Frequently asked questions
- How do I calculate torque from horsepower?
- Use Torque (lb·ft) = HP × 5,252 ÷ RPM. For example, 400 HP at 6,000 RPM produces 400 × 5,252 ÷ 6,000 = 350.1 lb·ft of torque.
- What does higher torque at lower RPM mean?
- High torque at low RPM (common in diesels and turbocharged engines) means the engine feels strong when pulling away from a stop or climbing hills.
