The only way you can get that kind of speed is have a drive clutch the size of a car tire and the HP to turn it, turn 15,000 RPMs(not recomended), have 35" rear tires(also not recommended), do the evil Kenevil stunt off the side of the Grand Canyon(highly not recommended, but worth watching), or finally, strap a JEDO rocket assist booster to the back of your buggy like the guy did from the "Darwin Awards" a few years back(also highly recommended for this knob and worth watching too).
