Can a turbo hurt your engine?

Smaller engines use less fuel, but being turbocharged adds pressure, which can lead to higher temps and engine knock, damaging the engine. … To reduce the temperature, you have to dump more fuel to protect the engine with a higher fuel to air ratio, and your fuel economy goes out the window.

Do turbos shorten engine life?

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 are the disadvantages of a turbocharged engine?

A turbocharger used without an intercooler can create extremely high heat in the engine compartment of the vehicle. This additional heat can lead to overheating breakdowns, melting of critical plastic engine components and fires. Using an intercooler mitigates this problem, but is an expensive addition to the system.

Do turbos mess up your car?

Does adding a turbocharger to your car ruin the engine? – Quora. Yes and no, depends on the engine. Most factory naturally aspirated (no turbo/ supercharger) have a really hight compression ratio to be able to extract as much power/efficiency out of an engine without adding boost.

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.

Does turbo use more fuel?

Consumer Reports, for example, concluded that downsized, turbocharged engines typically achieve worse mileage than larger engines without turbochargers. In their tests, Ecoboost Ford Fusions using turbocharged, four-cylinder engines burned more fuel than their larger, naturally-aspirated counterparts.

What RPM do turbos kick in?

You Spin Me Right Round (Like a Turbo, Baby): The turbine in a typical car turbocharger has to spin incredibly quickly. While your car’s engine revs, at cruise, at around 2,000 rpm, a turbo’s turbine can reach rotational speeds of more than 280,000 rpm.

Why do turbos rev lower?

A turbo’s job is to pressurize air, thus forcing more air into the engine. For most street cars, low-end responsiveness is typically desirable. This means most turbochargers are generally smaller and have lower rotational inertia-this allows them to spin up and produce boost (pressure) more quickly.

Why is lugging an engine bad?

At the most basic level, lugging your engine doesn’t make much sense because it puts your engine at a disadvantage. That means it has to work harder to do the same amount of work. But that also means it runs less efficiently, increases engine temperature, and can even cause issues with the engine’s timing.

Is supercharger safer than turbo?

Superchargers are arguably more reliable than turbochargers. They’re easy to install and maintain. They’re louder than turbochargers—they enhance the RPMs by a considerable amount—and they’re also more common as a result.

Does turbo affect top speed?

Adding a turbo will increase your engine’s power, but it won’t necessarily increase the car’s top speed by itself. That’s because the gearbox and final drive ratios in your car were carefully designed so that the engine is producing maximum power when the car is going at its top speed.

Why does turbo break?

Most failures are caused by the three ‘turbo killers’ of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil starvation.
