It will not be very loud at high rpm though. Link to comment Share on other sites More sharing options...

bangm001 Member 307 Member For: 19y 7d Posted 09/04/06 12:23 AM Share Posted 09/04/06 12:23 AM I heard somewhere on this forum, that is this begins to occur much louder than normal, or previously, then you may have loose/missing turbo bolts and or loose manifold bolts, try checking these all first, they are located under neath the heat shields on the LHS. b**ch of a job realy, but I think that you will find that these will be loose. When was your last service? Look, id just do it anyway.. Also, the cooler weather seems to have a slight effect on this if they are all normal. Let us kow how you go!Cheers!

So no more spooling sounds, but the flutter is still there and pretty audible. My car's a stock 6spd manual. Link to comment Share on other sites More sharing options...
jasper361 Member 407 Member For: 19y 10m 27d Location: Brissy Norf siide Posted 10/04/06 04:49 AM Share Posted 10/04/06 04:49 AM I am confused! I thought 'turbo flutter' was bad, as per this extract from the turbosmart website.The “flutter” noise reported by many excited enthusiasts may sound good but is actually very unhealthy for the turbo. The “flutter” occurs when upon shutting the throttle, air caught between the free-spinning turbo and the shut throttle. The consequent back pressure forces the air back through the turbine blades. This process, more commonly called “cavitation” places enormous loads on the turbo and can lead to premature wear of the turbo bearings and other load-bearing components. The cavitation or “flutter” can be fixed by either fitting a blow-off valve onto a system that hasn’t got one, or making sure the blow-off valve is matched to the output of the turbo and is not working outside its flow capacity and ensuring the blow-off valve is set up correctly.Or is the flutter you are talking about actually the Wooosh sound of the BOV venting into the intake?
