Tips on choosing appropriate dynamometers
Below is a MRR and PLR article in category Vehicles -> subcategory Other.
Tips for Choosing the Right Dynamometer
To achieve peak performance in a drag car or bike, especially when using modifications like boost or nitrous, a suitable inertial chassis dynamometer is essential. Look for models with large, clean drums that offer excellent grip. Avoid dual rollers for this purpose.
Key Considerations
1. Dynamometer Type:
- For high-performance setups, an inertial dyno is ideal. It captures the power curve accurately.
- A braked system is unsuitable for this application.
2. Equipment Necessities:
- Ensure the dynamometer has powerful fans and airflow.
- Having an experienced operator is crucial for accurate results.
3. When to Use a Braked System:
- If you're tuning a stock or mildly modified vehicle’s fuel injection or carburetor system, a decent braked system with twin rollers and a gas analyzer is more appropriate.
Buying Tips
Consider your primary needs when selecting a dynamometer:
- Inertial Dynos: Usually cheaper but harder to control as they don't allow for steady RPM holding.
- Braked Dynos: More suited for diagnosing and health-checking stock or mildly tuned vehicles.
Preparing for a Dynamometer Session
To ensure accurate results:
- Check and, if necessary, change the oil and filter.
- Ensure the air filter is clean.
- Verify coolant levels and check for leaks.
- Inspect tire pressure and condition, particularly for powerful vehicles.
- Ensure the fuel tank is adequately filled and other additives like nitrous or water injection are topped up.
- Confirm that spark plugs are correctly gapped and in good condition.
Remember, dynamometer testing is no harder on your vehicle than a fast drive on the motorway and can often be safer for your engine. By controlling the test conditions, you can obtain reliable and useful data for tuning and performance optimization.
