“There are plenty of people who purchase a car and drive it for twelve years or more,” Jake Fisher, director of auto testing for Consumer Reports, told Design News. “And the jury is still out on how these small-displacement turbos will do at 150,000 or 200,000 miles.”
A turbocharger is a forced induction system. It compresses air flowing into the engine. The advantage of compressing the air is that it lets the engine squeeze about 50 percent more air into each cylinder. The turbine spins at up to 150,000 rotations per minute (RPM), which is faster than most engines can go.
Turbocharged engines will require more frequent oil changes and fresh spark plugs, though turbo engines typically don't require additional service compared to naturally aspirated engines.
One way to make a car go faster is to add more cylinders. Another option is to use a turbocharger, which forces more air into the cylinders each second so they can burn fuel at a faster rate. A turbocharger is a simple, relatively cheap, extra bit of kit that can get more power from the same engine!
A turbo can significantly boost an engine's horsepower without significantly increasing its weight, which is the huge benefit that makes turbos so popular! In order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump.
A “normal” engine, which is naturally aspirated, simply sucks in the air it can get via the air intake. A turbocharged engine is equipped not only with the regular air intake, but a turbine device that is driven by exhaust gasses which then spins it and forces more air compressed into the engine.
6 Ways to Protect Your Turbo Engine
- Regular Oil Maintenance.
- Warm Up the Engine.
- Don't Overstep the Limits of the Turbo when Cruising.
- Use Your Gears to Overtake.
- Let the Engine Cool After Driving.
- Don't Blip the Throttle Before Turning the Engine Off.
A turbo is more efficient than a supercharger since your engine does not need to work harder to power the turbo. Because a turbo is not connected directly to the engine, it can spin much faster than a supercharger.
Oil requirement: turbochargers get very hot and often tap into the engine's oil supply. This calls for additional plumbing, and is more demanding on the engine oil. Superchargers typically do not require engine oil lubrication.
Turbo engines tend to have more problems in many cars, although there are turbocharged engines that are reliable. A turbocharged engine has more components than a naturally-aspirated (non-turbo) motor. A turbocharger itself is not uncommon to fail.
The turbocharger is a air pump that increases the flow of air to a fast revving engine to be able to burn more gasoline than with normal air pressure. If you have a turbo charged engine but drive gently so it doesn't need to pump the additional air and gasoline then you won't use more fuel.
The two major
advantages of a
turbocharged engine are greater power density and increased fuel efficiency.
Cons:
- Fuel economy can tank when driven aggressively.
- May require premium fuel.
- Can inflate repair costs.
The turbocharger itself can also introduce a whistling noise to the intake, not unlike a jet engine. The turbo has a similar effect on exhaust systems, where the exhaust-side impeller disrupts the exhaust flow by creating an extra gate for the sound to have to flow through.
Engines with high compression ratios or turbochargers often require high octane fuel found in premium gas for optimal performance and fuel efficiency. However, the majority of cars on the road today are optimized to run on regular gas.
The purpose of a turbocharger is to increase the power output of an engine by supplying compressed air to the engine intake manifold so increased fuel can be utilised for combustion. The purpose of the altitude compensator is to maintain consistent power output and efficiency of an engine operating at all altitudes.
A turbocharger is basically a pump that forces more air, and therefore more oxygen, into the fuel-air mixture an engine burns. Up until a few years ago, turbos were added to an engine to produce more power. The turbo itself doesn't save gas, but using the smaller engine does.
The difference comes from the increased cooling requirements for the turbo engine. The extra strain of towing more than 3.5 tons would put the turbo engine at risk of overheating. So if you're focused on maximizing your pulling power in a full-size pickup, we recommend the V6 engine over the 4-cylinder turbo engine.
2. Turbos Reduce the Lifespan of an Engine. However, a properly implemented turbo pushing enough PSI through a motor to produce respectable levels of power won't strain a motor any more than idling in traffic will.

I suspect a straight 4 truck engine would be more reliable still but it wouldn't fit under the cab so easily or provide as smooth power delivery. However the reason four cylinder engines are so popular in cars is that they provide enough reliability, power and smoothness for their price.
Your turbocharger is a turbine/fan device driven by the engine's exhaust gases, devised to boost the pressure of the incoming air into the engine. The vehicle can run without an efficiently functioning turbocharger, but it will perform poorly, and your decision could possibly have dramatic repercussions.
Compared to a naturally aspirated engine, there is significantly more pressure in the combustion chamber for a turbocharged engine. While the engine makes more power this way, it also uses a lot more fuel, which brings down efficiency.
In the end, the power-to-weight ratio is much better for a turbocharged engine compared to a naturally aspirated one. A naturally aspirated engine is an internal combustion engine in which the air intake relies solely on atmospheric pressure, which is the exact opposite of the force induction turbocharged engines use.
Usually when a turbo fails the pieces go into the intercooler along with a good amount of engine lube oil. The engine can actually run on this spilled oil and "run away." If you have a failure, remove the intercooler and ALL intake system tubes; this includes the airbox, filter housing and associated tubes.
The result is a much more reliable system than previous generation had. Why has Volkswagen turbocharged most engines? As we've said, power and efficiency come down to how much air you can pull into the engine to mix with fuel for combustion. Aside from using a turbocharger, there are two ways in which this is done.
Undoubtedly the most common reason for turbocharger failures is the presence of problems in engine lubrication. Simply put, if you have either oil contamination or even oil starvation, then this can lead to turbo failure. This assembly is where the turbine wheels and the turbo compressor are mounted.
Yes you can typically put a turbo on any car if there is the space to do it. In fact it is a fairly common modification on many older cars (cough* Honda Civics). It was the cheapest and fastest way to increase the power output of your car by as much as 50 hp, with minimal changes to the car.
The average cost for a turbocharger assembly replacement is between $4,116 and $4,463. Labor costs are estimated between $1323 and $1670 while parts are priced at $2793.
