Not quite people. The real reason an Intercooler is there is to remove the excess heat that is put into the compressed charge. This cannot be avoided, due to two reasons;
The turbochargers adiabatic efficiency. You'll notice on turbo compressor maps how they have comp. efficiency islands, with an eficiency rating next to them. That means, that for every unit of energy consumed by the turbocharger, the number stated by the island will be used to compress air. The rest of the energy is lost, mainly as heat going into the intake charge.
The second reason is that you'll generate heat by compressing air, since youre forcing more air to be inside a particular amount of space..
The intercooler removes much of this heat.. BUT its only effective if the car is going at a ffair amount of speed. Otherwise, the intercooler becomes heat soaked, and is only adding to throttle lag. Thats why water/methanol injection is superior to intercooling IMO
