I didn't say it wasn't benificial, I said it wasn't needed. Generally on a n/a car a cold air or ram air, or some kind of crazy intake, set up is in place to help colder and denser into the engine. Obviously more oxygen per volume of air is going to produce more power.
In a turbo car you don't need to worry about crazy intake stuff to help the air be denser, it already is because of the compressor wheel of the turbo, but one of the byproducts of the compressing process is that the air becomes extremely hot. Very dense hot air entering the engine is a bad thing unless you like detonation.
Now, a higher octane gasoline such as cam2 or c16 will be stabler and not as likely to predetonate with the hot hot air coming in. I run 25psi on the kind of sidemount that any self respecting bling master would laugh at...but I also run 117 octane gas and can get away with it with great timing advance.
An intercooler is still extremely useful, especially in a high boost situation, the lower temperature charge air will help prevent detonation. Couple that with high octane and you can't lose, unless you lean it out and melt something.
I'm not corky bell, but to me running very high octane is much more important than a solid intercooling system...it will supress knock much better when you are on the drag strip.
Now for every day driving around, when the octane gas you use is 91-93 and the boost is still up above 12 psi, an intercooler is needed. You might even need one on the roadcourse where you guys see much higher overall temps than me.
