A turbo engine is an internal combustion engine that uses a turbocharger, a forced induction device powered by the flow of exhaust gases, to compress the intake air and force more air into the engine to produce more power for a given displacement. The turbocharger is composed of a shaft with a turbine wheel on one end and a compressor wheel on the other, covered by a snail-shaped housing featuring an inlet port, which the wasted exhaust gases enter at a high pressure. As the air passes through the turbine, the turbine spins and the compressor turns with it, drawing in vast quantities of air which are compressed and passed out of the outlet port. A pipe feeds this compressed air back into the cylinders via an intercooler, which cools the air before it reaches the cylinders. Turbos run at high speeds, up to 250,000 RPM, so they typically have an oil cooling system to prevent overheating. The benefits of a turbo engine include extra power without sacrificing fuel efficiency, and improved performance and efficiency of the engine.
