I'm not compeltely sure if it's compatible with underdrive pulleys or not. I would think that it would be. The new unit is suppose to increase what 10hp? Pretty trick piece if you ask me. I have a electric water pump on mine and love it. Keeps the water relatively cool too. Runs around 190* all the time.
