Forged High Performance and Racing Wiseco Pistons Features

Wiseco Pistons are recognized globally for their research and development of race winning pistons. Wiseco takes advantage of their experience from being involved with highly refined racing engines used in premier professional racing series. These include many diverse engine types, everything from single cylinder dirt bikes in AMA MX and SX, multiple cylinder street bike engines in Moto GP and Superbike, NHRA Pro Stock V8 engines, to ultra sophisticated Formula 1 engines. Lessons learned from involvement at the top levels of motorsports and powersports competition helps Wiseco design and produce some of the most cutting edge, high technology pistons currently available.

1. Valve relief areas are specifically shaped to allow maximum airflow. The valve pocket areas are machined to dimensions that work with stock valves and also allow the use of larger than stock valve diameters and high lift and duration camshaft profiles.
2. Piston tops are shaped so as to provide the greatest possible intake airflow by taking advantage of the scavenging effect provided during the period of intake valve and exhaust valve overlap. This helps draw more air and fuel into the cylinder for greater torque and horsepower!
3. The top surface of the pistons are designed and machined to provide superior quench effect. This aids in the prevention of detonation as well as the negative effects of pre ignition. This allows for greater compression and the potential for more power than a piston that does not used optimized quench areas.
4. Ring grooves are precisely machined to provide the best possible ring seal to increase efficiency and power while also reducing blow by and oil migration past the ring package. An accumulator groove is also used to further improve ring seal and performance.
5. Wiseco pistons are machined from raw forgings that are produced in a ISO Certified world class forging facility that that takes advantage of the most current technologies. Wiseco forgings feature complex shapes, advanced materials, and use aligned grain flow tech to provide an extremely strong base forging to machine the pistons from.
6. The piston skirts are designed and machined to precise dimensions and profiles which aid in stabilizing the piston in the cylinder bore to further improve piston ring seal. In addition the skirts are designed to minimize friction, further enhancing the performance of the engine by reducing internal frictional losses.
