Does Higher Boost Pressure Mean More Horsepower?

There is no significant difference in the size of automotive turbochargers. A turbocharged engine is an engine equipped with a turbocharger, which works by utilizing the inertial force of exhaust gases expelled by the engine to drive a turbine in the turbine chamber. The turbine, in turn, drives a coaxial impeller, which spins at high speed to force more air into the intake manifold, thereby improving the engine's combustion efficiency. Relevant information about turbochargers is as follows: 1. Introduction: A turbocharger is essentially an air compressor that increases air intake by compressing air. 2. Working Principle: It uses the inertial force of exhaust gases expelled by the engine to drive a turbine in the turbine chamber. The turbine then drives a coaxial impeller, which compresses air delivered from the air filter pipe, pressurizing it before it enters the cylinders. As the engine speed increases, the exhaust gas expulsion speed and turbine speed also increase synchronously, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable the combustion of more fuel, and by adjusting the fuel quantity and engine speed accordingly, the engine's output power can be increased.
I used to think that higher turbo pressure would instantly boost horsepower, since more boost means the engine can suck in more air, burn more fuel, and naturally increase power. But it turns out you can't just crank it up arbitrarily—the engine has its limits. Back when I was driving a performance car, I tried increasing the turbo pressure from 10 psi to 15 psi. The acceleration did feel punchier at first, but after a few high-speed runs, the engine started knocking with a pinging sound, and the cooling system couldn't handle the heat. It ended up costing me hundreds in repairs. If you push the boost too high, not only does fuel consumption skyrocket, but you also risk shortening the turbo's lifespan or even wrecking the entire engine. I've learned my lesson now—before any mods, I make sure to use high-quality fuel and upgrade the cooling system. Every pressure adjustment is done within safe limits. Regular boost pressure checks let me enjoy a little extra thrill without the constant worry.
