The R8 twin turbo kit has become a popular upgrade for those seeking to enhance their vehicle’s performance. Among the various options available, the choice between 86mm and 88mm turbos is a critical decision that can significantly influence power potential and driving experience.
Understanding Turbo Sizes
Turbochargers are measured by their compressor wheel diameter, which directly affects their airflow capacity. The two common sizes for the R8 twin turbo kit are 86mm and 88mm. Each size offers distinct advantages and disadvantages, making it essential to understand their implications for performance.
86mm Turbos
The 86mm turbo option is often favored for its balance between responsiveness and power. Here are some key points about this size:
- Boost Response: The smaller size typically allows for quicker spool times, which means faster throttle response.
- Power Band: Ideal for those who want a broad power band suitable for street driving.
- Heat Management: Produces less heat compared to larger turbos, which can be beneficial for engine longevity.
- Installation: Generally easier to install due to compact size and compatibility with existing components.
88mm Turbos
The 88mm turbos are designed for those seeking maximum power potential. Here’s what you need to know:
- Power Output: Capable of producing significantly higher horsepower, making them suitable for track or high-performance applications.
- Spool Time: May have a slightly delayed spool time compared to 86mm turbos, which could affect low-end power delivery.
- Heat Generation: Larger turbos may produce more heat, necessitating enhanced cooling solutions.
- Upgrades: Often requires additional upgrades to the fuel system and engine internals to handle increased power.
Power Potential Comparison
When considering power potential, both turbo sizes have their merits, but the choice ultimately depends on the intended use of the vehicle. Below is a comparison of the expected power outputs for each turbo size.
- 86mm Turbos: Typically capable of producing around 600-800 horsepower, depending on supporting modifications.
- 88mm Turbos: Can reach upwards of 800-1000 horsepower, especially with proper tuning and supporting upgrades.
Factors to Consider When Choosing Turbo Size
Choosing between 86mm and 88mm turbos involves several considerations that can impact overall performance and drivability.
- Driving Style: Consider whether the vehicle will be used primarily for street driving or track racing.
- Engine Setup: Evaluate the current engine setup and whether it can handle the increased power from larger turbos.
- Budget: Factor in the cost of not only the turbos but also any necessary supporting modifications.
- Future Plans: Think about future performance goals and whether you plan to upgrade other components.
Conclusion
Ultimately, the decision between 86mm and 88mm turbos for the R8 twin turbo kit should be based on individual performance goals and driving preferences. Each size offers unique benefits, making it essential to weigh the options carefully before making a purchase.
