Agreed.. Ambient is ambient.. Without evap or refrigeration whatever the outside temp is is what you can achieve. Cummins have run a water to air cooler system in the 6bt's for a while.. I've seen it on tractors, but never got my head around it.. I've seen systems that mist water over the front of an intercooler to help it cool more.. This is said to work quite well...
