It depends on the gearing. If you have a higher gearing, then it will go faster (with the tradeoff being less power). If you have a lower gearing, then it will go slower but have more power.
you can take off the govonor of the motor (google it) and you can also take the exust pipe/muffler off for more air flow giving you more power
try tightning the fuel intage (screw under air intake) pour a lil gas into air intake or even better starter fluid. make sure your spark plug is gaped correctly (.030), make sure your clutch is on.

This question cannot be answered with this information. There are too many variables like gear ratios, weight of the vehicle, etc. 5hp push lawn mower = 0mph. 5hp go gart = what, maybe 30mph 5hp engine in my car = not very fast!
