ELI5: Antilag systems in turbo cars.
gpt
A turbocharger works by using air pressure from the exhaust to compress the fuel/air mixture going into the engine increasing engine performance. Unfortunately, there isn't always enough exhaust pressure to run the turbo at the beginning of the acceleration, so there is a delay (lag) between when the accelerator is pushed and when the turbocharger starts doing its work.

Antilag devices solve this by increasing the exhaust pressure even when the engine isn't doing much work. The essence of how these things work is by burning fuel outside of the engine and sending that exhaust through the turbocharger.
