1. What is Torque Converter Size?

The torque converter size is determined primarily by the engine's torque output. Proper sizing ensures optimal performance, efficiency, and longevity of your transmission system.

2. How Does the Calculator Work?

The calculator uses torque and application type to determine the recommended size:

Where:

• Torque — Engine torque output in pound-feet (lb-ft)
• Application — Street, Racing, or Towing application

Explanation: The calculation accounts for the relationship between torque output and the physical size needed for proper operation, with adjustments for different use cases.

3. Importance of Proper Sizing

Details: Correct torque converter sizing is crucial for optimal power transfer, fuel efficiency, and preventing premature wear on transmission components.

4. Using the Calculator

Tips: Enter your engine's torque output in lb-ft and select the primary application type. The calculator will recommend an appropriate torque converter size.

5. Frequently Asked Questions (FAQ)

Q1: What happens if I use the wrong size torque converter?
A: Improper sizing can lead to poor performance, overheating, reduced fuel efficiency, and potential transmission damage.

Q2: How do I measure my engine's torque?
A: Torque values are typically provided in your vehicle's specifications or can be measured with a dynamometer.

Q3: Does stall speed affect torque converter size?
A: Yes, stall speed requirements are considered in the sizing calculation, though this calculator focuses on the diameter aspect.

Q4: Should I round up or down if between sizes?
A: For street use, round down for better efficiency. For racing, round up for better performance.

Q5: Are there other factors to consider beyond size?
A: Yes, stall speed, fin angle, and internal components are also important considerations when selecting a torque converter.
