WebDynamic compression. Calculating static compression is simply the ratio of the total volume in the cylinder at bottom dead center (BDC) to the compressed volume at top dead center (TDC). The dynamic compression ratio is similar as it is the ratio of volumes. The compressed volume is the same in both static and dynamic compression. WebFeb 24, 2024 · Reading a Cam Card: Rocker Arm Ratio (Rocker Ratio) On that same line in this cam card, the lift at the valve has increased from 0.321-inch at the lobe, to 0.545-inch at the valve. This is accomplished through the rocker ratio. Note that the card calls this ratio out at 1.7:1. If we multiply 0.321 x 1.7 = 0.545-inch. chireal
