Effective Compression Ratio Calculator Version v1.1


This is a simple calculator for determining the effective compression ratio of a motor that might be under boost by a Turbo, Blower or other sorted odd devices. If your motor is normally aspirated boost is 0. The program takes PSI or BAR as the pressure but will only display the data in PSI. Hit the SAMPLE button to see how it works. The formula that is used is:

Effective Compression = ((Boost PSI / 14.7) + 1) * Current Static Compression Ratio

Pretty simple, but in any case here is a calculator for it.
