first things first, the beer has just jump started my brainnow the question, a couple of years ago i had a rover 620ti (don't laugh!) which, apart from breaking down every 3-4 miles, had a fairly loud turbo whistle, the mother in law said it sounded like an aeroplane! it had an induction kit and boosted to around 12psi, now i loved the noise it made and after a stint in a 1.4 automatic Astra i wanted another turbo'd car which is why i bought the Leon, i've got used to a diverter and not a dump valve but the turbo is pretty quiet, is there any way i could get the turbo screaming
