Default woshing noise

ok just asking if this is normal, i have had turbo Cars before and i could never hear any "induction" sounds from them unless there was a Boost leak, but this Volvo when i boot it i can hear a loud Air being Sucked/blowed, is this normal or could there be a boost leak?

i also get a little bit of black smoke when i boot it, not just a little puff but all the time when i am wide open.

i dont have a cone filter, only standered paper filter fitted.

Edit:
This Car is a 1998 V70 2.5 auto TDI

As long as it's black smoke it's fine.That's the way diesel is suppose to burn in it's natural state without any emission control ...
If it's grey or white smoke that's a different matter and your expelling unburnt diesel.

Check for split or failng charge pipe or inter-cooler.

If it's charge pipe you'll know eventually as it sounds like a steam engine and won't go above 40 mph!
