Piston Choice, Hypatec Or Endurotec?

[megamannz123]

I'm a little confused about which piston to buy.

I am looking at the Hypatec and the Endurotec for my 5K. From what the company website says the Hypatec sound better quality, but they are cheaper than the Endurotecs? Has anyone used either of these, or know which is better quality? I can't get into the shop to have a look at them side by side to compare.

 

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 500°C for 9 hours and then water quenched to create a single phase alloy. The second stage involves heating the piston to 180°C 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.

Endurotec® pistons are sourced from various world class suppliers. Make no mistake, these pistons are not seconds or factory rejects and are all manufactured from quality eutectic alloys with T5 heat treatment that are basically the same as many other premium brands.

Every Endurotec® piston set comes complete with comprehensive fitting instructions including piston to bore clearances and are presented in dynamic Endurotec® livery.

You were looking at buying those ones springersrolla is selling?

It depends on your bore size. I supplied them to him and when they were ordered thats all they had in stock in d-dish and 1mm oversize.

Yeah I have been chatting to him, what brand are those ones? hes away till thu and thinks they are Hypatec but then with the cheap price I found online for the Hypatec $105 he thinks they may be Endurotec

[megamannz123]

oh yeah, 1.0mm over size bore. So his will fit.
