oh and btw the cooling effect is when nitrous expands not compress....all gases have the same endotermic effect under expansion not just nitrous....so O2 would have the same cooling effect....but still the reaction with pure O2 would still cause detonation.....
and i'm pretty sure an increase of 40% O2 could cause detonation even with premium gas....N2O is about as high as you can go percetagewise of O2 without causing detonation at least in normal aplications......

Like earlier mentioned N2O breaks down to N2 and O2 in temperatures above 570 deg F. This temperature will be reached under the compression phase, and it should take heat energy to breakdown N2O. This will also have a cooling effect similar to the one methanol has when it vaporise under the compression phase.
Otherwise N2O also have a cooling effect while expanding in the intake.
