Re: Supercharger Noise - Take a listen
I can't believe it has been 3 years since this thread was started. A lot has changed. Using an iPad now and not a PC for starters. Here is the latest on the SRT-6 SC noise problem that a number of you fine folks have or are or will experience given enough miles on the car and your driving style. This thread first off addresses a particular type noise that is associated with the pulley on the front of the supercharger. The dealer may be incorrect if they tell you it is something inside the SC. A simple test can prove that this is or is not the case. The trick is to not let the main SC shaft spin while allowing only the pulley to rotate. This is extremely dangerous procedure that only works at idle speed but clearly isolates the noise to the pulley and only the pulley. I do not reccomend anyone try this. Read on for an easier solution. Chances are very low that the main SC is at fault here. If you have already replaced the pulley bearing and maybe also the idler pulley, then here is your problem. You will be amazed to find out. The root cause is the rivets holding the pulley together are made of a metal that is too soft and over time, extrudes just a little bit and allows a wee bit of play to develop around the rivet holes. In the worst case, the rivet might shear off and cause the spring steal strap to fly out and act like the string on a weed eater. Solution, hit it with a hammer. Not the pulley, just the rivets. This wil actually work to remove the play and tighten up the springs back to the way it was originally how long this will last is still a mystery. See my YouTube video on the way a good pulley looks and feels anyhow one that is making a lot of noise looks and feels.
