I know it's chavvy as fuck but I like the turbo flutter sound of cars with no BOV's (and so does the new bird) so I blocked my BOV's today to try and achieve that sound but it wasn't having it. It was louder and did sound nice but didn't get the flutter? Iv spent all day trying to find a video of a 335 doing it but can't find anything which makes me assume it can't be done on this car. Anyone have any idea why??
