CheshireCat Posted August 15, 2017 Share Posted August 15, 2017 I am looking to move from std 5 speed to std 6 speed gearbox with a 3.9 diff and would like to know how this translates to speed in each gear.i have looked in the archives and older links no longer work on the threads i was looking at. Please can someone point me in the right directtion of a basic gear calculator for a caterham or tables of information that will give me the gear speeds ? Thanks Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted August 15, 2017 Member Share Posted August 15, 2017 I don't know an online calculator that's preloaded with the data. You could try something generic like this, although it's in the wrong units. You'd then also need the gear ratios, both 5 speed and 6 speed, and do you know the size of the tyres?Jonathan Link to comment Share on other sites More sharing options...
oilyhands Posted August 15, 2017 Share Posted August 15, 2017 There are several gear speed calculators on the Web, there is a DOS based one on my website pre loaded with several of the popular gear sets.Oily Link to comment Share on other sites More sharing options...
