A turbocharged engine has more components than a naturally-aspirated (non-turbo) motor. … That said, there are many turbo engines that can last long. Take, for example, the turbodiesel in the Mark IV Volkswagen Golf / Jetta (from early 2000’s). Many of them are going well past 200K miles with good maintenance.
How many miles do Turbos last?
Turbos are designed to last the lifetime of the vehicle (or around 150,000 miles); however, it’s possible for them to wear out over time depending on how hard you drive the car and the original build quality of the turbo.
Which is better turbo or naturally aspirated?
Because turbocharged engines can cause lag – when the turbine is spooling up to match the throttle response opening – naturally aspirated engines are superior at delivering consistent power levels throughout the engine’s entire powerband.
Do naturally aspirated engines last longer?
Do naturally aspirated engines last longer? – Quora. Generally yes. Some of these turbo charged 4 cylinder engines start to burn oil as early as 60K miles. Chevrolet Equinox has excessive oil consumption.
Do naturally aspirated engines last longer than turbos?
The benefit of a naturally aspirated engine is that they are in general more reliable than forced induction engines, or engines that rely on a turbo or supercharger. The big drawback is that to have a high-output naturally aspirated car usually means having a large, heavy and petrol guzzling engine.
Do turbos shorten engine life?
2. Turbos Reduce the Lifespan of an Engine. One of the most common turbo myths is that running boost will damage your engine over time. … 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.
What is the disadvantage of turbo engine?
Smaller engines use less fuel, but being turbocharged adds pressure, which can lead to higher temps and engine knock, damaging the engine. To avoid this, you have to have a lower compression ratio. Thermal efficiency and compression ratio are directly correlated.
Why is a turbo engine better than aspirated engine?
Now if both the engines were similar NA would definitely do better but turbo on smaller engines gives the same power as bigger NA engines with less fuel. Thus Turbocharger has better Fuel efficiency for the same engine output and they are better of being used in smaller engines.
What are the disadvantages of supercharging?
Disadvantages of supercharging
- Increased detonation tendency in SI engines.
- Increased thermal stress.
- Increased heat loss due to increased turbulence.
- Increased gas loading.
- Increased cooling requirements of the engine.
Why do naturally aspirated engines rev higher?
NA engines must rev higher to produce a similar power output as a turbo engine does at lower revs. High RPM is not something that is good for an engine in terms of wear, or fuel economy. And the stresses on the engine parts are greater with high RPM than with increased manifold pressure.
Why do naturally aspirated engines sound better?
Larger displacement engines sound better, they deliver power in a more linear fashion which some people prefer, and having no turbine in the way of the exhaust means a naturally aspirated engine likely sounds better than a turbocharged engine of the same cylinder count/displacement.
Can a naturally aspirated engine be turbocharged?
In short, although you can theoretically add a turbocharger to almost any naturally-aspirated engine, it’s not a plug-and-play process.
Does turbo spin at idle?
Turbos spin whenever the engine is running, although not fast enough at Idle to produce enough air flow to be called as “boost”.
