If you mean stress as in wear and tear, no. There is however a parasitic power loss due to the engine using some of its power to overcome the resistance of spinning the blower pulley. Example; the blower may provide a total extra 80hp, but 10hp of the total could go to power itself, so you'd only see a 70hp gain.

A turbo is more efficient as it is powered by waste gas and requires no effort on the engine mechanics itself to spin it.
