Are Hypatec pistons any good? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Hi all, I'm currently trying to select some Hypereutictic pistons for a stroker buildup I'm doing and cant find much info on the Hypatec range online.
Has anyone had any experience with these pistons, are they any good and how do they compare to other brands?.
thanks

i have used hyperutictic in a hot 460, i think the brand was right way not 100% on that though they were great,copped a severe beating and never had a problem with them.i used them because of cost was a issue but they were fine for the use intended.

hyperutictic are not a brand tmk..They are pistons high in silicon content so they can run tight clearances and wear very well..The std pistons in roller 5.0 are hypo pistons...Then it depends on brand..They are better than budget cast pistons...
Imo with the rod ratio 347's have these pistons are ideal...

Hypatec are a brand of pistons. The make both hypereutectic and forged pistons.

Only thing wrong with those pistons they dont like detonation. I had a bit once and it took the skirting off LOL. Forged pistons are cheap now. You can get a set of TRW forged pistons for $450.

l have used alot of the KB hyper pistons in motors , even in a blown bb chev
which made 850hp and had no trouble with them .Just make sure there is enough ring gap or you rip off your crown

Ahh I though it was a typo...I can hardly say hypereutectic let alone type it....There is possibly 2 milliseconds between Forged and hypo pistons when it comes to BAD detonation....In thin wall engines like these the tighter the piston to cylinder wall the better..Early forged pistons ran big clearances and split bores no end...More of an issue I guess with engine assembly / clearance rather that what pistons are used...

I have the liquid forged ones in a race 308 holden (cough) V8 and they have been great for 8000rpm and 650hp with a shot of nos. I would use them again in the future.

XFFAIRMONT · 07-03-2005, 19:52

Just curious, what kinda NOS shot can the hypeutectics take. I am running these and the cam i am running is supposed to be well suited to NOS. This is in a cleveland, don't think i'll risk it anyhow, but just interested in knowing.

The 308 has 430hp naturally aspirated and runs 11.9 without gas. I have only run 50hp of gas on the track and pulled 11.2 before smashing the diff. On the rolling road we have gassed it up with 200hp before it spun the tyres. The engine screamed like hell, but showed no signs of being damaged. New diff, axles, uni joint, and clutch have been installed ready to try the 200hp on the track.
