Many 4 cylinder gas cars now use turbos that can run many hours at a time hiway driving.
True most industrial diesel turbos may only spin 50,000-70,000 RPM while gas may go over 100,000. But the turbos they put on the small diesels like VWs can easily put out over 150 hp from 2 liters and those turbos see EGT teperatures much more like those from a gas engine, they also have variable geometry so so have spool up measured in fractions of a second.
I have 2 turbo diesel cars in the yard with a total of over half a million kilometers on them done nothing more than ajust the waste gate. Before that I had a gas turbo volvo which went over 400,000 with one rebuilt turbo.
