All this talking want me to go fast as well....... Im usually good in math but I dont get teh formula that relates KV, RPM, volts and MPH, also how the motor relates to all this......

I have a 7XL on 16 cells right now, what RPM am I getting? What RPM would I get if I go 8XL on 20cells? or if I just go 20cells on my 7XL......... and lastly what kind of speed am I looking at with a 8XL on 20cells using 1/8 diffs and 51/?? spur/pinion?
