My stock 06' R/T R&T topped out at 142MPH. With intake and Superchips I topped out at about 158MPH (limited by only the wind). With my current mods less the nitrous I've hit about 163MPH.
I'm afraid to use the nitrous at 160MPH because my tires are rated for 149MPH, I'm sure they would be all right, but its hard to find enough open highway in the L.A. area to hit 170+ MPH.
