Crank to Wheel Horsepower Calculator

Formula

The formula to calculate the Crank to Wheel Horsepower (CWHp) is:

\[ CWHp = BHp \times (1 - L) \]

Where:

\( CWHp \) is the Crank to Wheel Horsepower (hp)
\( BHp \) is the Brake Horsepower, the total horsepower before power loss (hp)
\( L \) is the percentage of power loss due to factors such as friction, heat, and other mechanical inefficiencies (decimal)

Definition

Crank to Wheel Horsepower (CWHp): The horsepower effectively transferred from the engine to the wheels of the vehicle, taking into account power loss.
Brake Horsepower (BHp): The total horsepower before power loss.
Power Loss Percentage (L): The percentage of power loss due to factors such as friction, heat, and other mechanical inefficiencies.
Significance: Understanding the Crank to Wheel Horsepower is crucial for evaluating the performance of a vehicle, as it represents the actual power available for driving the wheels.

Example

Let's say the Brake Horsepower (BHp) is 300 hp and the power loss percentage (L) is 0.15. Using the formula:

\[ CWHp = 300 \times (1 - 0.15) = 300 \times 0.85 = 255 \]

So, the Crank to Wheel Horsepower is 255 hp.
