Improvements in performance turbocharger durability can be attained by analyzing both the physical and dynamic aspects of turbocharger failure observations. Design consideration of the severe operational environment to which a performance turbocharger is exposed can add significantly to its probability of survival.

Performance turbochargers utilized for motorsports applications have historically suffered from inadequate bearing systems. Much of this problem is attributable to the original design concept of commercial turbochargers as applied to diesel applications. Analysis of current turbocharger bearing design philosophy as well as alternative hybrid design considerations have shown that many of the operational inadequacies of performance turbochargers can be resolved.
