Manufacturing
Valve Pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilised.- Piston Crown shapes designed to promote maximum Intake Charge efficiency through scavenging mixture “Cross Flow” during intake and exhaust valve overlap. More fuel and air equals more horsepower!
- Pistons designed to optimise squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.
- Complex Piston skirt profiles that reduce power robbing friction, yet promote stability in bore for optimum ring seal. Wiseco has added skirt coatings to the long list of standard features on our stocked Sport Compact pistons!
- Precision machined ring grooves with proper orifice/accumulator volume using calculated groove root diameters and axial widths, featuring excellent surface finish and flatness providing maximum ring seal and minimises blow-by and oil consumption.
