Nope, not here. Only problem I had was the idle pulley running too close to the belt passing up the other side; had to put a little sim between the idler bracket and the sprintex (was making a claining sound at low RPM.)Is there anyone having bearing noise at cold start or rainy weather?
I think its from idle pulley.. but I am not sure...
Release/remove the belt tension, and see if it that pulley rolls freely, otherwise, check supercharger oil level and/or change it.... You'll get some churping from your belt if you don't cut/slice (when cutting a wider one down to four ribs) cleanly, making sure not to have any extra width hanging off the outer rib.
