Stocked turbo

Types of Stocked Turbo

A turbocharger, also known as a turbo, is a forced induction device that increases the power output of an internal combustion engine. Stock turbos are factory-installed by the manufacturer. They are often designed to meet specific requirements or performance levels while maintaining reliability and durability. The following are types of stocked turbo:

• Single-Turbo Setup

  A single-stock turbo uses one turbocharger in its setup. It is the most common type of turbo setup found in many vehicles. Single turbos are designed to offer a balance between performance and efficiency. They are also simple in design and easy to maintain. Single-turbo setups can also generate significant power gains. The power output depends on the size and design of the turbocharger. There are different types of single-stock turbos. They include:

  • Variable Geometry Turbocharger (VGT)

    A variable geometry turbocharger (VGT) is designed to optimize performance across a wider range of engine speeds. It does this by adjusting the geometry of the turbine blades. VGT stock turbos minimize turbo lag and improve efficiency.

  • Variable Twin Scroll Turbocharger (VTS)

    A variable twin-scroll turbocharger (VTS) is designed to work with a twin-scroll manifold. It uses one variable geometry turbocharger. The VTS turbo improves engine response and reduces turbo lag. It also provides high torque and power output.

  • Electric Turbo Compound (ETC)

    An electric turbo compound (ETC) uses an electric motor to drive the compressor. The ETC stock turbo improves the efficiency of the turbocharger. It also reduces turbo lag and boosts power output.

• Twin-Turbo Setup

  Some high-performance vehicles come with a twin-stock turbo setup. The twin-turbo setup uses two turbochargers. The twin-turbo setup is further divided into two categories. They include parallel and sequential twin-turbo setups.

  • Parallel Twin-Turbo Setup

    Parallel twin-stock turbo setups use two identical turbochargers. Each turbocharger is connected to one bank of a V6 or V8 engine. The parallel twin-turbo design improves engine efficiency. It also increases power output without adding extra weight.

  • Sequential Twin-Turbo Setup

    In a sequential twin-stock turbo setup, two turbochargers of different sizes are used. The smaller turbocharger is activated at low engine speeds. While the larger turbocharger activates at higher engine speeds. The sequential twin-turbo setup provides a broad power band and reduces turbo lag.

Specification and maintenance of stocked turbo

The specifications of a turbocharged engine can vary based on the type of turbo and the make and model of the vehicle. Here are some general specifications:

• Size

  Stock turbos are generally smaller than aftermarket turbos. They measure between 50 and 60 mm. The size of the turbine determines how much air it can move and the amount of boost it can create.

• Compressor wheel

  The compressor wheel draws in air and forces it into the engine. It is measured in pounds per minute (lb/min) or grams per second (g/s). Stock turbos have a compressor wheel that flows between 40 and 50 lb/min (or 60 to 85 g/s).

• Turbine wheel

  The turbine wheel is spun by exhaust gases and powers the turbo. It is measured in trim or mm. Stock turbos have a turbine wheel trim that ranges from 70 to 80, and those that are measured in mm have a size between 60 and 70 mm.

• Boost pressure

  Boost pressure is the amount of pressure the turbo creates in the intake manifold. It's measured in pounds per square inch (PSI) or bar. Stock turbos have a boost pressure range of 6 to 12 PSI (0.4 to 0.8 bar).

• Wastegate

  A wastegate regulates the amount of boost the turbo generates. It is measured in millimeters (mm) or pounds (lbs). Stock turbos come with a wastegate that measures between 25 and 40 mm or 10 to 15 lbs.

Maintenance of stocked turbo is important to ensure optimal performance and avoid expensive damage. Here are some maintenance tips:

• Regular oil changes: Follow the recommended oil change schedule to keep the engine lubricated. Clean oil ensures proper lubrication of the turbo components, reducing friction and wear. Use high-quality oil as recommended by the vehicle manufacturer.
• Cool down: Allow the turbo to cool before turning off the engine, especially after hard driving. This prevents turbo timer heat buildup and protects the bearings. id heat shield also reduces heat transfer to nearby components.
• Air filter maintenance: Inspect and replace the air filter regularly. A clean air filter ensures proper airflow to the turbo, maintaining boost pressure and engine performance. Consider upgrading to a high-flow air filter for improved performance.
• Check for leaks: Inspect the turbo and associated piping for oil or boost leaks. Leaks can reduce turbo performance and lead to engine damage. Address any leaks immediately and ensure all connections are secure.
• Turbo cleaning: Consider using a turbo cleaning kit or having a professional clean the turbo. Over time, carbon deposits can build up and affect performance. Cleaning removes these deposits and restores optimal turbo function.

How to choose stocked turbo

Choosing the right turbo to stock requires understanding the customer's needs and considering various factors.

• Understanding the needs

  What does the client use the car for? For day-to-day commuting, occasional towing, off-road use, or track performance? Understanding the use will help decide how much power the engine needs to have.

• Engine size

  Consider the type of engine the car has. Is it a small gas engine or a large diesel one? Larger engines can handle bigger turbos, while smaller ones work better with smaller turbos. For a petrol engine, a variable geometry turbo (VGT) is more suitable. It improves efficiency and performance.

• Car model and year

  Check what turbos work best with the specific car model and year. Some cars already have turbos, but they may need upgrading or replacing. Researching helps find the right turbo that matches the vehicle's specifications.

• Budget and cost

  Deciding how much to spend on a turbo is essential. There are many types with different price ranges. Remember, a more expensive turbo may give better performance but also needs more money for installation and other upgrades. So, consider the overall value.

• Brand and quality

  Look for well-known brands that make high-quality turbos. Reading reviews from other customers helps find a reliable turbo that works well and lasts long.

• Warranty and support

  A warranty is essential when choosing a turbo. It protects the investment in case something goes wrong. Also, good customer support from the turbo company helps with any questions or problems that may arise.

• Legal considerations

  Consider the emissions regulations and noise limits in the area. Some turbos may be too loud or produce too many emissions, which could be illegal. Choose a turbo that meets all the rules to avoid any trouble with the authorities.

Q and A

Q1: What are the advantages of using a stocked turbo?

A1: Stock turbos have several advantages. They are reliable because they are made by the car manufacturer. They also work well with the car's other parts. Stock turbos use less fuel and produce fewer emissions because they are designed to meet those standards. They are usually less expensive to maintain and repair. Finally, using a stock turbo keeps the car under warranty. Modifying the engine could void the warranty.

Q2: Can people upgrade their turbocharged engines without causing problems?

A2: Yes, upgrading the turbo is possible. However, it is essential to choose a turbo that is compatible with the engine and other parts of the car. Making a significant upgrade requires additional modifications and tuning to avoid causing problems. It is also important to consider the trade-off between increased power and reduced fuel efficiency.

Q3: Can a stocked turbo handle towing and hauling heavy loads?

A3: Stocked turbos can handle towing and hauling heavy loads. However, checking the vehicle's towing capacity and ensuring it is within the limits is essential. Overloading can cause damage to the engine, transmission, and other components. If towing or hauling is required frequently, considering a turbo with more power may be wise.

Q4: What is the maintenance required for stocked turbos?

A4: Maintaining a stocked turbo is essential to keep it running well. Change the oil and filter regularly to keep the engine clean. Let the turbo warm up before driving hard and cool down after to avoid damage. Keep the air filter clean, too, so the engine can breathe well. If there are any warning lights or sounds from the turbo, get it checked right away. Taking care of the turbo can help it last a long time and keep the car fast and fun to drive.
