Well I made one to make the tables above. Just plug in rear gear ratio, and tire size. You can change trans ratios to see the difference. Happy to share with you if you want to mess around with it.
Yep, I've got an excel spreadsheet (actually several) that gives me the splits, multiplications and RPM's at speed, etc. Thanks though!
I was complaining that cutting and pasting the data here makes for a mess. On ChallengerTalk, clipping from excel and pasting in the post makes a cell based entry similar to excel. Makes for a much nice way to post info.
At the same time, I guess I didn't really try it this time, and your post looks great. So maybe it is an option now and I should have tried it.
