Thanks Ryan for info. my skepticism is with nikisil not blocks being stressed members or ribbing. motors have been stressed members in race cars for many years. If there is such considerable upside to this process why aren't any major manufacturers putting this to use? Things being what they are with mpg, weight, performance, and emissions. Thermal advantages and friction reduction also. Big difference in bolting in some new jugs or pulling a motorcycle motor rather than pulling your cobra or whatever motor and replacing or recoating if possible. Alot of considerations other than who can save some pounds. I still wonder about long stroke motors and associated rod angles effects on coating wear over the long term. If that is a problem what are your options for remedy?
