Hyperutectic VS Forged pistons

the piston type (cast, hyper, forged) won't gain you any power in its self. the power gain comes from the shape, I.E. domed, dished, and shape of the two for flame travel and quench. if its just a street motor with no power adders for seen in the future then id go cheap and just get cast. unless you want a piston with a dish or dome that's not available as a cast piston and only available as hyper or forged in which case i would go cheaper again and run hyper. the only reason i can see buying forged pistons is if you needed them for boost or nitrous.
