12:1 that can be controlled VIA VCT. 5.0l mustang guys have super high compression aswell, they boost em and using tuning can effectively reduce the static compression ratio. same on the fiesta, really cool stuff. also direct injection lets you run higher CR as it cools the combustion chamber down drastically by comparison to MPFI. look at the VW 2.0T FSI, direct injection a boosted running 10.3:1 compression factory. almost unheard of as a factory boosted motor
