Re:Hyper Utectic pistons?
Uh, why Is every one bitching this guy out. He made a post that had a few valid points, and the people that jumped all over him had no valid info to add or any idea of what a hyper eutectic piston is. For NA a hyper eutectic piston is much better than a forged piston. what makes something Hyper eutectic is the percentage of it's constituents and the temp at which it is heated when formed. Whitey can tell yall I thought he said he was a mechanical engineering student.

"Everybody" bitched this guy out because he is talking out of his *** and came off like a know-it-all ********.
Like I said, we run boost on our motors so these pistons are ----. Why do I need to into more detail than that? Do you want the schematics, design, heat, pressure, load, and burn tests of each individual metal of each individual piston?
Here is a start for you:
http://www.lcengineering.com/TechNotes/TechNote41.htm
http://www.beckracing.com/page11.htm
Hypereutectic 390 refers to a unique aluminum piston alloy that contains dissolved and free silicon. The material can be T6 heat treated to high strength and stiffness. Non-heat treated 390 hypereutectic alloy aluminum has slightly less strength than conventionally cast F-132 aluminum. With this in mind, we caution the reader about the use of non-T6 heat treated O.E. design hypereutectic pistons for high performance. Silvolite and others do make replacement-type hypereutectic pistons that are worthwhile for stock replacement applications. Original equipment design is almost never suitable for performance applications.Shall I continue?

Re:Hyper Utectic pistons?
They are STOCK PISTONS!! Why do we need stock piston back in our cars?

So they are still cast pistons? Eh, I'd have to skip on that one, but I've never heard of these "Hyper Utectic pistons".
hypereutectic i think its spelled.
they are mostly for high comp NA uses.
they're in my small block...
they are stronger than cast and don't expand like forged alum. no slap = longer life

they are cast, yes, but are then subjected to a heat-treating process that makes them very strong (though their kryptonite is detonation; and don't drop one as it will break). much like high silicon forged units. on the pro-side: they are very thermally stable so piston-to-cylinder wall clearance is very tight (see less noise, less oil comsuption, less blow-by, etc). i had a very long discusion with a KeithBlack rep at sema (KB is the most well known aftermarket supplier of HU pistons) and asked him WHY DON'T YOU MAKE THEM AVAILABLE FOR IMPORTS?. REPLY (in my own words): because people are idiots and we know there will be a lot of failures before everyone in the import market learns to install them correctly (they require a large ring-end-gap or the top land WILL be broken in short order). a piston is a piston, V8 or honda 4.
yes i have strong feelings about these because they have made me proud in many domestic engines. and they can be MUCH better than $100 cheaper than pos shelf stock forged (offset pins for one thing).

So you're telling me that a certain piston manufacturer told you that he doesn't make them for imports because the import tuners don't know how to install them?
Get ------- serious dude. That's the lamest thing I've ever heard. You're obviously domestic biased and are blinded by your "good buddy" at Keith Black. I doubt you ever had any conversations with them anyways. If you did, they propbably told you that to get your annoying *** away from their booth with your retarded questions. In ending, your mom is a -----. Have a nice day. 
remember the old twin turbo lt1 1st gen camaro on here... the purple one... hypertecnic pistons.
lt1/ls1/ls6 i believe all have hu
one year of foxbody stangs have hu, they switched back to forged then back to hu in the next gen to present.
my hypers were $140 dollars for 8.
the cast OEM pistons for my honda were $140 for 4.

Nobody gives a ---- what you say you've done on the internet so save your lame *** stories.
Take your piece of ---- cast pistons and stick them up your ***, bitch.

Re:Hyper Utectic pistons?
he also said PEOPLE are idiots, he said nothing about people who work on imports are idiots.
he also stated correctly that lots of v8 people had problems installing them, and therefore broke a lot and they recieved a bad rep.

We are running boost on these pistons. Understand? He said it himself:
