• The next step in the evolution of high performance powersports pistons
• Space age aluminum alloy maintains high tensile strength up to 700° F
• Temperature resistance is 50% higher than conventional cast pistons
• Temperature resistance improves fatigue strength and impact durability
• Hyperdryve keeps you riding longer and harder than competitor’s pistons
The images above show two cast aluminum pistons that have been magnified to 1,000 nanometers.
They were both heat soaked for 100 hours at 600° F (316° C) to simulate normal operating conditions.
It is easy to see that the conventional aluminum alloy’s particles coarsen significantly. This weakening
of the material’s bonds will lead to a sharp drop in piston strength. While the particles of the
Hyperdryve aluminum alloy coarsen slightly, showing that they are still able to maintain a higher
strength for longer periods of time.
Additional testing shows that the biggest hardness drop occurs after 10 hours of use. The Hyperdryve
aluminum alloy still maintains twice the hardness of conventional alloys, even after 20 hours.
The Hyperdrive alloy, combined with existing SPI techniques of anodizing the crowns, machine smoothed heads,
and MOS2 coated skirts, provides smoother break-ins and meets the demands of today’s high performance engines.
