Anyone having any luck with hyper pistons? Made around 800whp with a gen3 5.3 ("weak" rods/pistons last year.)
Was considering tossing a set of forged rods and hyper pistons in an old LS1 this year. The area above the ringland looks pretty beefy on these. I ran cheapo forged power (fed mogul/TrW) hypers on a few boosted builds and rods always bent before the pistons. This would be going in an early gen LS1 and I’d like to avoid boring the motor. (.010 is the max they can even be bored I believe.) For $250 it may be worth a shot to have a lighter bigger bore motor. Also have a gen IV 4.8 I could run sitting next to the LS1.

I have a gen4 4.8 I think i'll run next year. I also have this old LS1 staring at me. I wouldn't mind the lighter block and extra bore. Just didn't want to fork out the cash/machine work for forged pistons. Considering the cheapish I-beam forged rods and hypers for it.

Was hoping some others played with them. Curious what these hypers are capable of. They look much stronger than OEM GEN IV stuff. I know we were able to push them really hard in the turbo buicks. If I can squeak out 900whp or so with them I think I'd be happy.
Since most "forged pistons" are high silicone 4032 alloys now, I wonder if they are even much stronger.
Something you have done? Any links or build thread you could direct me too?
-thanks

It just depends on how well they are made. Truck cast pistons will take as much power as you can throw at them but they are thicker than the factory ls1 piston. Those could be really good or really bad lol
