The main characteristic that makes forged pistons excel in high performance applications is strength and durability. The high silicon content of cast pistons makes them brittle compared to forged pistons. Silicon gives the metal lubricity and is mixed in the alloy to limit heat expansion.
How much HP can forged internals add?
Stock cast pistons will limit you to 5800rpm, but cast pistons will hold more than 500hp. It is good to 7000 for forged pistons. It all depends on your goals and what you need to do.
Do I really need forged pistons?
Forged pistons should ALWAYS be used in nitrous applications, supercharged applications, serious street performance applications, and racing applications. ... Just remember, the lighter the piston, the less kinetic energy and stress gets put on the rod cap.
