hypers are not strong, but think of them as the bare minimum tool needed to carry a ring package, which is what does the work in a N/A situation. you can run them with tighter clearances which allows you to shorten the skirt, and they are significantly lighter than a forged. But if you are creating cylinder pressure beyond N/A, (nitrous, turbo, etc.) you need something with more beef.pinto gt with wood trim

They do well in 100+psi diesel applications, but you don't have to worry about pre-det
Forged aren't as durable for a driver because of the reduced piston to wall and no steel ring lands

I don't care what some slide rule engineer deems acceptable to get emissions down and a high percentage of engines out of the warranty period. If it's a hot rod engine, and you want it to be tough, put forged pistons in it. Even if it's n/a for now, you might want to do something more fun with it later and you won't want to regret your cheapass decision.When the government pays, the government controls.
