Yup, about as close as we can get here in the states, although, if I remember correctly, about 10 years ago they did set a statewide interstate speed limit of 75 mph. Doesn't stop me from cruising at 100 when I'm roaming around out there though, and I've never been stopped or even seen a police officer sitting and shooting radar like we have all over the place here out East.

Not to take this thread off subject, but 163 (or 170) seems like it's a pretty low estimate for top speed. I had mine up to 150 and it barely shifted into 5th before it shut down at 155 (well, my speedo read about 158-159 when it shut down, so maybe it's off compared to what the computer sees for speed). By my calculations based on RPM at 155 where mine shut down, it should hit 181 just like SLK32Germany posted.

Oh, and for the record, we were cruising at 80 mph when I punched it and it took almost a full mile to get to 155, so I highly doubt you could get anywhere near a stock SRT6's top speed in a standing mile.
