Considering my plans for this engine, I need some clarification on overbore pistons. I know that the limit is 1mm and most have done .5mm, but with all this stress and heat, I don't want to remove any more than I absolutely have to, for both strength and as to NOT increase the CR above 8.5:1. So, is a .25mm overbore possible? That would be what ... .010"???
