Final drive calculation.

[Bean]

later than promised but here goes:
use this link http://goo.gl/AOqKQy it should take you to an online calculator with graphs and all the data already in it. If you hover the mouse over the top two lines at different points it will show the corresponding speed and rpm to be expected.

If you want to try different final gears just enter the new number in the representing field and hit the lower right calculate button again

PS: the upper table also lists shift points for each gear. This is the rpm you'll have when shifting up to that particular gear at redline from the previous.
