EVAN; Your comments on effect of altitude on a supercharged engines performance are correct, except that you forgot to mention the offsetting effect that helps to keep these cars faster at tracks such as Las Vegas. Since a blower takes HP to compress the ambient air, less dense air will lower the blower output pressure, but will also lower the Hp needed to compress it. The power needed to run a blower is significant, so the 'gain' from reduction in load is also significant.
