[DML] Re: Speedo gear rpm.

["Elvis" <elvisnocita@xxxxxx>]

Almost, Tom, almost :-)

100kph -> 1000rpm
100kph = 27.78 m/s
1000rpm = 16,67 revolutions per second.

this means one revolution = 27.78m/s / 16.67r/s = 1,667 meters :-)
(for the non-metric guys - it's a lot of feet :-)  )

the 1-2mph offset that I got is pretty good, you
probably won't find a more precise speedo out there.

The one I have now was converted to metric and recalibrated 
by someone (a shop ?) and it is off by 7kph @ 170kph 
which is they way the normally calibrate those speedos.
If I ever take it out again I may recalibrate it :-)

And because it is so much fun, the drivers side window 
drive failed right after I installed the speedo :-(
Hey Ken, are we going to have engineers from back then at 
the show ? I'd like to ask them how many Guiness they had to 
drink before they were allowed to develop that stuff....
