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.
