Re: Spreadsheet for Gear Ratio Calculations (The Dude)
Yeah, I figured that's what it had to be. But then the equation is the same as (RPM*Displacement*.85)/3456. Is that how it's meant to be? [I updated to reflect this change, same URL.]
Anything else to add to it?
If we get ahold of the equations and drag coefficients for different cars we could get aerodynamics and such, that would be cool to have onhand.

I am looking for a simple formula that will give density altitude given the physical altitude, temperature, humidity and altimeter. That's going to be tough, though.

Found this site - all kinds of good stuff, great calculators for much of the stuff discussed here.
