Turbochargers: How it works | Pros & Cons | Types

How Turbocharger Works?

Here are some Pros and Cons of Turbochargers :

Advantages of Turbochargers:

1. Efficiency: Turbochargers are more efficient than superchargers because they are powered by exhaust gases that would otherwise be wasted. This results in better fuel economy and performance.
2. Cost: Turbochargers tend to be less expensive than superchargers, both in terms of initial cost and maintenance.
3. Low lag time: Turbochargers often have a small amount of lag time before they begin to provide increased boost. This results in more immediate power and better performance.
4. Size and weight: Turbochargers tend to be smaller and lighter than superchargers, which is an advantage for vehicles where space is limited.

Disadvantages of Turbochargers:

1. Heat: Turbochargers generate a lot of heat, which can cause issues with engine components and reduce performance.
2. Durability: Turbochargers are complex devices and can be prone to failure if not maintained properly.
3. Complexity: Turbochargers are more complex than superchargers and require more expertise to install and maintain.
4. Not suitable for high-performance vehicles: Turbochargers may not be suitable for high-performance vehicles that require a lot of power and instant boost.

Types of Turbochagers

There are several types of turbochargers available, each with their own unique characteristics and advantages. The most common types of turbochargers include:

1.Single-turbo: A single-turbo system uses one turbocharger to increase the amount of air entering the engine. This is the most common type of turbocharger and is suitable for most vehicles.

Single Turbochagers are popular in passenger cars, Sports cars,Trucks , SUVs and in heavy duty trucks & buses. Most common and primarly used to boost high level of power and performance.

2.Twin-turbo: A twin-turbo system uses two turbochargers, one for each bank of cylinders. This system provides more power than a single-turbo system, but it is also more complex and expensive.

Twin-Turbochargers are popular in high performance cars such as sports cars, super cards, Luxury cars (high-end sedans, coupes, and SUVs,), Racing cars (touring cars, sportscars and prototype) and also in heavy duty commercial vehicles. Primarly used to boost ultimate power and performance more than single-turbo.

3.Sequential-turbo: A sequential-turbo system uses two turbochargers that work together to increase the amount of air entering the engine. This system provides more power than a single-turbo system and has less lag time than a twin-turbo system.

This is less common type of forced induction system, it is typically used in high-performance and racing applications which included Racing cars, High performance cars and heavy duty vehicles.

4.Variable Geometry Turbocharger (VGT): A VGT system uses a turbine housing with adjustable vanes, which can be adjusted to optimize the turbine’s performance at different engine speeds. This results in better low-end and high-end performance.

It is basically more advanced type of turbocharging system that can adjust the angle of the turbine vanes to optimize the turbine’s performance at different engine speeds. Primarly used in passengers cars, Trucks & SUVs , Diesel engine and commercial vehicles.

5.Electric Turbochargers: An electric turbocharger uses an electric motor to spin the turbine, instead of exhaust gases. This results in instant boost, no lag time and better performance.

Electric Turbochagers are popular in electric cars, Hybrid cards and internal combustion engines.

It’s important to note that the best type of turbocharger for your vehicle will depend on your specific needs and the type of vehicle you have. It’s always recommended to consult with a mechanic or a professional before making any decision.

Superchargers: How it works Pros & Cons | Types

A supercharger is a type of forced induction system that increases the amount of air entering the engine, allowing it to burn more fuel and produce more power. Unlike a turbocharger, which is powered by exhaust gases, a supercharger is driven by a belt connected to the engine’s crankshaft.

Here are some Pros and Cons of Superchargers

Advantages of Superchargers:

1. Instant Boost: Superchargers provide instant boost which is essential for heavy loads and towing.
2. Reliability: Superchargers are generally more reliable than turbochargers, as they have fewer moving parts and are less complex.
3. Power: Superchargers provide more power than a naturally aspirated engine.
4. Compatibility: Superchargers are more compatible with older vehicles and are easy to install.

Disadvantages of Superchargers:

1. Efficiency: Superchargers consume power directly from the engine which can decrease the overall fuel efficiency of the vehicle.
2. Cost: Superchargers tend to be more expensive than turbochargers, both in terms of initial cost and maintenance.
3. Size and weight: Superchargers are generally larger and heavier than turbochargers, which can be an issue for vehicles where space is limited.
4. Heat: Superchargers generate a lot of heat, which can cause issues with engine components and reduce performance.
5. Not suitable for fuel-efficient vehicles: Superchargers may not be suitable for fuel-efficient vehicles that prioritize fuel economy over performance.

Types of Superchargers And Which one to choose

There are several types of superchargers available, each with their own unique characteristics and advantages. The most common types of superchargers include:

1.Roots supercharger: A Roots supercharger is a positive displacement supercharger that uses two counter-rotating rotors to compress the air entering the engine. This type of supercharger is commonly found on older muscle cars and hot rods.

They are positive displacement superchargers which means that they pump a fixed amount of air per revolution.Roots Supercharger are popular in Classic cars , muscle cars, high performance cars and commercial vehicles. 

2.Centrifugal supercharger: A centrifugal supercharger is a dynamic compressor that uses a centrifugal impeller to compress the air entering the engine. This type of supercharger is more efficient than a Roots supercharger and is commonly found on newer high-performance vehicles.

Centrifugal superchargers are less common than other types of superchargers and are typically found in high-performance and racing applications such as High performance cars (sports cars and supercars), Racing cars (touring cars, sportscars, and prototypes) , Classic and Retrofitted cars and kit cars.

3.Twin-screw supercharger: A twin-screw supercharger is a positive displacement supercharger that uses two meshing helical screws to compress the air entering the engine. This type of supercharger is known for its high efficiency and low noise level.

Similar to centrifugal supercharger, Twin screw superchargers are less common than other types of superchargers and are typically found in high-performance and racing applications such as High performance cars (sports cars and supercars), Racing cars (touring cars, sportscars, and prototypes) , Classic and Retrofitted cars and kit cars.

4.Lysholm supercharger: A Lysholm supercharger is similar to a twin-screw supercharger, but it uses a unique design that allows for more efficient compression of the air entering the engine.

5.Electric Superchargers: Electric superchargers use an electric motor to spin the compressor, instead of the engine’s power. They are known for their instant boost and low lag time.

Electric Superchargers are popular in Electric and hybrid cars.

It’s important to note that the best type of supercharger for your vehicle will depend on your specific needs and the type of vehicle you have. It’s always recommended to consult with a mechanic or a professional before making any decision.
