The Subaru BRZ is known for its lightweight design and agile handling, but many enthusiasts seek to enhance its performance. One popular modification is the installation of a supercharger. In this article, we will explore how a 7psi supercharger kit can boost the output of a BRZ from 200 to 260 horsepower.
Understanding Supercharging
Supercharging is a method of forced induction that increases the engine’s air intake, allowing for more fuel to be burned and thus generating more power. Unlike turbochargers, which utilize exhaust gases to spin a turbine, superchargers are mechanically driven by the engine itself.
Benefits of Supercharging
There are several advantages to installing a supercharger on your BRZ:
- Increased horsepower and torque
- Improved throttle response
- Enhanced driving experience
- Potential for better fuel efficiency under certain conditions
The 7psi Supercharger Kit
A 7psi supercharger kit is designed to provide a significant boost in power without requiring extensive modifications to the engine. This level of boost is generally considered safe for the BRZ’s stock internals.
Components of the Kit
The typical 7psi supercharger kit includes the following components:
- Supercharger unit
- Intercooler
- Mounting brackets
- Belts and pulleys
- Fuel injectors
- Tuning software
Installation Process
Installing a supercharger kit requires mechanical knowledge and experience. Here are the basic steps involved in the installation process:
- Remove the engine cover and intake components.
- Install the supercharger unit and associated hardware.
- Connect the intercooler and plumbing.
- Upgrade the fuel injectors as needed.
- Reassemble the engine components and ensure all connections are secure.
- Upload the tuning software to optimize engine performance.
Power Gains Explained
With the installation of a 7psi supercharger, the BRZ’s power output can increase dramatically. Here’s how the gains are typically calculated:
- Stock horsepower: 200 hp
- Boost from supercharger: 60 hp
- Total output: 260 hp
Performance Metrics
In addition to horsepower gains, supercharging also affects other performance metrics:
- Torque increase: Typically, torque can rise from 151 lb-ft to around 190 lb-ft.
- Improved acceleration: The BRZ will experience faster 0-60 mph times.
- Enhanced top speed: A supercharged BRZ can achieve higher speeds on the track.
Considerations Before Installation
Before installing a supercharger kit, consider the following:
- Warranty implications: Check if the installation voids any existing warranties.
- Insurance coverage: Inform your insurance provider about the modifications.
- Maintenance requirements: Supercharged engines may require more frequent maintenance.
- Driving conditions: Consider how the added power will affect daily driving.
Conclusion
A 7psi supercharger kit can significantly enhance the performance of a Subaru BRZ, boosting horsepower from 200 to 260 hp. With proper installation and tuning, drivers can enjoy a more exhilarating driving experience while maintaining reliability. Always consult with professionals and do thorough research before proceeding with any modifications.
