Cammed Infiniti G37 Sedan Dyno Day! This thing RIPS!!!

Introduction

This tutorial will guide you through the exciting process of dyno testing a cammed Infiniti G37 sedan, showcasing how to optimize performance for impressive results. Whether you're a car enthusiast or a DIY mechanic, this guide will help you understand the key steps involved in achieving a powerful build.

Step 1: Preparing the Vehicle for Dyno Testing

Before hitting the dyno, ensure your vehicle is ready for optimal performance.

• Check Engine Health

  • Inspect fluid levels (oil, coolant, etc.).
  • Ensure there are no leaks or warning lights on the dashboard.

• Warm Up the Engine

  • Start the engine and let it run for about 10-15 minutes to reach operating temperature.

• Install Necessary Equipment

  • If applicable, connect a wideband O2 sensor to monitor air-fuel ratios.
  • Ensure that all necessary tools and equipment are available for adjustments.

Step 2: Setting Up the Dyno

Proper setup on the dyno is crucial for accurate measurements.

• Choose the Right Dyno Type

  • Decide between a chassis dyno (measures power at the wheels) and an engine dyno (measures power at the engine crankshaft).

• Secure the Vehicle

  • Strap the car securely to the dyno to prevent movement during testing.

• Configure Dyno Settings

  • Input the vehicle's specifications such as weight and tire size into the dyno software.

Step 3: Running the Dyno Test

With everything set up, it's time to run the dyno test.

• Perform Test Runs

  • Start with a few baseline runs to gather initial performance data.
  • Make sure to gradually increase RPMs to avoid stressing the engine.

• Monitor Performance Metrics

  • Keep an eye on horsepower, torque, and air-fuel ratio readings during the runs.

• Record Data

  • Save all data for analysis, focusing on areas like peak horsepower and torque curves.

Step 4: Analyzing Results and Making Adjustments

Post-dyno analysis is crucial for optimizing performance.

• Review Data Logs

  • Look for trends in power delivery and identify any areas needing improvement.

• Adjust Tune

  • If necessary, adjust the engine tune based on the data collected, focusing on air-fuel ratios and ignition timing.

• Re-test if Needed

  • After adjustments, run the dyno again to see if the changes yield better results.

Conclusion

By following these steps, you can effectively dyno test and tune a cammed Infiniti G37 sedan, pushing it toward becoming one of the fastest in the world. Remember to keep an eye on engine health and performance metrics, making adjustments as needed. As you progress, document your journey and share your results with fellow enthusiasts. Happy tuning!
