Static compression ratio with boost
WebThe static CR needed to reach 9:1 DCR, for the 292 cam mentioned above, is around 12:1. This lowering of the compression ratio, due to the late closing of the intake valve, is the primary reason cam manufactures specify a higher static compression ratio for their larger cams: to get the running or dynamic CR into the proper range.
