I did quite a bit over 110 indicated, but I don't for a minute believe this speedo is very accurate. 60 indicated, is really"radar"65. I'm sure it gets more wacked the faster you go (stock tires). 110 indicated, felt more like 100 or so...who knows? Never have repeated the stunt because the 'stones scare me at that speed, and the car was never made for that sort of thing, and does not feel that it is entirely comfortable with being treated in such a fashion. High speed is not it's thing, but I've never hit a rev limiter....go figure. Wayne
