What are the damages of installing a turbocharger to the engine?
3 Answers
After turbocharging, the pressure and temperature during engine operation significantly increase, resulting in a shorter lifespan compared to naturally aspirated engines of the same displacement. Additionally, mechanical and lubrication performance will be affected. The advantage is that it increases the engine's air intake, thereby enhancing the engine's power and torque, allowing for greater power output after turbocharging. After installing a turbocharger, an engine's maximum power can increase by 40% or even more compared to when it was not equipped with a turbocharger. Below are some details about turbocharged engines: 1. Working Principle: Generally, turbocharging is indeed suitable for long-distance driving, similar to naturally aspirated engines, because long-distance driving involves higher and more consistent speeds, keeping the turbocharger engaged for extended periods, which can be more fuel-efficient compared to naturally aspirated engines. The main difference between turbocharged and naturally aspirated engines lies in the presence of the turbocharger. For a given engine displacement, the most effective way to increase output power is to supply more fuel for combustion. 2. Precautions: Improper driving can severely impact the lifespan of both the turbocharger and the engine.
I personally experienced the consequences of adding a turbocharger, and the engine suffered significant damage. The sudden increase in intake pressure after turbocharging was beyond the original factory engine design, and internal components couldn't withstand the high temperature and pressure. My car quickly developed issues like piston ring wear and severe oil leaks. The cooling system couldn't keep up, leading to cylinder overheating and knocking. The repairs were extremely expensive, costing an extra few thousand dollars just to replace the radiator. Playing around like this long-term cuts the engine lifespan by more than half, and you have to frequently maintain the fuel and lubrication systems, otherwise it could break down on the roadside at any moment. It's really not as worry-free or safe as factory-turbocharged models.
From an economic perspective, adding a turbocharger can be a major financial burden. The increased engine load after turbocharging makes original components like bearings and seals more prone to damage. I personally experienced overheating due to not upgrading the cooling system, requiring three repairs before it functioned properly. Maintenance costs are significantly higher, necessitating frequent oil changes with high-quality lubricants and regular checks on turbo bearings. If issues arise, major repairs can cost upwards of ten thousand, and it also negatively impacts resale value. Overall, the enjoyment of modification doesn't outweigh the high expenses and reduced reliability risks. Before installation, always conduct a thorough evaluation and reinforcement to avoid engine damage that outweighs the benefits.
