hi guys!

from the begining of my gt ownership i hear subtle very quiet whistle when accelerating.

this whistle comes from engine area - i hear it when i am driving the car.

ive never had twin turbo w12 6.0 or other twin turbo super car so can not judge if this is normal or not.

started to explaing it to myself as normal running turbo etc but maybe i am wrong and i need to pay attention to it as it is symptom of smth to fix.

anyone experienced can tell me what it is?
