Engine Internals & Assemblies


Do forged internals add power?

The high silicon content of cast pistons makes them easily breakable compared to forged internals/pistons. Forged pistons are heavier than cast ones, but this is made up quite quickly by the ability to provide a higher compression ratio inside an engine which enables engines with more power and revs overall.

Forged means that the component has been heated to temperatures near melting point and then pressure distorted under high tension. This process creates an aluminum or steel bloom which can be pressed into shape with dyes, respectively.
