Hi Opendro, like Shan2nu had mentioned just considering drive-line gearing & wheel dimensions would result in top-speeds you can't achieve in real life. You could do it on a chassis dyno though, I guess.

The thing that stops you is aerodynamic drag, which is why if you sky-dive you'll not top 196 Kmph (terminal velocity). Plus, you'll have to contend with rolling resistance. Aero Drag is function of your car's drag coefficient (Cd), frontal area, air density & finally the square of your speed.

Rolling resistance, on the other hand, is a function of coefficient of rolling resistance & the weight of your car.

Cd values are usually included in a car's specifications, frontal area is not...
