The Scion FR-S is known for its lightweight design and sporty handling, but many enthusiasts seek more power to enhance their driving experience. Installing a Vortech supercharger is a popular modification that can significantly boost the performance of your FR-S. This article provides a comprehensive step-by-step guide to installing a Vortech supercharger, along with the expected power gains you can anticipate.
Understanding the Vortech Supercharger
A Vortech supercharger is a centrifugal supercharger that increases the engine’s air intake, allowing for more fuel to be burned and ultimately resulting in higher power output. The benefits of a Vortech supercharger include:
- Increased horsepower and torque
- Improved throttle response
- Enhanced driving experience
Tools and Materials Needed
Before starting the installation process, gather the necessary tools and materials:
- Vortech supercharger kit
- Socket set
- Wrenches
- Screwdrivers
- Torque wrench
- Vacuum hose
- Coolant
- Oil
- Gaskets and seals
Step-by-Step Installation Process
Step 1: Prepare Your Vehicle
Before beginning the installation, ensure your Scion FR-S is parked on a flat surface and the engine is cool. Disconnect the battery to prevent any electrical issues during the installation.
Step 2: Remove the Stock Intake System
Start by removing the stock intake system. This typically involves:
- Disconnecting the mass airflow sensor
- Removing the air filter and intake tube
- Unbolting the throttle body
Step 3: Install the Vortech Supercharger Bracket
Attach the Vortech supercharger bracket to the engine block using the provided hardware. Ensure that it is securely fastened and properly aligned.
Step 4: Mount the Supercharger
Carefully mount the Vortech supercharger onto the bracket. Make sure to use the correct bolts and tighten them to the manufacturer’s specifications.
Step 5: Connect the Intake Piping
Connect the supplied intake piping to the supercharger. Ensure all clamps are tight and that there are no leaks in the system.
Step 6: Install the Fuel System Upgrades
With the supercharger in place, upgrade the fuel system. This includes:
- Installing larger fuel injectors
- Replacing the fuel pump if necessary
Step 7: Reconnect the Battery and Check for Leaks
Reconnect the battery and start the engine. Check for any leaks in the intake and fuel system, making sure everything is functioning properly.
Step 8: Tune the Engine
After installation, it is crucial to tune the engine for optimal performance. This can be done using a handheld tuner or by visiting a professional tuner.
Expected Power Gains
Once the Vortech supercharger is installed and the engine is tuned, you can expect significant power gains. Depending on the specific setup and tuning, the Scion FR-S can see:
- Horsepower increases of 50-100 HP
- Torque increases of 30-70 lb-ft
