I don't know, but as power output is directly proportional to compression ratio, I'd guess the power would rise in proportion to the compression. You would of course have to bear in mind the fact that the true compression is nothing like the calculated one because the volumetric efficiency isn't that good. All this is a posh way of saying the power will increase, but nothing like the 15% talked of here.
