Hypatec Liquid Forged Pistons

[2LV8ETR]

Hey guys,

I have done a search for Hypatec and have come up blank. Maybe it's me, but I thought that there would have been some info here on these slugs.

My main question is: Has anyone had any experience with these, good or bad? I'm building an RB30 and my main goal is 400hp, no more than 500hp. I came across these and they're pretty cheap by comparison with big name brands.

Usually cheaper means poorer quality, but if you don't ask, you'll never know.

Any info would be greatly appreciated.

Thanks in advance guys.

Hypatec® has developed its Liquid Forged™ range of pistons with a vision to create a new dimension in piston manufacturing design and technology.

Manufactured from high silicon alloy with T6 heat treatment using advanced high-speed two piece tooling that is specially designed to withstand the huge forces needed to manufacture a Liquid Forged™ piston. Combine strong high silicon T6 heat treated alloys and squeeze casting technology and you’ve got a Liquid Forged™ piston that is designed to perform.

Hypatec® Liquid Forged™ pistons provide great strength, excellent heat dissipation and less thermal expansion in a piston that is strong and tough, yet easy on cylinder walls. Low thermal expansion qualities mean that tight clearances can be used saying
goodbye to the rattly pistons of old during warm up.

Plus, Hypatec® Liquid Forged™ pistons come complete with cutting edge design features that include; lightweight full skirt design for extra strength, pressure and splash fed pin lubrication, ten drilled oil returns for first-rate oil control and race style tapered pins. All this adds up to reliable everyday use in high-performance street engines as well as being suitable for use in high-performance race engines.

Hypatec® Liquid Forged™ pistons can be purchased with cast, chrome or moly Hastings® piston rings however, Precision recommends Hastings® Powerflex® plasma-moly file back piston rings. Hypatec® Liquid Forged™ pistons are available to suit popular American and Australian V8 flat top applications and Nissan RB30 Turbo.

Thanks for that info man, it was there when I looked it up.

I should have elaborated a little more as to what I'm after. I'm needing info on people's personal or second hand knowledge on the performance and/or durability of them.

As an example, someone who has bought them and has been flogging 500hp@9000rpm with no issues, or someone who had them crap out after only a few months.

They are cheap, but I don't want them to let go and cost me more in the long run, but if they have a good rapport, then it would improve my confidence in giving them ago.

That info above makes them sound the same/similar to Hypereutectic pistons?

Okey doke.

I have done a fair bit of research on various forums around the globe and I thought I'd just note my findings in case someone else asks the question about these pistons on this website.

The general consensus is that they are a good piston for NA and NOS purposes, and have been used with great success in high (800+hp) power outputs, but are extremely prone to failure under detonation in forced induction applications. As long as you are conservative with the timing and run rich, you'll have no issues if running forced induction, not worth the risk in my opinion.

As a result, I'll pay the extra and go fully forged (CP, JE, Mahle, etc).

Mate of mine has a set of hyper tecs in his 500rwhp rb30 thru a glide on e85. Car has run 10.14 @ 133mph, motor is now 3 years old and still going strong, was put together by breciani racing!

Hope that helps u out!
