Torque Converter Stall Equation:
| From: | To: |
The Torque Converter Stall Equation calculates the stall speed of a torque converter based on a constant factor and the engine's horsepower. Stall speed is the maximum RPM the engine can reach with the transmission in gear and the vehicle stationary.
The calculator uses the Torque Converter Stall equation:
Where:
Explanation: The equation provides an estimate of the torque converter's stall speed based on the engine's power output and a constant factor that accounts for torque converter design characteristics.
Details: Proper stall speed calculation is crucial for optimal vehicle performance, especially in racing applications. It affects launch characteristics, acceleration, and overall drivability.
Tips: Enter the constant factor (K) and engine horsepower (HP). Both values must be positive numbers for accurate calculation.
Q1: What is a typical range for the constant factor K?
A: The constant K typically ranges from 2000 to 3500, depending on the torque converter design and application.
Q2: How does stall speed affect vehicle performance?
A: Higher stall speeds allow the engine to reach its power band faster, improving acceleration but may reduce fuel efficiency in daily driving.
Q3: When should I use this calculation?
A: This calculation is useful when selecting or designing a torque converter for performance applications, racing, or custom vehicle builds.
Q4: Are there limitations to this equation?
A: This provides an estimate and actual stall speed may vary based on torque converter design, engine characteristics, and other factors.
Q5: Can this be used for all types of torque converters?
A: While the basic principle applies, specific torque converter designs may require more complex calculations for precise results.
