How do electric turbochargers work

E-power for everyone: electric turbocharger / compressor

Reading time about 5 minutes

Electric turbochargers or electric compressors are available as universal devices that can be used with most cars without any problems. It doesn't matter whether it is a gasoline or diesel engine. An e-turbocharger can be used with injectors or carburetors, with turbo or naturally aspirated engines. Provided that the correct models are used. Electric turbochargers can be seen as a further development of the often ridiculed power booster. Various electrical intake air compressors are commercially available. More than a thousand systems are known. What are the advantages of electric turbochargers / compressors and where are they used? These and other questions are answered below.

More air performance thanks to the e-turbocharger

The electric turbocharger offers you as a tuning enthusiast some advantages. The right e-turbocharger, compressor system leads to a partially better torque in the lower speed range and enables faster throttle response. An air output of approximately 15,000 liters per minute to the intake air can be achieved. The intake air is compressed by a slight dynamic pressure. E-turbochargers can, depending on the system, also develop up to approx. 20 hp in the medium and lower speed range. An electric turbocharger should be able to deliver significantly more air with the throttle valve in the same position. For example, a dynamic pressure of approximately 1.45 PSI or 0.1 bar can be generated while driving. At least that's what the providers promise! Electric turbochargers / compressors should, however, be installed exactly according to the instructions in order to achieve the desired performance.

Advantages of e-turbos / e-compressors

Electric turbochargers / compressors can ensure better cooling of the intake air. Cooling the air is beneficial because cold air is richer in oxygen than warm air and burns better. An electric turbocharger can provide better combustion, and in some cases even provides a reduction in exhaust gas. The consumption of the vehicle can be reduced by around 10 percent with the right electric turbocharger / compressor. At least that's what the providers promise! However, the economy or the reduction in consumption also depends on the driving style of the driver and the type of vehicle. Electric turbochargers / compressors are commercially available with patented systems that are described as not subject to registration. If in doubt, the TÜV should be asked about the registration requirement before installation. Professional tuning workshops can also help with the subject of mandatory registration. Good electric turbochargers / compressors deliver power where it is needed.

Universal turbocharger

Universal turbochargers are available on the market, which are more or less a further development of the power booster. The products should always provide air and already deliver power in the lower and medium speed range. The turbocharger should lead to a smooth, powerful and agile running behavior of the engine. When buying an electric turbocharger, attention should be paid to its suitability for the respective vehicle model. Universal turbochargers that are suitable for many diesel and gasoline cars are available on the market. Turbochargers can be used in front of the air flow meter or the air filter box (series filter box for VW and Turbo VR6 engines, etc.). However, you should find out beforehand what intake air the engine consumes at maximum speed without the turbocharger. The maximum value of the e-system must therefore be higher, otherwise the turbo / compressor will even be a disadvantage. You should also keep in mind that the software must of course be informed that more intake air is available from now on. Another important criterion is the best possible quality. After all, this part is sometimes located directly in front of the intake "after the air filter" and if it dissolves into air, the splinters drawn in can even lead to engine damage.

better ask the tuner of trust

If the electric impeller system brings any understandable benefit at all, then it should probably be in the speed range up to a maximum of 2500 rpm. move. The extent to which this system may even become an obstacle above this speed can only be determined on a dynamometer. We hope that you liked the info report on the term electric turbocharger / compressor from the field of autotuning.
