I agree with you ONLY for the track.....and yes I have used a CO2/NO2 sprayer on my air 2 air intercooler before and it works well.
Most people don't use their vehicles for the track only.......unless it is a race only vehicle which in this case we wouldn't be having this discussion
As for not getting into boost in hot climates.....I still stand by that comment. There is not much you can do to avoid detonation and heat soak under the hood especially with a turbocharged application like mine when it is 115+ degrees outside. Unless you have access to high octane fuel (which in my case the highest I can get a most pumps is 91 octane) then your $hit outa luck and detonate too much and say bye bye to a head gasket or worse a piston
