User Reviews

The CR Calculator app is well-regarded among Honda engine enthusiasts for its helpfulness and accuracy when the right data is input, making engine building easier. However, users commonly report issues such as the inability to enter negative piston volume values, missing data for certain engine series, UI problems on some devices, and incorrect specific engine data. While recommended by many, the app remains focused on Honda engines and is not a universal calculator.

Pros

App is helpful and makes life easier for engine builders, especially Honda Civic enthusiasts.
Generally accurate calculations when specific data is provided.
Long-standing positive user base who recommend the app.
Good job creating the app with useful features.

Cons

Cannot input negative values for piston cc or dished pistons, which limits accuracy.
Missing key information for various Honda engine series, e.g., J series and C series motors.
User interface issues on some devices like Galaxy S7 Edge where drop-down lists do not show.
Some specific data, e.g., K24 engine piston volumes, is incorrect.
App is not a universal compression ratio calculator; limited to Honda engines.
