[QUOTE="Voltwings, post: 13804429, member: 155561"] Depending on your cam advance / retard, it changes, which is why its called the Dynamic ratio. I dont mean to insult your intellegance by saying that, but its not something so easily obtained. Typically though, i believe Dyanmic compression is always lower than static (11:1 on stock coyote). Heres another good article i found helpful. Particuarly this excerpt explaining the intake cams impact on DCR: "If you use your adjustable intake cam gear to close the intake valve earlier (advancing the cam gear), the amount of cylinder pressure bleeding up the intake port is reduced. The cylinder pressure builds up faster and you get a better burn."
