Turbo basically just forces more air into the combustion chamber. It does that by spinning a turbine with exhaust gases, which turns a compressor that raises the intake pressure. Typical street turbos boost between 10 and 20 psi, and you can get roughly 10 hp per psi of boost if the engine is tuned for it. That extra air lets you burn more fuel, so the engine produces more power and the turbo feels like it’s fighting the natural aspiration. It’s not a rebel—just a physics‑based way to squeeze more performance out of the same engine block.
