i have done some research and there is even a fourm on here about what i think these are but i would like some opinions on some pistons. i found what are called hypereutectic pistons which are cast but have a higher amount of silicone in them and i was wandering if anyone has ever used them or knows if they can handle 250-300 hp. some of my questions were awnsered on the other fourm but i am just making sure here because i dont want to do this twice.

 

same here id like to know about the pistons also, there is a guy sellin them and this is what he posted:
Hyperutechtic low compression (8.5:1) pistons, stock bore. Hyperutechtic is a newer style metal. its almost as strong as forged and much stronger than cast. these pistons should be able to handle 17psi and higher with proper tuning.


so if anyone knows about these pistons let me know, thanks
