I dident even realize how hard my smog pump was to turn. must have siezed after all the miles!! my bro has another spare one in the garage, and that is EASY to turn by had, no, not mine. wow, that must have seriously been eating up like 25 hp. i can barely turn it by hand. just telling you guys if you havent yet, go out, slip off off ur belt and see how hard it is for you to turn the smog pump by hand, should go really easy, not much resistance

The smog pump doesn't use more then 2-3hp max, removing it saves like 10lbs (weighed it on my bathroom scale) and removes clutter from the engine bay. Keep it connected if you run cats.
