Multiply the Wheel Horsepower (WHP) by , where DL is the drivetrain loss as a decimal.
The WHP to HP Calculator helps estimate the engine’s horsepower (HP) from the measured Wheel Horsepower (WHP) by accounting for drivetrain losses. Drivetrain losses represent the power reduction caused by transmission, axles, and other components.
Formula
HP = WHP ∗
| Variable | Definition |
|---|---|
| HP | Horsepower at the crankshaft (engine power) |
| WHP | Wheel Horsepower (measured at wheels) |
| DL | Drivetrain Loss (as a decimal) |
Solved Calculations
Example 1
A car with a WHP of 400 and a drivetrain loss of 15% (0.15).
| Variable | Value |
|---|---|
| WHP | 400 HP |
| Drivetrain Loss (DL) | 0.15 |
| HP | 470.6 HP |
Example 2
A motorcycle with a WHP of 150 and a drivetrain loss of 10% (0.10).
| Variable | Value |
|---|---|
| WHP | 150 HP |
| Drivetrain Loss (DL) | 0.10 |
| HP | 166.7 HP |
What is WHP to HP Calculator?
The WHP (Wheel Horsepower) to HP (Horsepower) Calculator is a useful tool which is designed to convert wheel horsepower (measured at the wheels) into crank horsepower (measured at the engine’s crankshaft).
This tool accounts for power losses that occur through drivetrain components, providing accurate performance metrics for vehicles.
For example, a 400 WHP to HP conversion reveals the crank horsepower after factoring in drivetrain loss percentages. Similarly, the calculator can determine values for motorcycles, 500 WHP to HP, or even specialized cases like 203 WHP to HP.
It is invaluable for automotive enthusiasts assessing engine performance or professionals tuning vehicles for optimal output.
By using straightforward inputs like drivetrain loss percentages, this calculator simplifies the complex task of converting WHP to crank HP or WHP to BHP, enhancing the accuracy of performance evaluations.
Final Words:
To conclude, the WHP to HP Calculator streamlines horsepower conversion, offering a precise way to assess vehicle performance. It’s an essential tool for car and motorcycle enthusiasts, ensuring informed decisions in tuning and performance analysis
