In response to your question, 10.5:1 is probably starting to push your luck a bit. One of the factors that influences how high you can go in the static comp is the combustion chamber design. As a general rule of thumb, the younger design the engine, the more comp you'll get away with.

A couple other things to consider-
Keep the incoming boost nice and cold-ie a BIG i/c.
Smooth the combustion chambers to eliminate any hot spots.

You may get away with it-but it will require premium or better, and some good plugs.

Alternately, attack the chambers with a grinder and pull 0.5-1.0 compression points out of it that way.
