The Subaru BRZ is a popular sports car known for its lightweight design and agile handling. However, many enthusiasts seek to enhance its performance significantly. One of the most effective ways to achieve this is through the installation of a supercharger. This article explores the power gains achievable by equipping a Subaru BRZ with a Whipple supercharger, taking the stock horsepower from 200 HP to over 300 HP.
Understanding the Subaru BRZ and Its Stock Performance
The Subaru BRZ, along with its twin the Toyota 86, is powered by a naturally aspirated 2.4-liter flat-four engine. This engine produces a respectable 200 horsepower and 151 lb-ft of torque. While this power output is sufficient for many drivers, performance enthusiasts often desire more power for track days and spirited driving.
Why Choose a Whipple Supercharger?
Whipple superchargers are renowned for their quality and performance. They utilize a twin-screw design that provides a significant boost in power while maintaining reliability. Here are some reasons to consider a Whipple supercharger for your BRZ:
- Increased Power Output: Whipple superchargers can boost horsepower significantly, often exceeding 300 HP.
- Improved Throttle Response: The supercharger provides instant power delivery, enhancing the driving experience.
- Reliability: Whipple is known for producing durable systems that can withstand the rigors of performance driving.
Installation Process of the Whipple Supercharger
Installing a Whipple supercharger on a Subaru BRZ requires careful planning and execution. Here’s a general overview of the installation process:
- Preparation: Gather all necessary tools and components, including the supercharger kit, gaskets, and fluids.
- Remove Existing Components: Take off the intake manifold, air intake, and any other components obstructing access to the engine.
- Install the Supercharger: Follow the manufacturer’s instructions to mount the supercharger onto the engine.
- Reassemble: Replace the intake manifold and other components, ensuring all connections are secure.
- Tuning: After installation, a proper tune is essential to optimize engine performance and ensure reliability.
Expected Power Gains with Whipple Supercharger
After installing a Whipple supercharger, drivers can expect substantial power gains. Here’s a breakdown of the expected performance metrics:
- Horsepower: Stock BRZ produces approximately 200 HP; with the Whipple supercharger, this can rise to over 300 HP.
- Torque: Torque output can also see significant increases, often exceeding 250 lb-ft, enhancing acceleration.
- Performance Metrics: Improved 0-60 mph times and quarter-mile performance are common after supercharging.
Additional Modifications to Consider
To fully benefit from the power gains provided by the Whipple supercharger, consider these additional modifications:
- Upgraded Fuel System: A higher flow fuel pump and injectors may be necessary to supply the increased fuel demands.
- Performance Exhaust: An aftermarket exhaust system can help reduce back pressure and improve sound.
- Cooling Upgrades: An upgraded intercooler can help manage the increased heat generated by the supercharger.
Conclusion
Upgrading a Subaru BRZ with a Whipple supercharger is an excellent way to enhance its performance, transforming it from a 200 HP stock vehicle to a powerful machine exceeding 300 HP. With the right installation and tuning, drivers can experience thrilling acceleration and improved overall driving dynamics. For enthusiasts looking to take their BRZ to the next level, a Whipple supercharger is a highly recommended modification.
