Introduction
The Brake Mean Effective Pressure (BMEP) is a crucial metric in engine performance analysis. It helps you evaluate the efficiency and power output of an engine by considering two key variables: Torque (lb-ft) and Displacement (in^3). Calculating BMEP is essential for engineers, mechanics, and enthusiasts interested in optimizing engine performance. In this article, we’ll introduce you to our BMEP Calculator, provide the formula, a step-by-step guide on how to use it, offer an example, address frequently asked questions, and conclude with its importance.

Formula
The formula to calculate Brake Mean Effective Pressure (BMEP) is as follows:
BMEP = 150.8 * T / D
Where:
- BMEP is the Brake Mean Effective Pressure.
- T is the Torque in pound-feet (lb-ft).
- D is the Displacement in cubic inches (in^3).
Example
Let’s work through an example to demonstrate the calculation:
Suppose you have an engine with a Torque (T) of 250 lb-ft and a Displacement (D) of 300 in^3. To find the BMEP:
BMEP = 150.8 * 250 / 300
BMEP ≈ 125.67 psi (pound-force per square inch)
So, the Brake Mean Effective Pressure for this engine is approximately 125.67 psi.
