wobbly/spinning sound

I hear a wobble from the engine for a few seconds when i accelerate from a stop. anyone know what this means? Seems to be more pronounced on a cold start.

Maybe the sound of the turbos? Is it only heard under hefty acceleration?

Yes, it's completely normal, it's just the sound of the turbos spooling up and maybe some wastegate noise. I would be worried if that noise wasn't there, it's just a characteristic of a turbocharged engine. Some people, myself included, like the noise.
