<I haven't had mine up that high...yet :)
I have seen 135+ at the end of the straight at SIR (admittedly with
instructor driving--my own?  you're not supposed to look when you're the
driver :)

I do suspect the factory speedometer, though...my experience says they are
optimisitic, and the error seems to grow with higher speeds.  > snip


My speedo seems to be pretty linear in regards to rpms. This time, I could not 
see the speedo behind my hand, but did glance at the tach. 
I seem to get 25+mph/1000 rpm in 5th
2000 = ~52 on speedo
3000 = ~77
4000 = ~104 (error starting to creep in)
5000 = ~129 (still pretty close)

Anyone else see about these speeds vs rpms?

I spent a lot of time between 4k and 5k this trip. 

Haven't looked at the speedo for any higher rpms. But it is pretty linear. And 
I do believe 6000 is above 150. Whatever it was, the fence posts were going by 
mighty fast  :-) And it felt like there was still room for few more  :-)
