I’ve always hear it when i’m watching about racing cars, i’m a farn of cars but i dont know about naturally aspirated and supercharged engines.

An internal combustion engine is basically an air pump, it sucks air in and we mix that with fuel and the two combined is how we get the fire to drive the engine.
A naturally aspirated engine is just pumping the air by itself with its pistons- every time the piston goes “down” and the valve opens it sucks in air, just like your lungs. The air is at normal atmospheric pressure
A supercharger is a separate air compressor which is driven by the engine, which means that when the air reaches the engine, it’s under more pressure than normal air. It still breathes in almost the same but there is more air in each breath.
(A turbocharger also adds a separate air compressor which is driven by the exhaust gas instead of the engine, and pushes in more air, it’s a different method but the same idea, squishing the air means each gulp has more air in it.)
(nitrous is similar but instead of compressing the air so you get more per gulp, it changes the mixture of the air so there’s more oxygen per gulp. Like putting more whisky in your drink, rather than drinking more whisky-and-coke)
More air means more fuel means bigger kabooms
