Variable cam programming software developed in house allows Wiseco to produce high-performance shapes unique only. Crown thickness and ring lands designed for power adders such as forced induction turbos blowers notorious oxide. Stability is important for proper ring seal, reduced friction, and quiet operation.
Some forging alloys expand more than casting alloys, but each Wiseco piston is designed with the proper installed clearance to produce most power, least wear, and best seal at running temperature, for application. Forgings have condensed grain that is aligned to the features of part, which produces higher mechanical properties, and resistance impact fatigue.
