2011 XKR175 SC Pulley upgrade and engine noise
hey all..
been noticing my 2011 XKR 175 is making a fluttering sound at certain rpm's on the freeway, if I let off the pedal (rpm's) it goes away, tried it with AC off and on, in Dynamic mode on and off, and still there, I believe its a belt tensioner and the serpentine belt bouncing if I was to guess.
also went to the local dealer to see if my model had and changes to the SC and the parts guy told me there is a pulley front housing change, not sure if this has the smaller pulley that everyone wants for the extra HP but the parts guy was new and could not give me any more info... can anyone answer these 2 for me... much appreciated.
