With the car strapped down on the dyno, the ARE staff found that the serpentine belt would tend to walk off the front of the tensioner pulley at very high rpm. It seemed the OEM tensioner just didn't have the necessary spring pressure to keep the belt taut. Already familiar with this problem, Katech whipped up this billet aluminum manually adjustable belt tensioner. This component was developed for the C5-R Le Mans race program when those guys began having the exact same problem. View Related Article
