Baby Killer 

An unusually large and often upgraded turbocharger found on diesel trucks, 8 second drag cars, and such. The name stmes from the fact that if a small child were to walk by while the turbo was spooled up, in theory the kid would be sucked in and run through the engine.

Dang that Dodge Cummins diesel has a baby killer turbo on it.
