Re: I need help with my speedo gear
from the info you've given, we can figure out your tire diameter. i can't remember the formula for that right off the top of my head, but it's pretty easy.
then, we need to know what your gear ratio is.
then, we can figure out what your final drive ratio is.
then, we need to know what kind of tranny you have, and what drive and driven gears are already in it. this will tell us what gear(s) you need to make your speedo right.
there are a few handy websites out there that can help you out with all this, or you can go buy a neat book called "The Automotive Math Handbook"- or something like that- it is a really useful book.
you don't plan sincerity.
you have to make it up on the spot.
wanna hear about 20 years ago when i was too smart to know any better?
