Compressor surge. One of the best sounds but not good for the turbine.
I don't own a turbo car, but from friend's turbo car, it seems okay. Just don't do it too often on purpose.

But 0 and below where got boost? That is why no 'kepishhh'
seems like the BOV spring adjusted too tight when close throttle there is not enough vaccum to keep open the BOV...but the turbo already pumped some pressure inside the piping hence tu tu tu tu compressor surge....


me everytime drive half spiritedly sure got that sound....only way to reduce it push the throttle more and make proper boost before releasing throttle/change the gear :biggrin:

Blow off function is to release the volume off air in intake with certain pressure which can be measured on the boost meter.. if spring rate higher is too tight the boost won't comes out but if too soft u will lose the boost..normally can measured by gauging meter..if at 0 & below it will return through air filter..
..like wastegate function to reduce the volume from combustion..correct me seefu if I am wrong
