Hi, I did drive other stand turbo copen found a little different, I can hear a little whistle of BOV when I boost gas. But when I drive my copen I can't hear any voice from BOV or turbo. Is that turbo not working properly in my copen? Can anyone tell me when the turbo work? Around 3000rmp?
It depends what type of air filter is fitted. If they had one of the D Sport ones for example, you would be able to hear the BOV. If the turbo wasn't working properly you would notice a dramatic reduction in power & maybe some blue smoke out of the exhaust. On a standard Copen you won't hear the BOV.
