Just look at the calculator inputs for DCR...bore, stroke, rod length,static compression ratio, intake closing…no other factors. It is effective compression ratio whether you believe that is a useful piece of data or not.
That’s why I said define dynamic. The DCR I’m referring to is different than the what Wallace says.
To that end, since at least 1973 when my dad explained what effective compression ratio is I have never seen anyone that I think knows what they are taking about call that dynamic compression ratio.
That’s the wrong term. It’s effect compression ratio. Nothing dynamic about it and for some guys when you say dynamic will go to a different place.
Dynamic compression ratio means absolutely nothing.
