Maf location, iats and heat issues.

To add to this.

Most Turbo cars making 600 on the stock motor reliably are running E85. Is that true?

Parasitic losses to spinning the S/C. I have read more than once that it takes up to 80 hp to spin a Vortec S/C. I know it will have a lot of variables, but it's a good number to think about, that puts a 450 whp S/C cars' engine feeling the same stress as a 530 whp turbo car. Am I wrong on that assumption?

Somewhat. turbo setups induce higher pumping losses and have to deal with egt's that a supercharged engine never will.
