In addition, in-house dyno testing gives Wiseco the ability to develop state-of-the-art technology such as new shapes, coatings, and components, and lead the industry through rigorous R&D. Linking all segments of Wiseco’s organization through design, testing, manufacturing, and distribution allows us to fulfill market needs with minimum lead-times.
Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produce higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.
Piston Engineering
Wiseco’s detailed skirt shapes and profiles are very specific to each application. Variable cam programming software developed in house allows Wiseco to produce high-performance shapes unique to only Wiseco. The skirt shape (barrel/cam) is one of the most functional areas on the piston, and provides stability and smooth operation in the cylinder bore. Stability is important for proper ring seal, reduced friction, and quiet operation. Each skirt shape is designed for a specific running clearance, based on coefficient of thermal expansion of the piston alloy. Some forging alloys expand more than casting alloys, but each Wiseco piston is designed with the proper installed clearance to produce the most power, least wear, and best seal at running temperature, for each application. Comparing installed clearances on cast vs forged parts is not indicative of the running clearance at temperature. Wiseco engineers have a strong background in all forms of racing applications, and produce the best shapes and designs in the industry.
