THAT IS FING CRAZY ahaha he just bliped the throttle and lifted the front tire and blew the head gaskets that is sooooo funny

So that is the **** I get to play with on a daily basis now..... I love my new job, lol.

It'* unusual, but they are out there. They aren't used in anything that would be driven on the road because supercharged diesels have a very small operating RPM range. They would mainly be used for things like pumps, generators, and industrial applications that require tons of torque at a constant operating RPM. Locomotives fall into tht category, because the diesel motor is only used to generate electricity, which powers electric motor that drive the wheels. They only have about a 500 RPM operating range.

A turbo varies boost by engine exhaust pressure. The more fuel/air used, the more boost there is. This means you can basically run a turbo diesel to any reasonable RPM and it will make the perfect boost for that RPM range and fuel/air mix.
An */C, however, varies boost by engine speed,so it will only make the exact right boost at a certain RPM and fall off sharply either side of the power peak. So basically, you design a */Ced diesel for a specific operating speed, and that'* all it does.

These engines will top out at 1,000rpm. Usually they never hit over 950 rpm. Plus once they are started, they will run 24/7 until they need maintenance.
