Does anyone know what the dynamic compression on our motors 89-93 is ?

gldiii SCCoA Lifetime Member Jun 30, 2004 #5 I believe those are correct "static" compression ratios. This calculator will give you dynamic ratios for different parameters: http://www.kb-silvolite.com/calc.php?action=comp

David Neibert SCCoA Admin Jun 30, 2004 #6 I think he is asking for the Effective compression ratio (static CR plus boost). With static compression of 8.2:1 and 12 pounds of boost, the Effective CR will be 14.89. Here is a link with several calculators. http://www.superford.org/garage/calculators/index.php#total_effective_engine_compression David
