1. What is the Stall Converter Formula?

The Stall Converter formula calculates stall speed in revolutions per minute (rpm) based on a constant factor and horsepower. It is commonly used in automotive applications in Australia to determine the appropriate stall converter for vehicle performance.

2. How Does the Calculator Work?

The calculator uses the Stall Converter formula:

Where:

• \( Stall \) — Stall speed in rpm
• \( K \) — Constant factor (varies by application)
• \( HP \) — Horsepower (hp)

Explanation: The formula calculates the stall speed by multiplying a constant factor by the square root of the horsepower.

3. Importance of Stall Calculation

Details: Accurate stall speed calculation is crucial for selecting the right torque converter for optimal vehicle performance, especially in racing and high-performance applications.

4. Using the Calculator

Tips: Enter the constant factor (K) and horsepower (HP) values. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical K value range?
A: K values typically range from 2000 to 3000, but may vary depending on specific vehicle and application requirements.

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.

Q3: When should I use this calculation?
A: Use this calculation when selecting or upgrading a torque converter for performance applications, particularly in Australian automotive contexts.

Q4: Are there limitations to this formula?
A: This formula provides an estimate and actual performance may vary based on transmission type, vehicle weight, and other factors.

Q5: Should I consult a professional for stall converter selection?
A: For optimal performance and to avoid transmission damage, it's recommended to consult with automotive professionals when selecting stall converters.
