MAF to HP Calculator

Formula

The formula to calculate the Horsepower (HP) from Mass Air Flow (MAF) is:

\[ HP = \frac{MAF \cdot ρ \cdot VE \cdot D \cdot RPM}{3456} \]

Where:

\(HP\) is the horsepower
\(MAF\) is the mass air flow
\(ρ\) is the air density (kg/m³)
\(VE\) is the volumetric efficiency
\(D\) is the engine displacement (liters)
\(RPM\) is the revolutions per minute

What is a MAF to HP Calculator?

A MAF to HP calculator is a tool used to estimate the horsepower of an engine based on the mass air flow (MAF), air density, volumetric efficiency (VE), engine displacement, and RPM. This calculator is particularly useful for automotive enthusiasts and professionals who want to understand the performance characteristics of an engine. By inputting the relevant parameters, the calculator can provide an estimate of the engine’s horsepower, which is a key indicator of its performance capabilities.

Example Calculation

Let's assume the following values:

Mass Air Flow (MAF) = 100 g/s
Air Density (ρ) = 1.225 kg/m³
Volumetric Efficiency (VE) = 0.85
Engine Displacement (D) = 2.0 liters
Revolutions Per Minute (RPM) = 6000

Using the formula to calculate the Horsepower (HP):

\[ HP = \frac{MAF \cdot ρ \cdot VE \cdot D \cdot RPM}{3456} = \frac{100 \cdot 1.225 \cdot 0.85 \cdot 2.0 \cdot 6000}{3456} ≈ 54.88 \text{ HP} \]

The Horsepower (HP) is approximately 54.88 HP.
