    Tranny calculator

    Hello!

    I was comparing a ZF tranny to a getrag 260 with an excel sheet and Graph. With my tire and and diff, I found out that I would probably prefer a getrag 260! Not that much more rev drop. The gear are well spreaded!

    Here is my calculator (sorry its big but I wanted you all to see correctly)




    If any one of you has a ftp, I could send it any then make it available for everybody...

    edit: I could put it in MPH if there is an interest

    Cheers

                  I made a similar chart for deciding what differential would be right for me. I have an input for a single gear spot and several differential gearings, so you can set it up for anything. It comes out in MPH though instead of KMH.

                  If anybody is interested in having the excel file to play with, let me know.
