I have found once you reach a certain horsepower it is more for bragging rights that anything. There is no possible way to put that kind of power down. If i used all my power i would go slower then if conservitive. I still need to find the right amount of boost to run so i dont go up in smoke at highway speeds. Please tell your friend if he ever decides to drive it again before he sells it to shoot me a pm. There is nothing i would enjoy more then running a fellow honda owner.
