This is a quick hack based on Rob Glover's Gear Calculator. His is much better, I only wrote this one because Netscape wont print the output of a javascript document.write().

I also wanted to see three side by side, and the ability to set the text size for printing. The cells turned black are supposed to show what speeds rpm/speed you are hitting in a WOT run, showing where you land on a downshift. If you want a tire diameter calculator or have any other suggestions please email
