Start by disconnecting any electrical connectors and vacuum lines attached to the intake manifold. Use a socket set to remove the bolts securing the manifold. Gently lift it off and set it aside.

2. Remove the Throttle Body

Next, detach the throttle body from the intake manifold. Disconnect the throttle position sensor and any other connections before removing the bolts that hold it in place.

Installing the Supercharger

With the necessary components removed, you can now proceed to install the supercharger. Follow these steps for a successful installation.

1. Position the Supercharger

Carefully place the supercharger onto the engine. Ensure that it aligns correctly with the mounting points. Use the provided hardware to secure it in place, but do not fully tighten the bolts yet.

2. Connect the Intake and Throttle Body

Reconnect the throttle body to the supercharger. Make sure all electrical connectors and vacuum lines are properly attached. Follow the supercharger kit instructions for specific connection details.

3. Install the Intercooler (if applicable)

If your supercharger kit includes an intercooler, install it according to the manufacturer’s guidelines. This may involve additional piping and connections.

Finalizing the Installation

After securing the supercharger and any additional components, it’s time to finalize the installation.

1. Tighten All Bolts

Using a torque wrench, tighten all bolts to the specifications provided in the supercharger kit manual. This ensures that everything is securely fastened and prevents any leaks.

Reconnect the negative terminal of the battery. Ensure that all connections are secure and that there are no loose wires.

3. Check Fluid Levels

Before starting the engine, check the engine oil and coolant levels. Top off if necessary to ensure proper operation.

Testing the Installation

Once everything is installed and checked, it’s time to test the supercharger.

1. Start the Engine

Start the engine and listen for any unusual sounds. Allow it to idle for a few minutes while checking for any leaks or issues.

2. Take a Test Drive

After ensuring everything is functioning correctly, take the car for a test drive. Pay attention to the throttle response and overall performance. You should notice a significant increase in power.
