As the title says and I know this has been Beaton several times. My issue is I have a d1sc procharged cobra. It has an innovators west 10% OD pulley 4 inch blower pulley and an American racing solutions tensioner. The only other thing I had to change was the idler across from the tensioner it was a 76mm we had to put in a 70 mm for new tensioner to fit. I keep shredding belts I don’t know what to do belt is tight as hell. Should I try going back to oem tensioner with the 76mm pulley or would going 8 rib fix my problem. I hate to drop another grand on pulleys idk.
