My 605 runs 170 to 210 on the street with the MP fiscous fan, no shroud, aluminum radiator, and stock pulleys. One thing to remember driving it on the street, you start 'playing' it will try and kill you from time to time. One tire will bite and it will send you into the next lane in the blink of an eye. Don't get me wrong that much hp on the street is about as much fun as you can have and keep your cloths on. Dave
