Dump valve?!

[chembers]

So when I'm accelerating hardish, when I dip the clutch to change gear from say second to third, I can hear a whoosh noise. It's fairly subtle but does sound like a dump valve.

My car is a 2022 FR 1.5 petrol manual on about 6500 miles.


I can't say I've noticed it in the past. Is this normal or could I possibly have a dodgey turbo already?

I've never driven that car, but sounds perfectly normal to me. The air from the turbo needs to go somewhere when you lift off the throttle, so it's normal to hear the diverter valve open on all turbo motors, especially when you're accelerating hard and boost levels are high.

I've only driven the 1.0 and the 1.4 hybrid. It was noticeable on the 1.0 one but yes, as @mty12345 said, it's normal.
