Reasons for removing A/C?

If it wasn't turbo'd, or if the person had an A/c friendly turbo set-up, the previous person also may have removed it to free up any parasitic drag on the crank pulley (since the a/c belt obviously is spun by it).

Really there isn't any horsepower drag, just inertia, with the system off. To prevent that, you could just take the belt off before you go racing. The whole system weighs maybe 40-50 pounds. Seems to me to be worth keeping.
