I don't know how that one website managed to do it, but everyone quotes them and thinks its right lol. Like I said though, a bigger combustion chamber, the same pistons/crank/rod, and a higher compression ratio? Wtf?

Didn't they bump up the compression a slight bit after 2000 or so?
After researching about other forced induction cars(DSM,Evo, etc) 8:5 or somewhere around there is a good number. No need to go higher and make the engine make power, that's what boost is for
I've seen some 9:x forced induction builds before and it seems a bit silly. They are often limited to the amount of boost they can run. Don't you gain something like 4% power for every full compression point? Might as well go low and be able to run more boost.

The 03/04 Cobra has a C/R @ 8.5 but thats a PD blower setup...
