Not as bad as you would think. Both the Maggi and the Edelbrock superchargers have bypasses that keep the peristaltic drag down to about a third of a horsepower and 0 boost until engine demand closes the bypass. (Not like the old style roots blowers, which were "on" all the time.)
I can still get 21-22 mpg on the highway at 70 mph.
