Turbocharging can indeed increase the power of the engine, but it has many shortcomings, the most obvious of which is the lagging response of the power output. Let’s take a look at the working principle of turbocharging above. That is, the inertia of the impeller is slow to respond to sudden changes in the throttle. That is to say, from when you step on the accelerator to increase the horsepower, to the rotation of the impeller, more air pressure will be exerted. There is a time difference between getting more power into the engine, and this time is not short. Generally, the improved turbocharging takes at least 2 seconds to increase or decrease the power output of the engine. If you want to accelerate suddenly, you will feel as if you can't get up to speed in an instant.

With the advancement of technology, although various manufacturers that use turbocharging are improving turbocharging technology, due to design principles, a car with a turbocharger installed feels like a large-displacement car when driving. Somewhat surprised. For example, we bought a 1.8T turbocharged car. In actual driving, the acceleration is definitely not as good as 2.4L, but as long as the waiting period is passed, 1.8T power will also rush up, so if you pursue In terms of driving experience, turbocharged engines are not suitable for you. Turbochargers are especially useful if you are running at high speeds.

If you often drive in the city, then it is really necessary to consider whether you need turbocharging, because turbocharging is not always activated. In fact, in daily driving, turbocharging has little or no chance to start. Use, which affects the daily performance of turbocharged engines. Take Subaru Impreza’s turbocharger as an example. Its start-up is about 3500 rpm, and the most obvious power output point is about 4000 rpm. At this time, there will be a feeling of secondary acceleration, and it will continue until 6000 rpm. Even higher. In general, our shifts in city driving are actually only between 2000-3000. The estimated speed of 5th gear can be up to 3,500 rpm. The estimated speed is over 120. That is to say, unless you deliberately stay in a low gear, you will not exceed the speed of 120 kilometers per hour. The turbocharger can't start at all. Without a turbocharged start, your 1.8T is actually just a 1.8-powered car. The 2.4 power can only be your psychological function. In addition, turbocharging also has maintenance problems. Take Bora’s 1.8T as an example, the turbo will be replaced at about 60,000 kilometers. Although the number of times is not too high, it adds to the invisibility of one’s own car. Maintenance fees, this is particularly noteworthy for car owners whose economic environment is not particularly good.
