I hate to branch of topic but i must know. I live in the tri-state arena of GA/Tn/AL and i seen someone from AL driving a Charger "daytona" edition and it said "RT" on the front grill. I asked him if he was pleased with the performance, he ignored me and drove off. Anyways whats the difference betweet rt/srt/srt-8? i know ive seen the srt-10 vipers (seen one friday night). Whats horsepower and Liter difference?
