I made up a simple Excel spreadsheet to calculate:

- tire revolutions per mile
- driveshaft revolutions per mile
- VVS Pulses Per mile
- engine rpm in 1:1 ratio
- engine rpm in overdrive

based on:

- Tire diameter
- axle ratio
- VVS Pulse Per revolution
- overdrive ratio


however when I tried to attach the file, there isn't an option

Upload Error
Axle,Tranny,RPM Calculator.xls: Invalid File

 

the file extention isnt in the database or not in VB, thus throwing you the error of being invalid

 

Zip the file, then it will let you attach it.

 

^^ bingo, winner winner! zip it and post it!
