I'll stand by my statements. Based on my research, I doubt you are going to see more than 5HP. The top NASCAR and NHRA teams are using cryogenic treatment, but they are the guys that need to squeeze the last 5HP extra out of the fixed displacement and component weight limited class rules. They also use it for extended component life. The gains on dimensional stability and abrasion resistance are excellent. Not sure that I would extrapolate a single point 16L CAT diesel result, from an experiment with unknown control points, to a 6.3L gasoline-fired daily driver.
