Key Components of a Turbo Kit

So, what's actually inside a turbo kit? Here's a rundown of the essential parts:

• Turbocharger: This is the heart of the kit. It's a turbine that's spun by exhaust gases, which in turn compresses the incoming air. There are different sizes and types of turbos, each with its own characteristics in terms of power delivery and responsiveness. A larger turbo will generally produce more power at higher RPMs but may suffer from more turbo lag (the delay between pressing the accelerator and feeling the boost). A smaller turbo will spool up quicker, providing better low-end response but may not deliver as much peak power. Choosing the right turbo for your needs is crucial, and it's something you should discuss with your tuner. Factors to consider include your driving style, your power goals, and the overall setup of your car.
• Intercooler: Compressing air creates heat, which reduces its density and effectiveness. An intercooler cools the compressed air before it enters the engine, maximizing power output. The intercooler acts as a radiator for the compressed air, dissipating heat and increasing its density. This results in a more efficient combustion process and ultimately, more power. There are two main types of intercoolers: air-to-air and air-to-water. Air-to-air intercoolers are simpler and more common, while air-to-water intercoolers are more efficient but also more complex and expensive. The choice between the two depends on your specific needs and the overall design of your turbo kit. A well-designed intercooler is essential for extracting the maximum performance from your turbo kit and ensuring that your engine runs safely and reliably.
• Piping: This is the network of tubes that carries the compressed air from the turbo to the intercooler and then to the engine. The piping needs to be strong and well-sealed to prevent leaks and ensure optimal airflow. The material used for the piping is also important, with aluminum and stainless steel being the most common choices. Aluminum is lightweight and offers good heat dissipation, while stainless steel is more durable and resistant to corrosion. The diameter of the piping is also crucial, as it needs to be sized appropriately to match the flow characteristics of the turbo and the engine. Too small of a diameter can restrict airflow and limit power, while too large of a diameter can reduce boost response. Proper installation of the piping is essential to prevent leaks and ensure that the turbo kit performs as intended.
• Wastegate: This valve controls the amount of exhaust gas that bypasses the turbo, regulating the boost pressure. Without a wastegate, the turbo would continue to spin faster and faster, eventually leading to overboost and potential engine damage. The wastegate is typically controlled by a solenoid or a boost controller, which allows you to adjust the boost pressure to your desired level. Some turbo kits come with internal wastegates, which are integrated into the turbo housing, while others use external wastegates, which are mounted separately. External wastegates generally offer better control and flow capacity, but they are also more expensive and require more complex plumbing. A properly functioning wastegate is essential for maintaining safe and reliable boost levels and preventing engine damage.
• Blow-Off Valve (BOV) or Diverter Valve: When you release the throttle, the turbo is still spinning, creating pressure. A BOV or diverter valve releases this pressure to prevent damage to the turbo and improve throttle response. A BOV vents the excess pressure to the atmosphere, creating a distinctive whooshing sound, while a diverter valve recirculates the pressure back into the intake system. The choice between the two is largely a matter of personal preference, although some cars may respond better to one or the other. A BOV can be more prone to causing issues with the car's mass airflow sensor, while a diverter valve may not provide as much of a performance benefit. Regardless of which type you choose, a properly functioning BOV or diverter valve is essential for protecting your turbo and ensuring optimal throttle response.
• Fuel Injectors & Fuel Pump: More air means you need more fuel. Upgraded fuel injectors and a higher-flowing fuel pump are often necessary to keep up with the increased demand. The stock fuel injectors and fuel pump may not be able to deliver enough fuel to support the increased airflow from the turbo, leading to a lean condition that can damage the engine. Upgraded fuel injectors and a fuel pump are designed to provide the necessary fuel flow to maintain a safe and optimal air-fuel ratio. The size and capacity of the fuel injectors and fuel pump will depend on the size of the turbo and the amount of power you're aiming to make. It's important to choose components that are properly matched to your setup to ensure reliable and consistent performance. A fuel pressure regulator may also be necessary to maintain consistent fuel pressure under varying boost conditions.
• Engine Management System (ECU Tuning): This is where the magic happens. The ECU needs to be recalibrated to properly manage the increased airflow and fuel delivery. Tuning can be done with a standalone ECU or by reflashing the stock ECU with custom software. Tuning is arguably the most important aspect of adding a turbo kit. Without proper tuning, the engine will not be able to take advantage of the increased airflow and fuel, and it could even be damaged. Tuning involves adjusting various parameters in the ECU, such as fuel maps, ignition timing, and boost control, to optimize performance and ensure that the engine is running safely. A good tuner will be able to tailor the tune to your specific setup and driving style. Tuning can be done on a dyno, which allows the tuner to monitor the engine's performance in real-time and make adjustments as needed. It's important to choose a tuner who has experience with the 2017 Golf R and who is familiar with the specific turbo kit that you're using.

Choosing the Right Turbo Kit for Your Golf R
