## Formulas

The following formula is used to convert boost from supercharger into generated horsepower.

**Boost to HP Formula**

HP = B * .07

**HP to Boost Formula**

B = HP / .07

- Where HP is the horsepower
- B is the boost (PSI)

## Boost Definition

Boost is defined as the total pressure, most often measured in PSI, that a turbocharger or supercharger injects into the engine of a car. The injected air increases the horsepower of the engine for a small period of time.

## Boost to Horsepower Example

How to calculate horsepower from boost?

**First, determine the total amount of boost.**Measure the pressure in PSI delivered by the supercharger.

**Next, determine the generated horsepower.**Calculate the estimated gained horsepower from the boost using the equation above.

## FAQ

**What is boost?**

Boost is the pressure delivered to an engine from a supercharger that temporarily increases the engine horsepower/output.
