Yes, several of them do, and going by the definition given on the sites above, they shouldn't. From what I'm lead to believe Dynamic Compression is just like Static Compression- swept volume over combustion chamber volume. The volume of the cylinder at BDC over the volume at TDC, or in the case of Dynamic Compression, the volume of the cylinder at IVC over the volume of the cylinder at TDC. Density of the intake charge has no effect on these values.

I'm mostly interested in knowing what kind of dynamic compression ratios people have luck with on boosted cars so I can try to piece together camshaft data to figure out good combinations of cams and static compression ratios.
