As man explores options for alternate fuels and new ideas to haul heavy objects and himself across long distances, it’s important to remember one of the key aspects of the human dream, namely going really really fast. Like this little car!
The video in question is up above, so give it a watch before you keep reading. And pay close attention to the sign tracking speed, because watching the numbers go up is almost as entertaining as hearing the car’s engine buzz louder and louder. Of course, by the end it sounds like Satan’s hornet swarm, but that’s the price you pay with motors that run on nitro.
Little Car, Big Speed
So how did they pull off 200mph with a car you can use as a roller skate? To start with, miniature racing cars with combustion engines generally use nitromethane, shortened to “nitro”, which, by volume, lets you cram nine times as much fuel into an engine to burn, giving these little cars an excessive amount of power in the first place.
Secondly, they make use of that ever-handy concept of physics, centrifugal force. The car is tethered to a stake in the middle of the course, and, as it goes around the track, the force gives it more speed to go whipping around the track. Until, of course, you get the results that you see in the video.
Probably Not Coming To A Race Track Near You
That said, this probably won’t be scaled up; although there are full-size racing vehicles that use nitro, the centrifugal force would be a bit rough on human beings if it were scaled up. But it’s a neat demonstration of how to get a lot of speed out of a tiny little car. Just nobody tell Joerg Sprave, or we might have a world-ending slingshot.
