Hypatec is a high quality performance piston. Hypatec pistons are all manufactured from 11-13% silicon alloy combined with T6 heat treatment to create a piston that is stronger than many other pistons. Plus, every Hypatec piston is manufactured utilising state of the art CAD/CNC diamond tipped machinery. The end result being a piston that can withstand the severe loads associated with today's performance engines.

High silicon alloy is the preferred material for most cast pistons because it provides greater strength and greater scuff and seizure resistance. The silicon acts as small insulators, repelling the heat created in the combustion chamber, allowing the combustion chamber to retain its heat, creating a more efficient combustion process while the piston actually runs cooler.

Hypatec pistons are heat treated using the T6 heat treatment process. This is a specialist process which is performed in two stages. During the first stage the piston is heated to 500C for 9 hours and then water quenched to create a single phase alloy. The second stage involves heating the piston to 180C for 10 hours and then allowing it to air cool. As a result, the alloy hardens to form a copper aluminium crystal, CuAI2. It is the formation of these crystals that give the alloy its strength.

Hypatec pistons are manufactured by original equipment piston manufacturers. Because Hypatec pistons are developed directly from the needs of engine manufacturers, the latest design features are used in many Hypatec pistons. These developments include; anodizing, alfin inserts, ceramic fibre squeeze casting and gallery cooling. They are all original equipment developments and are included in the Hypatec piston range for the aftermarket.

Piston set does not come with rings, sold separately.
