zayd687 Member 74 Member For: 15y 15d Posted 13/12/10 02:46 AM Share Posted 13/12/10 02:46 AM The flutter is from a non working BOV. The flutter noise comes from the turbo through the airfilter. If you have a aftermarket BOV from the standard Bosch ones and it still makes the flutter noise, it can mean the spring is set to hard or the BOV is to small for the boost the car is making.I removed the cone on my FG and it made the spool noise in the turbo sound alot louder. So it must silence the spool induction noises alot.so if I wanted to make the car dead silent, without the high SPOOL NOISE and the futter. I would a ) upgrade the bov to a aftermarket one with an adjustable spring ( im thinking gfb stealth bov? )and isntead of running the pod strait from the turbo enclose it in a box.that would help sounding it dead quiet?is this correct?no offense to the guys that wanna have the whooooshhh sounds n stuff ! =) Link to comment Share on other sites More sharing options...

LET'S TAKE IT OUTSIDE!!!!! Hahaha... mine flutters with stock system due to having 3x the boost and probably due to an old BOV not releasing the gas as fast as a new stock Bosch would.I like it and enough people say it's not doing damage so I will leave it as is Link to comment Share on other sites More sharing options...
Rusty XR6T Donating Members 516 Member For: 14y 9m 26d Gender: Male Posted 15/12/10 05:02 AM Share Posted 15/12/10 05:02 AM but I thought blocking the BOV was bad because of long story short it make the turbo slow down due to reverse pressure The best one I've heard yet... it could even make the turbo spin backwards But in all seriousness please dont debate it here!!! on a side not which end of the BOV do I block off again? is this legal? is there a blow off valve that will make the flutter sound? how do I make my car do the fully sick dose that VL's have? I know I'm taking the piss, sorry im at work and am really bored Link to comment Share on other sites More sharing options...

dre Resident idiot. Donating Members 2,068 Member For: 14y 4m 6d Gender: Male Location: Melbourne Posted 16/12/10 08:26 PM Share Posted 16/12/10 08:26 PM I just installed the plazmaman intake kit (air box, pod filter) an dthe air muffler replacement. The car is otherwise unmodified at this stage but it makes a lot of noise. Massive spool noise which varies greatly depending how hard your pushing and a loud gobble gobble style noise when you back off..A have a few pics on another post. Here's one of them. I might take a vid later but if anyone is around S.E melbourne and wants to hear it I may be able to meet up sometime.Andre Link to comment Share on other sites More sharing options...
