Need help, Turbo got weird sound

[BeCool]

Dear All the sifu,

I need help. Today i drive my car as usual to work, but after the toll, my car turbo came out weird noise. The noise started from 2k rpm to 3k rpm, jz a while only.
U know like the wolf making noise at night "nwuuuuuuuuuuuuuuuu"
then after 3k rpm the noise stop immediately.

may i know whats the problem actually?

Ok,serious...I think better check the wheel lol....Take out the turbo piping and tembak with compressor air and see whether the sound comes Wuwuwu or Sheeeeeeeeee or even kau Wof wof wof...joking only ah.
