Have you watched the video I linked to? Let me know if it sounds the same to you. I have brought mine back to the shop and they said the same thing. I started using gas without ethanol and noticed a reduced sound. Not sure if I am just getting used to it or not. For the longest time I thought it was a belt shimming on a pulley but the noise was coming from the other side. Let me know of this helped at all?

Question please re: Jackson Racing SC kt.. I had mine installed recently, got some fairly loud whistle / squeal at idle, which quiets if I rev to 1100 rpms or start to drive. A Reputable SoCal shop did the install. They claim this is "normal" but I wanted some indipendent verification. I saw that you also described the squeal in your post. Did you find a fix?? thanks! robc
