The video is from the YouTube show "Mighty Car Mods" and features the hosts testing an electric supercharger from eBay on a 1990s Daihatsu Charade. The supercharger claims to add 50 horsepower to the car's engine, but the hosts are skeptical. They first test the car's stock engine on a dyno, which produces 24.4 kilowatts of power. They then install the electric supercharger, but after several runs, it only adds 2 kilowatts of power. The hosts suspect that the supercharger is adding load to the electrical system, which is actually decreasing the car's power. They then try powering the supercharger with an external battery, but still see no significant power gains. The hosts conclude that the electric supercharger is not effective and is essentially just a glorified computer fan. However, they do see some power gains when they use a homemade "twin leaf blower" system, which adds 27 kilowatts of power. The hosts attribute this to the leaf blowers' ability to move air, but note that they are not compressing air like a traditional turbocharger.
Here are the key facts extracted from the text:
1. The hosts purchased an electric supercharger from eBay for $300.
2. The electric supercharger claims to add 50 horsepower to a stock car.
3. The hosts tested the electric supercharger on a 1-liter, 3-cylinder Daihatsu Charade.
4. The car's original power output was 24.4 kilowatts.
5. The electric supercharger did not increase the car's power output significantly.
6. The hosts also tested a homemade twin-leaf blower system, which increased the car's power output to 27.6 kilowatts.
7. The twin-leaf blower system was made from AG pipe, a T-piece, and two leaf blowers.
8. The twin-leaf blower system was sealed with gaff tape to ensure a tight seal.
9. The hosts concluded that the electric supercharger does not work and is not a true supercharger.
10. The twin-leaf blower system, while not a true supercharger, did increase the car's power output slightly.
11. The hosts attributed the increase in power output to the additional airflow provided by the leaf blowers.
12. The hosts noted that the twin-leaf blower system is not a practical or efficient way to increase power output.
13. The hosts concluded that true superchargers, such as turbos, work in a different way and are much more efficient at compressing air and increasing power output.
