Re: Turbo diesels

If a turbo packs up you will have a decrease in air into the cylinders, a richer mixture because there won't be forced (turbo) driven air getting in. But the engine will still take air in naturally. A blown turbo will not hinder the exhaust as it is a turbine. The engine will still run, at reduced power of course, and smoke like a hippie. The smoke was the first indication you'd blown a turbo on the big sportfish boats. A dead giveaway. It happened fairly regularly. We carried spares, and with as much a a million bucks on the line in a tournament, our budget was somewhat greater than most sailors.
If you wanted to remove your turbo permanently, you would require different injectors at the very least. Possibly new pistons, rods and rings as well, and then you'd have to mess with timing. PITA.
