When building a high-performance engine capable of producing over 600 horsepower, selecting the right wastegate is crucial. The wastegate plays a significant role in managing boost pressure, ensuring that the engine operates efficiently and reliably. In this article, we will compare the best wastegate sizes from two leading manufacturers: BorgWarner and HKS.
Understanding Wastegates
A wastegate is a valve that regulates the flow of exhaust gases to the turbocharger. It prevents the turbo from producing too much boost, which can lead to engine damage. There are two main types of wastegates: internal and external. For high horsepower applications, external wastegates are often preferred due to their ability to handle higher flow rates and provide better boost control.
Factors to Consider When Choosing a Wastegate
- Boost levels: The amount of boost you plan to run significantly impacts the size of the wastegate needed.
- Engine configuration: Different engine setups may require different wastegate sizes for optimal performance.
- Turbocharger size: The size of your turbocharger can influence the wastegate choice, as larger turbos may need larger wastegates to control boost effectively.
- Material and construction: The durability and heat resistance of the wastegate materials are important for longevity in high-performance applications.
BorgWarner Wastegates
BorgWarner is known for its high-quality turbochargers and wastegates. Their wastegates are designed to provide precise boost control and are available in various sizes. For 600+ hp builds, the following models are popular:
- BorgWarner wastegate 44mm: Suitable for moderate boost levels, this model provides excellent response and control.
- BorgWarner wastegate 50mm: Ideal for higher power applications, offering enhanced flow and boost control.
- BorgWarner wastegate 60mm: Designed for extreme performance, this size is perfect for builds exceeding 600 hp.
HKS Wastegates
HKS is another reputable brand in the performance automotive industry, known for its innovative designs and high-performance parts. Their wastegates are engineered for reliability and performance. For builds exceeding 600 hp, consider the following HKS models:
- HKS wastegate 40mm: A smaller option suitable for lower boost levels, providing good control for moderate builds.
- HKS wastegate 50mm: This model offers a balance between size and performance, suitable for many 600 hp applications.
- HKS wastegate 60mm: The best choice for high horsepower builds, offering superior flow and control.
Comparison of BorgWarner and HKS Wastegates
When comparing BorgWarner and HKS wastegates, several factors come into play:
- Size Options: Both brands offer a range of sizes, but BorgWarner tends to have a broader selection for extreme builds.
- Build Quality: Both brands are known for their high-quality materials, but HKS may have an edge in innovative designs.
- Boost Control: BorgWarner wastegates are often praised for their precise boost control in high-performance applications.
- Price: HKS wastegates may be priced slightly higher due to their brand reputation and engineering.
Conclusion
Choosing the right wastegate for a 600+ hp build is essential for achieving optimal performance and reliability. Both BorgWarner and HKS offer excellent options, with various sizes and features to suit different engine configurations. Ultimately, the best choice will depend on your specific build requirements, budget, and personal preferences. By considering the factors outlined in this article, you can make an informed decision and ensure your high-performance engine runs smoothly and efficiently.
