Another name for "intercooler" and a more proper one is "Intake Charge Cooler"... It's purpose is to cool the charge of air coming into the engine thus allowing more air to be packed into the cylinder making a more oxygen dense "air charge" for combustion.[cold air is more dense, rule of physics]
If you want to make more power with a diesel... add more air... simple but true. [Ok.. eventually more fuel also.. but to a point] Finding the balance of how much cooling, how much air flow, tubing size, available energy from extraction of the exhaust flow, etc etc etc.. has kept engineers employed and sent children through college for years. It is a fine art, supported by fine engineering, and a little luck [some days]. I'm sure the hood "scope" mounted device was only done after all those considerations were weighed properly... right???
