Speedometer Problometer
So I always have questioned the accuracy of my Speedometer, and other people have told me that I was driving 50mph and my speedo said 55. At 60 they tell me I'm driving 55. But I followed my Mom in her caliber (and I know that speedo is incredibly accurate, from passing a speed sign). and she went 55 and mine said 55. So I'm beginning to question how accurate it is. I've passed one of those speed signs one time, and my speedo said 45 but the sign said I was doing 43. I'm guessing it's about 5mph off at 60.
Question is, how do I test this? I'm just glad its overrating my speed, and not underrating it. I know that the best way would probably be take it to a dyno, which I have no idea where one would be. And how much would it cost to dyno the thing?
