a blow off valves 'psssshh' sound, its the sexiest noice that car can do!
but u probably ment turbocharged, not supercharged? or if u did mean supercharger, do they have blow-offs in those too?
look at the dynopaper down the page, ~430hp and 765nm of torque... what about a turbodiesel because we have so much turboengines in s2 anyway...
there is no doubt we need more diesel and boost to s3
