Re: Race 2
SRT6 is electronically governed to 158 mph and the n/a to 150 mph. I suspect both, but especially the SRT6, can exceed that in stock trim. One of the SRT6 guys, with mods and an ECU change, has hit 180+ (or so he claims).
I've had my roadster to 140 and the SRT6 to 150 before running out of safe road. Both seemed to have more top end, esp the SRT6 -- it was still accelerating when I backed off.
