Horsepower (hp) = (Torque × RPM) / 5,252
Where:
- Torque is measured in pound-feet (lb-ft)
- RPM (revolutions per minute)
Since you haven't provided the torque and RPM values for the 439 CC motor, I can't calculate the exact horsepower. However, here's a general estimation:
Assuming a conservative torque value of 30 lb-ft and a typical maximum RPM of 9,000 for a small engine like this, we can calculate the horsepower:
Horsepower (hp) = (30 lb-ft × 9,000 RPM) / 5,252
= (270,000 lb-ft-RPM) / 5,252
≈ 51.42 horsepower
This is a rough estimation based on typical values for a 439 CC motor. The actual horsepower may vary depending on the specific engine design, modifications, and operating conditions.
