Can A Turbocharged Go-Kart Outrun A Real Car? | MythBusters
The MythBusters tackle an urban myth about a jet-powered go-kart made from an oil drum, exploring whether it can achieve crazy speeds or if it's just hot air.
Watch on YouTube ↗Key takeaways
- 🏎️The myth involves strapping a 55-gallon oil drum filled with jet fuel to a go-kart for a high-speed ride.00:34
- 🚀A 'woosh rocket' uses expanding gases from ignited vapor to create thrust, a principle the myth attempts to supersize.01:40
- ❌Initial full-scale tests with the barrel go-kart failed to ignite the methanol fuel, resulting in no movement.03:36
- 🧪Small-scale tests revealed that a lower fuel-to-air ratio (0.1% vapor) produced the most thrust, doubling the distance traveled.06:38
- 🛠️Modifications like an aerated fuel system, a cone shape, and a nozzle significantly improved thrust in small-scale tests, propelling the barrel 15 feet.10:15
- 💡The modified design evolved from a simple woosh rocket to a pulse jet, which provides continuous thrust through repeated combustion cycles.11:55
