I would have thought you would have a place out in your area (with in 100 miles) where you could go and open it up , all the way to the red line in 5th gear. The stretch I've opened mine up is only 2&1/2 miles long, it reached the 186 MPH from 60 MPH in less than 1&1/2 miles. I'm going to try to find a place somewhere close to me this summer that I can legally open it up just to see if it will hit the 200 MPH mark, the 1" taller tire's may help to get me there. I know it's been said that the SRT6 would redline before it reached 200 MPH, but at 186 my tach was hitting 5,600 to 5,700 RPM if I remember correctly (at that speed I was just giving it quick glances), I've only got 14 more MPH to get there.
