Overview
Compression ratio measures how much air-fuel mixture is compressed in an engine cylinder. Higher ratios generally mean more power and efficiency but require higher octane fuel. Critical for engine building and tuning.
💡
Pro Tips
Bigger bore or longer stroke increases the compression ratio.
Thicker head gaskets are an easy way to lower compression for turbo builds.
Fun Fact
Did you know? Static compression is only half the story; 'Dynamic' compression takes valve timing into account.
