Whats interesting is OEM seem to be running pretty high CR . I notice the eco-boost ford V6 is 10.0:1 . Also the new Audi S4 and BMW 335i also run 10.0:1 CP (one SC and other twin turbo ).

Not sure on how much boost there running, my guess under 10lb boost.
Found nice test results between the two .

Comparison Test: 2010 Audi S4 vs. 2009 BMW 335i
