Forged pistons are forged pistons, right? Smack them out, machine them to round, and ship them to the customer. That’s the long and short of it, right? What’s so hard about this!? As it turns out, that is not what the long and short of this is and what’s why we want you to let MAHLE motorsport educate you on the difference between 2618 and 4032 alloy used in the manufacturer of pistons. Both of the materials have their strengths and proper usages and both of them do different things when the pressure and heat of combustion are applied to them.
When it comes to building an engine, especially one that is going to see competition or aggressive situations on the regular or semi-regular, we have come to learn from the best builders in the industry that details are where winning and losing happens. Yes, you can buy the wrong piston from the right manufacturer if you don’t spec it properly with what you are trying to accomplish. It’s easy to them blame the manufacturer for selling you junk but the reality is that you failed yourself AND them by not doing the research and getting the correct pieces for your application.
Learn about these alloys and arm yourself with even more information for the next engine that you build. Everyone comes out ahead when the knowledge flows.
