Compression Ratio Calculator

Static and Effective Compression Ratio

Bore (in)

Stroke (in)

Gasket Thickness (in)

Deck Height (in)

Piston Top Volume (cc)

Combustion Chamber Volume (cc)

Boost (psi)

Enter bore, stroke, gasket thickness, deck height, piston top volume, and combustion chamber volume to calculate static compression ratio. Add boost to calculate effective compression ratio too.
