Your engine's static compression ratio is easily calculated if you know six measurements or volumes: Bore-- The diameter of the cylinder bore Stroke-- The distance the piston travels in the cylinder

RB Racing's Advanced Dynamic Compression Ratio Calculator calculates your engine's compression ratio for changes in camshafts, rod length, static compression, boost and altitude.

RB Racing's Boost Compression Ratio Calculator corrects your engine's static compression for boost and altitude factors

This calculator will calculate both Static and Dynamic compression ratio. Compression Ratio is the ratio of an engine's cylinder volume vs. its combustion chamber size.

The Engine Compression Ratio calculator computes the compression ratio based on the cylinder bore (diameter), stroke length and the clearance volume. Engine Compression Ratio (CR): The ratio is returned as a real number. The compression ratio isn't just a number: it's one of the greatest determining factors in engine building.

Get your engine's optimal compression ratio and total displacement in no time flat! Just complete your engine setup, click calculate, and you’re on your way to maximum performance. Use (-) for Dome and (+) for Dish.

Check to see what your static and dynamic compression is based on engine parameters. The compression ratio is simply the ratio of the uncompressed volume in the cylinder to the compressed volume. The compressed volume for the dynamic compression ratio is the same as the static compression ratio.

Try the compression ratio calculator today. Easily calculate the static compression ratio of your engine. Takes into account deck height, dome or dish size, flat top pistons, and more.

This simple tool allows you to calculate the STATIC compression ratio of an engine. It will also allow you to calculate the engine displacement in Liters and Cubic Inches. See Below for explanations of the fields required.

Use our compression ratio calculator to accurately determine your engine's static compression ratio by measuring key components like bore, stroke, and combustion chamber volume.
