I used DeepL to translate 吹かす originally and thought the "behave as" translation was what fit, but in the way you explained it, it only makes sense for it to be "rev up" or "accelerate". This is a type of verb that makes me love the way Japanese people think, since it can probably be both about accelerating in a more "aggressive" manner or about smoking too, but I'm guessing the mental imagery is the fumes and smoke that come from both actions. I wonder if the "behave as" translation has to do with the transformation jutsu of ninja
But in all seriousness, since jisho says one of the meanings can be interpreted as "to put on (an air of)", maybe this visualization isn't far from accurate
what do you think?
