Boost Compression Ratio, blower or turboBoost Compression Calculator

(1) Program (.exe)
Calculates the effective compression ratio when you factor in the boost from a blower or turbo. We all have a general idea of the proper gas to run for a normally aspirated engine with a given compression ratio, but what about when you add boost? This little program will give you the equivalent normally aspirated compression ratio. You shouldn't even consider building one of these engines without knowing this number.
  • Input: Static Compression Ratio
  • Input: Boost PSI
  • Output: Effective Compression ratio

Runs on all versions of Microsoft Windows

Part of the "Engine Pack" collection of programs.
