Typhoon My personal opinion, as I looked at options, is that there was such a price difference between used R/T’s vs used SRT’s (and new I was not going to entertain until the Hellcat came out), that it just made sense to enhance the performance of my R/T, which I bought new in 2015, so I did. Stock, there is only 100hp difference and probably some other little performance things but there are SO MANY options out there for those R/T’s, including a very wide variety of superchargers. Again, my personal opinion. 👍🙂
