Turbo blow in a 1999 Sharan 1.9 TDI

I have a Sharan 1.9 TDI of 99, which I bought secondly. By accelerating from 2500 laps especially on the road above it sounds like an air escape on the left side of the front of the driving position that rises of intensity with the revolutions (not a whistle). I don't know if you have a loss of power, since I have not had any other Sharan the same and I don't know if this is normal. The vehicle is going well, but I think it could have a little more "strength" in those cases, not much more, but a little. I think it could be a leak in the admission of the turbo, it causes some crack or pore in some sleeve. Someone could help me to know where I can get information, or if on the contrary this is normal.
Thanking the help in advance, receive a greeting from a new friend.

Hello, you have to check if any hose is with any crack as far as possible the turbo outlet to the engine that is where there a lot of air
