Just like the other piston post, go to "Products", then Speed Pro, Tech Highlights, then Pistons. Great explaination of Hyper vs Forged. PowerForged is marketing name.
Typically for street, Hypers are better because of tighter tolerances, which also provide better emissions. Forged or PowerForged are much stronger pieces but need looser bore tolerances to provide room for the temperature expansion of the forged pieces. Many pros and cons of each, I'm sure someone (self proclaimed expert) will chime in on this one for sure. But basically, this is the abridged version.
