Insight
Torque and Horsepower always cross at exactly 5,252 RPM. If a dyno sheet shows them crossing elsewhere, the data is incorrect!
Overview
Horsepower measures engine power output. Calculated from torque and RPM, or converted from kilowatts. Essential for comparing vehicles, motors, and mechanical systems.

Pro Tips
Torque is the 'grunt' that gets you moving, while horsepower is what keeps you going fast.
Track estimates (ET method) usually reflect 'Wheel Horsepower' which is 15-20% lower than engine HP.
