How much horsepower gain you can get from a certain amount of boost? Enter boos psi into the calculator to determine the horsepower increase from a given boost level.
How to Use the Calculator
This calculator has two modes: Basic and Advanced. Let’s walk through how to use each mode with some example values.
1. Basic Calculator
- Enter Boost (PSI): Input the boost pressure in PSI. For example, enter
20PSI. - Horsepower Gain: If you already know the boost, leave this blank to calculate the horsepower gain. Otherwise, enter the horsepower gain to find the required boost.
2. Advanced Calculator
- Enter Boost (PSI): Input the boost pressure in PSI. For example, enter
15PSI. - Efficiency Factor (%): Enter the efficiency of the engine. For instance, enter
80%. - Base Horsepower (HP): Enter the base horsepower of the engine. For example, enter
300HP. - Total Horsepower Gain: This field will show the total horsepower gain after you click calculate.
Formula
For the basic calculator, the formula to calculate horsepower gain is:
Variables
| Variable | Description |
|---|---|
| HP | Horsepower Gain (HP) |
| B | Boost (PSI) |
How To Calculate Boost HP
Example 1: Basic Calculator
- Boost (PSI): 25 PSI
- Horsepower Gain: Leave blank
To calculate the Horsepower Gain:
Use the formula:
So, the horsepower gain is 1.75 HP.
Example 2: Advanced Calculator
- Boost (PSI): 10 PSI
- Efficiency Factor (%): 85%
- Base Horsepower (HP): 250 HP
To calculate the Total Horsepower Gain:
1. Convert the efficiency factor to a decimal:
2. Calculate the total horsepower:
2. Calculate the horsepower gain:
So, the total horsepower gain is 21.25 HP.
