Скачать или смотреть How Much Horsepower Does a Turbo Add

The horsepower gain from adding a turbocharger isn’t a fixed number—it depends on factors like engine size, baseline output, boost pressure, internal strength, fuel quality, tuning, turbo size, and environmental conditions. A turbo works by using exhaust energy to drive a compressor that forces more air into the engine, increasing oxygen for combustion and thereby boosting torque and horsepower. In practice, mild setups on small economy engines can add 40–70 hp, moderate upgrades on mid-sized gasoline engines can yield 80–150 hp, and high-performance builds with large turbos and strong internals can achieve 200–500+ hp, while diesel truck upgrades often see 150–400+ hp with major torque gains. While stock turbos prioritize reliability and drivability, aftermarket systems can push power much higher with proper supporting mods. A rough estimation formula relates horsepower to boost pressure, but real-world results are usually 10–30% lower due to heat and inefficiencies, making it essential to treat the turbo, engine, fuel, and tuning as one integrated system.
