hi everyone, i have a concern about my engine cause when i accelerate i can hear a loud whooshing sound from the engine never heard it before but i can only here it when my window is down or is it just the turbo?

Mines being doing it since I bought starting to think its just the way they sound as I have replaced most culprits, but if it definitely wasn't doing it before on your car but is now then I would say boost leak, but usually get other associated symptoms ie, increased fuel consumption and power loss, so if neither are present its either very small leak loose clip or something, or just the turbo noise like you say.
