11.5 compression and boost-why not! 2010 C6 Z06 off the dyno. Car has A&A V3 Si trim, some shiny new Pfadt headers and a Alky Control Meth kit.
The gains are impressive to say the least-especially for 7.5lbs of boost.

Well....on pump gas I would say your nuts. lol. That is pretty brave in my book. However, I was contemplating next year to throw a 5.3 together but use the 4.8 flat top pistons. That would give 11.5 compression if my numbers are correct. I would run pump gas E85 AND METH/WATER INJECTION also.
Pretty sick numbers though! It has to be on the ragged edge though on pump gas. That is some serious coin if she blows.

My $0.02... OP -
I've heard the "You're Nuts!" comment several times here as well.
I ran with the stock CR (10.4) and 11 lbs of boost on my LT1 for 40,000 miles with zero issues - of course I did also use a LOT of meth to keep everything bolted together. However, when I turned up the manual boost controller to 13 lbs, that's when things started to go pear-shaped!
Have fun - good luck - Merry CHRISTmas!!!
