote Link to comment Share on other sites More sharing options...
troy45 Posted July 12, 2014 Share Posted July 12, 2014 Pretty difficult to tell anything from that video, I couldn't get the volume up very high and hardly heard anything tbh Quote Link to comment Share on other sites More sharing options...
troy45 Posted July 12, 2014 Share Posted July 12, 2014 Seeing as you're in Cheshire, if you want an expert opinion pop over to Collins Performance in Congleton and ask Gary to have a look at it. Nobody better on ST's imho Quote Link to comment Share on other sites More sharing options...
Trillion Posted July 16, 2014 Author Share Posted July 16, 2014 Haven't had it checked out yet but I suspect it may be the fan belt, anyone? Quote Link to comment Share on other sites More sharing options...
