In the world of automotive engineering, piston compression height is a crucial factor when designing and building performance engines. It directly impacts the overall performance and efficiency of the engine.

In this post, we introduce our easy-to-use Compression Height Calculator, which allows you to quickly compute the compression height of a piston. We will also go through the formula behind the calculator and provide a step-by-step example using different numbers.

Understanding Compression Height

Compression height refers to the distance between the center of the wrist pin and the crown of a piston. This measurement plays a vital role in achieving the desired quench in performance engines.

Quench is the distance between the piston’s flat top and the cylinder head’s flat surface when the piston is at the top dead center (TDC). The correct quench height helps prevent detonation, improves combustion efficiency, and contributes to overall engine performance.

Compression Height Formula

What is the formula for compression height? The formula used to calculate the compression height (CH) is as follows:

CH = BH – 0.5 * CS – RL – DC

Where:

  • CH represents the compression height
  • BH is the block height
  • CS is the crank stroke
  • RL is the rod length
  • DC is the deck clearance

Example: Calculating Compression Height

For this example, we will use the following dimensions:

  • Block height (BH): 8 inches
  • Crank stroke (CS): 3.5 inches
  • Rod length (RL): 2 inches
  • Deck clearance (DC): 1.5 inches

Using the formula above, we can calculate the compression height:

CH = BH – 0.5 * CS – RL – DC

CH = 8 – 0.5 * 3.5 – 2 – 1.5 CH = 8 – 1.75 – 2 – 1.5

CH = 2.75 inches

In this example, the compression height is 2.75 inches.
