When it comes to enhancing the performance of your Dodge Hellcat, one of the most effective modifications is a supercharger pulley swap. This guide will walk you through the process of safely increasing your Hellcat’s power to over 800 horsepower.
Understanding Supercharger Pulleys
A supercharger pulley swap involves replacing the factory pulley with a smaller one. This change increases the supercharger’s RPM, allowing it to generate more boost pressure, which translates to more horsepower. However, this modification must be done carefully to avoid engine damage.
Tools and Materials Needed
- Socket set
- Torque wrench
- Supercharger pulley removal tool
- New supercharger pulley
- New drive belt (if necessary)
- Engine oil (for lubrication)
- Safety goggles
- Work gloves
Preparation Steps
Before starting the swap, ensure your vehicle is parked on a level surface and the engine is cool. Gather all tools and materials to streamline the process.
Safety Precautions
Always wear safety goggles and gloves when working on your vehicle. Disconnect the battery to prevent any electrical issues during the installation.
Step-by-Step Installation Guide
Step 1: Remove the Engine Cover
Start by removing the engine cover. This usually requires a few bolts or clips. Keep them in a safe place for reinstallation.
Step 2: Disconnect the Supercharger Belt
Locate the tensioner pulley and use a wrench to relieve tension on the supercharger belt. Carefully slide the belt off the supercharger pulley and set it aside.
Step 3: Remove the Existing Pulley
Using the supercharger pulley removal tool, carefully remove the existing pulley. Follow the manufacturer’s instructions for the tool to avoid damaging the supercharger.
Step 4: Install the New Pulley
Lubricate the new pulley with a small amount of engine oil. Align it properly on the supercharger shaft and press it into place. Ensure it is seated correctly.
Step 5: Reattach the Supercharger Belt
Reinstall the supercharger belt over the new pulley. Make sure it is aligned properly with all pulleys to prevent slippage.
Step 6: Reinstall the Engine Cover
Once everything is secured, reinstall the engine cover and tighten all bolts or clips to the specified torque settings.
Post-Installation Checks
After completing the installation, it’s important to conduct some checks before hitting the road.
- Ensure all tools are removed from the engine bay.
- Double-check the belt alignment.
- Reconnect the battery.
- Start the engine and listen for any unusual noises.
Tuning Your Hellcat
After a pulley swap, it’s highly recommended to have your Hellcat tuned. This ensures that the engine management system is calibrated to handle the increased boost and power output safely.
Choosing a Tuner
Select a reputable tuner who specializes in Dodge vehicles. They will adjust fuel maps, ignition timing, and other parameters to optimize performance while maintaining safety.
Conclusion
A supercharger pulley swap is a straightforward modification that can yield significant power gains for your Hellcat. By following this guide and ensuring proper tuning, you can safely increase your vehicle’s performance to over 800 horsepower. Always remember to prioritize safety and consult professionals when necessary.
