I'm also in the CAI group, just to make things straight. My intercooler bypass idea is mostly for quicker warm-up. At load the intake air would go through the IC. My grille block has two independently operable openings, for the IC and for the radiator, and the latter gets opened much less often than the intercooler side.

Now that you've started this thread...
I wonder what the best temperature for the engine itself is? During normal driving my coolant temperature is 78°-80°C (172°-176°F), rises to 95°-105°C (203°-221°F) in hot weather, stop&go traffic, or hillclimbing. The fan is supposed to kick in at 95° (1st speed) and 105° (2nd speed). When the fan was disconnected the temperature once rose to 115°C (239°F) but nothing happened. So my question is: Does a diesel like to be warmer (like above 90°C/194°F), or should I try to keep it closer to 80°C/176°F?
