learn.whatIsHeading
Calculates or estimates engine horsepower from engine specifications or dyno testing. Indicates performance potential and capability.
공식
Method 1: Calculate from torque = (torque × RPM) ÷ 5252
- RPM
- RPM value — Variable used in the calculation
단계별 가이드
- 1Method 1: Calculate from torque = (torque × RPM) ÷ 5252
- 2Method 2: From displacement and compression ratio estimate
- 3Method 3: Dyno test measures actual output
- 4Factor in losses: 10-15% drivetrain, 5% accessories
풀어진 예시
입력

자주 묻는 질문
What's the difference between crank and wheel horsepower?
Crank HP: at engine; wheel HP: after drivetrain losses (10-15% lower for AWD, less for RWD).
How does boost (turbo/supercharger) increase horsepower?
Forced induction adds more air, enabling more fuel, increasing combustion power 30-50%.
