thats a good point, you say 200 at 14 and 220 at 16, theory generally says 10 per 1 psi, it would be intweresting to see the inlet temp difference at this point and again at where you feel that you are having problems.although that being said, i was in china last yr and witnessed with my own eyes the cryo bottle set up being used in a high powered lancer evo 7, it had approx 600hp but when talking to the mechanic and engine builder about the bottle, they dont use it ! what happens is the air becomes so cold in the inlet that ice begins to form, damaging spark plugs and diluting the octane rating of the high strung fuel they were using causing a few monumental blow ups !. cold is good, freezing cold is not good !
