John, the pistons will take whatever the engine can, right up until it pings. With all the variables involved in mass production pistons and a thousand things that could go wrong that are not KB's fault, I think it's one of those "Publish it so we have an out" when something does go wrong that is not thier problem. They can take a little detonation and ping, but on a fresh build... I cringe at audible ping.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
