Ambiguity in the compression ratio spec for the Kent engine
#30693 from Bill Manofsky · Not recommended · Minutes (2021-07 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change because the GCR's standard for calculating an
engine's compression ratio already includes the volume above the top ring and below the top of the piston. Please see the
definition of compression ratio in Appendix F (Technical Glossary) and Appendix G (Facts, Formulas, and Measurement
Standards).
