...them. Personally, the whole dyno number thing is stupid, unless you want to have that 'HOLY GRAIL' dyno sheet to wave around all the time. You won't be 'icing' your IC or IC's all the time. However, I would entertain the idea of having a CO2 setup where I could occasionally spray my IC's during street driving just to feel the rush of additional power created by the freezing process!! :) Is that what one could expect on the street by freezing the IC's or IC on some runs???
