Try this out, I put together an excel document with Legend Specs, Transmission gear ratios and tire/wheel sizes, a displacement calculator, and a Legend VIN analyzer.
Here's how you use the pages:
Specs - straight from the website/documentation. Just read them.
Trans/Wheels - plug in different gear ratios or final drives, plug in different wheel and tire combinations, and it will calculate your topspeeds in each gear, etc. It also shows how far off of stock various wheel/tire sizes are.
Displacement - plug in various bore and stroke measurements to determine displacement. Currently shows Legend, RL, and NSX.
Horsepower Estimator - plug in your vehicle weight and trap-speed or quarter mile time.
VIN analyzer - just copy/paste a VIN into the red cell and it will break it down for you.
NO MACROS, just functions. If excel asks you about macro security, you've probably got a virus.
