What Does a Forged Engine Mean?

[McRylee]

Forged engines achieve an excellent balance between high strength and lightweight. For instance, in Honda's Type R and other high-performance vehicles, forging processes are often used to manufacture pistons, crankshafts, and connecting rods. The commonly referred to all-aluminum engine denotes an engine where both the cylinder head and block are made of aluminum alloy. If the cylinder head is aluminum alloy but the block is cast iron, it is generally still referred to as a cast iron engine. Forging high-temperature metal allows more minerals to penetrate into the metal particles, thereby improving the component's strength and heat resistance, ultimately benefiting the engine's RPM increase and power output.
