Listers,
Last week, Dan Masters kindly shared an excel spreadsheet with us
that calculates MPH and RPM for different tire sizes. It is et up
for general purpose 4 speed gearboxes. I decided to customize it
a little and focus it in on Triumphs.
I added in OD calculations and reverse and grayed out the RPMs
above 6000. The default gear ratios are for a TR2-TR4A with an
A-type OD and the default tire is a 165/80-15.
It can be opened or copied at:
