I have a 2.6 VMP pulley along with a 10 percent crank pulley and had to replace the belt twice for slipping/squealing issues. After replacing the belt no slippage or squealing was apparent. After a week the slipping/squealing issue came roaring its head back. Then i bought a steeda adjustable idler to help tighten the belt with the same issues. My guess is my belt is to long to begin with, can you please chime in with the belt size you used without having any problems with squeal/belt slip. Thank you very much.
