OK< guys! Most of us will NEVER take these cars of ours to any track at any time....so, why would we wanato spend the money (two, three or four times the cost of cast pistons) to buy forged? Or to buy hypereutectic? I was talkin' to an engine tech, and he told me that he was concerned about people using hypereutectic pistons in street cars instead of racers, said the expansion rate of the material was not as good as what was used for cast, that the cast ones expanded properly, and that many people didnt know that drag cars used special equipment to warm up their engines first, which we do not have, if we use hypereutectic ones. So...does anyone know the true deal here? Or are we just suckers for piston marketing departments? I'd like to hear what you know!
