Isnt it tother way around? supercharger disengages once the turbo has spooled up? hence smoke and loss of torque if the belt slips, but no loss of top end power. the belts do need to be pretty tight and in good condition, moisture and oil free, or you will get sod all boost until the turbo wakes up.
