why not? the only thing that's limited is the amount of boost you can run, NOT the amount of power you can make vs the inverse. if low compression/high boost was the "only" way to do it, then we would be running some stupid crap like 50PSI into a 4 to 1 compression engine.
really, high boost/low compression isn't any better or worse than low boost/high compression. they are both just a means to an end. the engine compresses air and the supercharger compresses air. all your doing is switching up which one does the most work.
So you are saying that "conventional wisdom" is wrong? And, why does every purpose-built forced induced factory made car start with about 8:1 to 9:1?? The (the new ZR1 is 9.1:1 and the Bugatti Vetron is 9:1 and the Shelby GT500 Super Snake is 8.4:1).
Sure, you can 'tune around' higher compression, but starting with a clean sheet of paper and conventional wisdom dictates a lower static compression ratio.
I love the new 5.0, I just think Shelby went for the easy bolt on instead of changing the pistions...
