For engine speed, carefully roll the van one wheel revolution in
inches. Then divide by 12 to get feet. Divide that number into
5280 and you will have wheel revs per mile.

Now, go to www.volksweb.relitech.com/helmet/gearbox.htm and find
your transmission code and ratios.

Now, pick an engine speed, gear ratio, your final drive ratio, and
your tire revs per mile. Now take engine rpm/final drive/gear
ratio/revs per mile x 60. This will tell you road speed at that
given rpm. Do it for each rpm you are curious about. Make a little
chart and tape it on your dash.
