Torque Converter

What is a Torque Converter?

A Torque Converter is a type of fluid coupling used in automatic transmissions to transfer rotational power from the engine to the transmission without a manual clutch. It allows the vehicle to stay in gear while idling and provides smooth acceleration.

A Torque Converter Calculator helps determine torque multiplication, stall speed, and efficiency based on factors like engine RPM, fluid dynamics, and converter size.

Why Use a Torque Converter?

A torque converter is essential for:

• Automatic Transmission Vehicles – Replaces the clutch in manual transmissions.
• Smooth Power Transfer – Allows gradual acceleration without stalling.
• Torque Multiplication – Provides extra power at low speeds for better performance.
• Fuel Efficiency & Comfort – Reduces jerks and improves driving experience.
• Heavy-Duty Applications – Used in trucks, industrial machines, and racing vehicles.

A Torque Converter Calculator is useful for:

• Selecting the Right Converter for a Vehicle
• Determining Optimal Stall Speed (RPM at which power transfers)
• Analyzing Performance in Racing & Heavy-Duty Applications

How to Use a Torque Converter Calculator?

1. Input Engine Specs – Enter engine RPM, horsepower, and torque.
2. Choose Converter Type – Select stall speed and size.
3. Calculate Torque Multiplication – The tool estimates efficiency and output power.
4. Analyze Results – Compare different converters for performance or fuel efficiency.

Example Calculation:

• Engine RPM: 3000 RPM
• Stall Speed: 2500 RPM
• Torque Multiplication: 2.5x
• Output Torque: (Engine Torque) × (Multiplication Factor)

When to Use a Torque Converter or Its Calculator?

Use a torque converter when:

• Driving an Automatic Vehicle – Standard in most automatic transmissions.
• Towing Heavy Loads – Provides extra power for towing or off-roading.
• Upgrading for Performance & Racing – Helps optimize acceleration.
• Customizing Transmission Systems – Needed in high-performance and modified vehicles.

Use a Torque Converter Calculator when:

• Choosing a Converter for a Vehicle – Matches stall speed to engine power.
• Upgrading a Transmission System – Optimizes power transfer.
• Comparing Performance vs. Fuel Efficiency – Helps in tuning for racing or daily driving.
