The electric turbo supercharger is a game-changer for car enthusiasts and environmentally conscious drivers alike. It's a technology that combines the efficiency of electric motors with the power boost of traditional turbochargers.
An electric turbo supercharger can increase engine power by up to 100 horsepower, making it a great option for those looking to upgrade their vehicle's performance. This boost in power also comes with improved fuel efficiency, thanks to the electric motor's ability to provide instant torque.
The electric motor used in these systems is typically powered by the vehicle's battery, which means it can be more efficient than traditional turbochargers that rely on exhaust gases. This results in less energy wasted and more power available for the engine.
What is an Electric Turbo Supercharger?
An electric turbo supercharger is a game-changer in the world of high-performance engines. It's essentially a turbocharger with an integrated electric motor that eliminates turbo lag and provides instant torque.
The electric motor is slim, measuring about 1.6 inches, and is integrated directly on the turbocharger shaft. This allows for a significant improvement in response time, even from idle speed.
The electric turbocharger can achieve speeds of up to 170,000 rpm, enabling a very high rate of air flow. This means that the engine can breathe more easily and respond more quickly to driver input.
The electrification of the turbocharger also enables higher torque at low engine speeds, which enhances agility and optimizes acceleration capability from a standstill.

Advantages of Turbochargers
Electric turbochargers offer a range of benefits that make them an attractive option for car enthusiasts. They eliminate turbo lag by providing a constant air input once warmed up.
Unlike superchargers, electric turbos don't reduce engine power while in use, allowing for a smoother and more consistent driving experience. They also provide the same level of torque throughout the engine's RPM range.
Electric turbos can be switched off when not needed, such as during long drives at a constant speed, allowing the engine to function at a higher efficiency and saving fuel in the long run. This makes them a great option for commuters or road trippers.
By not sapping engine power to remain active, electric turbos can increase the power gained from activating the device, making them a more efficient choice. They also take up significantly less space than traditional turbo-supercharger systems.
Overall, electric turbos are a great option for those looking to boost their car's performance without sacrificing power or efficiency.
Garrett's Technology
Garrett's E-Turbo is a game-changer in the world of turbocharging.
Unlike traditional systems, Garrett's E-Turbo harnesses an electric motor to propel the compressor, ensuring optimized engine efficiency and performance across all RPMs.
The E-Turbo is made up of an electric motor, compressor, turbine, and advanced power electronics, working together in harmony to deliver a seamless air supply to the combustion chamber.

This innovative approach enables higher power ratings for engines by de-constraining turbo design from low engine speed requirements.
The result is an architecture that enables the turbine to be sized to deliver performance without compromise at high speed.
The onboard electric motor provides instantaneous boost via the compressor at lower engine speed, where there is less available exhaust gas energy.
Understanding Turbochargers
An electric turbocharger, also known as an E-turbo, is a type of turbocharger that uses a combination of exhaust gases and an electric motor to generate boost.
The E-turbo's basic functionality is similar to a standard turbocharger, but it also includes an electric motor that powers a compressor to provide instant air pressure, eliminating lag.
This instant air pressure is crucial for immediate response and is made possible by the electric motor, which is powered by the car's battery.
The E-turbo's compressor forces more air into the combustion chamber, significantly boosting engine power, and the turbine uses the exhaust gas to deliver boost, just like a regular turbo.

Here's a breakdown of the E-turbo's components:
- Electric Motor: Powers the compressor to provide instant air pressure, ensuring immediate response and eliminating lag.
- Compressor: Forces more air into the combustion chamber, significantly boosting engine power.
- Turbine: Uses the exhaust gas to deliver boost, just like a regular turbo, and recuperates energy at high engine RPM
- Power Electronics: Controls the electric motor, guaranteeing the E-Turbo operates at peak efficiency.
Turbocharger Basics
A turbocharger is a type of engine component that uses the energy of exhaust gases to compress air, which is then forced into the engine's combustion chamber. This results in a significant boost in engine power.
The basic functionality of a turbocharger is to use hot exhaust gases to power a turbine, which in turn drives a compressor that forces more air into the combustion chamber.
Turbochargers are designed to eliminate the delay in power delivery that can occur with superchargers. They work by using the exhaust gases to power the turbine, which then drives the compressor.

Disadvantages of Turbochargers
Electric turbochargers are still a relatively new technology, and as such, they're not without their drawbacks. One of the main disadvantages is that they can actually increase fuel consumption and emissions, although not as much as a conventional turbo- or supercharger.
The primary purpose of electric turbochargers is to boost a vehicle's performance, not to reduce fuel consumption or emissions. This means they might not be the best choice for environmentally conscious drivers.
Given their status as emerging technology, electric turbochargers are likely to remain more expensive than traditional turbochargers for some time. The cost is just one factor to consider when weighing the pros and cons of electric turbocharging.
The reliability of electric turbochargers is largely untested, with limited data available due to their limited application. This lack of data makes it difficult to make a definitive judgment about their long-term durability.
As the world shifts towards electric cars, turbochargers may become increasingly unnecessary. With the writing on the wall for fossil fuels and internal combustion engines, electric turbochargers might become a relic of the past.
So, What's the Catch?
The benefits of an electric turbocharger are undeniable, but like any technology, it's not without its drawbacks. The main catch is the size of the power supply, which is essentially a big battery box that needs to be stowed away in your car.
One of the limitations of an electric turbocharger is its power supply, which can only run the turbo for a total of 4 minutes when fully charged. This means you'll need to recharge the battery frequently to maintain boost.
The recharge time is also a consideration, as it takes 10 seconds to recharge for every 1 second of boost time. This adds up to 40 minutes of driving without boost for a full charge, which may not be ideal for some drivers.
However, I think this limitation is manageable for daily driving, especially if you're not a track enthusiast. The power comes on with a push of a button and then you switch it off, and the power supply goes back into charging mode. It's almost like a button-controlled nitrous system, where you activate it when you need it and then shut it off when you don't.
In fact, this system could be ideal for drag racing, where you only need boost for short bursts of time. With a 4-minute power supply, you could potentially get 16 drag races out of it, which is a pretty sweet deal.
Frequently Asked Questions
Can you have a turbo with a supercharger?
Yes, it's possible to combine a turbocharger with a supercharger in a powertrain, known as twincharging, which can deliver both low-end performance and high-RPM boost. This emerging technology is designed to optimize performance and efficiency in smaller engines.
