I had an '05 hemi magnum back in '05. It was really nice to drive. I dynoed it and got 278 hp at the wheels. This was with 400 miles on the car and on 87 octane. Yours will do more, the newer ones make more power. I sold it when I went to start it one day and the battery was almost dead. It was almost dead because I had quit driving it due to infatuation with my dually, which I had gotten not long after getting the magnum. I realized that making the payment on the magnum didn't make any sense if I wasn't going to drive it, so I sold it with 3300 miles on it.
