Excel Tranny Gear Ratio Calculator Inside!
 

I found this spreadsheet recently and had to share it for all those in wonderment of what this or that tranny swap will do for your car. It also was such features as custom tire/wheel size, side-by-side comparison of two different transmission ratios, X RPM @ 65 MPH, and a complete listing of every speed at every realistically possible RPM (@ 100 RPM increments) an engine can produce, based on your ratios. Here are instructions:

1. Simply go to the link below, click
2. Scroll down to the "Si Vs. 49HF" file in the bottom left corner and find "add spreadsheet to cart", click
3. Go over to the pull down menu that reads "cart actions" and select "download to Zip"
4. Click "Go"
5. Download, unzip, read, modify etc

Enjoy! Mak
