I have been having the same issues with my RT. I down graded from a V10 ram that at 90 seemed life 60 I thought because I was abot 2 feet above eveyone else. I got the RT with the 5.7 I figured my license would be safe. but when I leave for work I jump on the interstate and by the time I think I am at the speed of eveyone else I am runing about 95. I have ran it 0-130 with one of the hotties from work and she freaked out.

Yesterday I seen something about the SRT10 holy crap. Stuff the cast block V10 in one of these any that is just silly. To put the Viper V10 its got to be a death trip. The way these perform with a 5.7 or 6.0 is plenty enough. If the Viper V10 is also 8.0/488ci like my truck it would be purly silly no need for insurance don't register it and leave your license at home you won't come home with it if you don't. My truck with the 8.0 was alot more vehicle, much more weight but still at 110 it ran like a dream, even pulling I could run 85 without labor.

SRT10 pure silly (I want one)
