awseome video,doug the owner and owner of mrc rents my boss's unit next door,i went in that car when it was 550bhp and it was immense,no wheel spin just pure grip.and now it has over 750bhp!!!
u should hear the 4x4 rolling road hes got with some cars producing 700bhp on it,sounds awesome,i live the other end of this town and can hear the cars on rollers at nite time.
the s4 at the moment is in the corner of his yard with engine removed as hes extractin more power from it
absolutley awesome car
