First of all, every one of those speed trap things that the police put up that show your speed read 5mph higher than my speedo does. Every one of them, exactly 5, no matter the speed. Also, I have clocked against friends and my speedo reads a consistent 4-6 higher than theirs. Now, my car doesn't pull (to me) like it has gears in it. I bought the car used and have no reason to believe that the gears are anything but the stock 3.27..
I know they are not anything 100% accurate to go by, but I found
these numbers and my rpms do not match any speeds of the chart
I have the stock 17in rims, with 245/45R17 H rated tires.
On my speedo (that I believe reads 5 high), I redline 1st at 35mph, 2nd at 60mph, 3rd at 90mph, 4th at 120mph and 5th I don't know. Another rpm/speed combo that I remember about my car is that at 2000 rpm in 5th gear I am going 60mph via my *innacurate* speedo.
What gives?
