Helo, I just came across something which I have wanted to know very long ago...
Why cars like Evo or Wrx... When their boost comes n change gears, we can hear the sound from the blow-off valve... It is because they are turbo-charged engines right??
As far as i know, Volvo S40 also turbo-charged engine isn't it? Why they dont have blow-off valve sounds ar?
shoot me :shocked: if my question is stupid..
cheers
