Stall Equation:
| From: | To: |
The High Stall Torque Converter Calculator estimates the stall speed of a torque converter based on engine horsepower and torque multiplication characteristics. It helps in selecting the appropriate torque converter for performance applications.
The calculator uses the stall equation:
Where:
Explanation: The equation calculates the RPM at which the torque converter will stall based on the input parameters, helping determine the optimal converter for specific performance needs.
Details: Accurate stall speed calculation is crucial for optimizing vehicle launch characteristics, improving acceleration, and ensuring proper torque converter selection for specific engine and transmission combinations.
Tips: Enter the K constant value, engine horsepower in hp, and torque multiplication factor. All values must be valid positive numbers.
Q1: What is stall speed in a torque converter?
A: Stall speed is the maximum RPM an engine can reach with the transmission in gear and the vehicle prevented from moving, indicating when the torque converter transfers power to the transmission.
Q2: How do I determine the K constant?
A: The K constant is typically provided by the torque converter manufacturer and varies based on converter design and characteristics.
Q3: What is a typical torque factor range?
A: Torque multiplication factors typically range from 1.8 to 2.5 for most performance torque converters, with higher values indicating greater torque multiplication.
Q4: How does stall speed affect performance?
A: Higher stall speeds allow the engine to operate in its optimal power band during launch, improving acceleration but may reduce fuel efficiency in normal driving conditions.
Q5: When should I use a high stall torque converter?
A: High stall converters are ideal for performance applications, racing, or vehicles with modified engines that produce power at higher RPM ranges.
