top speed math

[Neal3000]

can someone maybe who has one of them Kansass educations tell me what the formula is for figuring out your rigs potential top speed?

is this it?

MPH = (RPM * Tire Diameter) / (gear ratio * 336)

even better just plug your junk in and this will spit it out by gear

that or go to grimmjeeper.com and click on his gear calculator.... it allows for a side bye side comparison, so you can fiddle with your gear ratio a little easier
