Totally stupid question/way turbocharger

People I have a very stupid question. I have no idea about truck engines at all. One thing interests me. There are LWKs I can find Scania who have a FETTEN V8 This engine with several liters of engine capacity! Do they even have a turbocharger?? Actually, there are no more diesel vehicles without turbochargers but now I don’t know… If the truck has a 10liter large v8 engine it has enough steam even without turbo or?
