Audi RS4 Avant B7 w/ PES Supercharger (556HP) - SOUND!

This time I have filmed an Audi RS4 Avant B7 equipped with a PES Supercharger producing now a staggering 556HP! Video shows the car in action racing against other supercars, like a stock RS4 Avant, Mercedes-Benz C63 AMG and an Audi R8 V10 Spyder! Liked the video? Click the like button, comment, and subscribe!
