1. What is the Torque Converter Stall Speed Equation?

The torque converter stall speed equation calculates the RPM at which a torque converter will stall based on engine torque, inertia, and a dimensionless constant K. This is important for automotive performance tuning and transmission design.

2. How Does the Calculator Work?

The calculator uses the stall speed equation:

Where:

• \( K \) — Dimensionless constant specific to the torque converter
• \( T\_engine \) — Engine torque in Newton-meters (Nm)
• \( \text{inertia} \) — Rotational inertia in kilogram meters squared (kg m²)

Explanation: The equation calculates the RPM at which the torque converter will stall based on the relationship between engine torque and system inertia.

3. Importance of Stall Speed Calculation

Details: Accurate stall speed calculation is crucial for proper torque converter selection, vehicle performance optimization, and preventing transmission damage.

4. Using the Calculator

Tips: Enter the dimensionless constant K, engine torque in Nm, and inertia in kg m². All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is torque converter stall speed?
A: Stall speed is the maximum RPM an engine can reach when the transmission is in gear and the vehicle is prevented from moving.

Q2: How is the K constant determined?
A: The K constant is specific to each torque converter design and is typically provided by the manufacturer or determined through testing.

Q3: What affects stall speed?
A: Stall speed is affected by engine torque, torque converter design, and the rotational inertia of the system.

Q4: Why is stall speed important for performance?
A: Proper stall speed matching ensures the engine operates in its optimal power band during acceleration.

Q5: Can this calculator be used for all torque converters?
A: This calculator provides a general estimation. Actual performance may vary based on specific torque converter characteristics and vehicle setup.
