well we obviously run our cars richer than the n/a guys for safetys sake. and i believe stoich is 14.7:1, meaning the greatest amount of power can be made at that ratio, but the heat is just rediculous so shit melts and welds to cylinder walls.

so are the the (piston, cyl wall) materials heat resistance the sole reason for not leaning out to rediculous amounts? do diesels run the same a/f ratios as we?
