For starters, 9.0:1 CR, even with a thicker HG is potentially asking for major problems at higher boost levels. Water / methanol injection would certainly help stave off any potential detonation, but given the boost level which would be required to see 500whp, I doubt that it would cope.
Also, with such a large turbo, it would be extremely laggy on the road - unless I've missed the point and it's going to be a drag car Max boost at 4300rpm isn't something I could live with every day.
272 deg cams are pretty wild. Good luck with getting it to idle

İ Have 0.5 MM oversize pistons that will reduce CR a little. i am using 1.2 head hks gasget. didn't measured CR yet. you are right about detonation, the imporant think is tunning. with higher CR you can go same hp numbers with lower boost
we are planning to make fine adjustments with adj. cam gears and fix idle proplem.
if you want big power you should look for it at higher rpms.
