Why do turbo engines not rev high?

It is simply much more expensive to make high reving Turbo petrols. Need much better balanced rotating components, lighter & stronger internals. NA engines

NA engines

Owing to innate restriction in the engine's inlet tract, which includes the intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric efficiency of less than 100 percent—and a less than complete air charge in the cylinder.

Naturally aspirated engine - Wikipedia

may rev to much higher rpms but they aren't making much torque at those RPMs, high horsepower is simply coming from more revs( hence more bangs per minute).

Do turbos lower rpm?

Turbocharged engines make big torque at low rpm, but those two numbers, peak torque and its corresponding rpm, don't tell the full story, as boost pressure isn't solely a function of engine speed.

Do turbos increase rpm?

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. The turbine in the turbocharger spins at speeds of up to 150,000 rotations per minute (rpm) -- that's about 30 times faster than most car engines can go.

At what rpm do turbos kick in?

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.

What is the disadvantage of turbo engine?

Disadvantages of a Turbo Engine

Well, more power means more energy output per second. This means that you have to put more energy when you use it. So you must burn more fuel. In theory, that means an engine with a turbocharger is no more fuel efficient than one without.

How Do Some Engines Rev To 9,000 RPM?

Do turbos shorten engine life?

Turbochargers, Supercharges, and Nitrous all create higher cylinder pressures. This DOES reduce engine life ... PERIOD. Turbos and Superchargers make more heat, and heat reduces an engine's life ...

How long will a turbo engine last?

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.

Do turbos always spin?

It will always spin while exhaust gas is flowing (which it always will be if the engine is running). However, it wont be spinning very quickly at low throttle openings (regardless of engine RPM) so the pressure in the in-take manifold wont be very high.

Why use a supercharger over a turbo?

Supercharging Pros: Produces significantly more horsepower than turbocharging. A quick solution to boosting power in larger displacement engines with more cylinders. No power lag as is seen with turbocharging; power delivery is instantaneous.

Does turbo save fuel?

Are turbocharged engines more fuel-efficient than naturally aspirated engines? In theory, turbochargers can boost the efficiency of an internal combustion engine by anywhere from 10 to 30 percent.

How much HP can turbo add?

However, how much horsepower does a turbo add? A turbo can increase an engine's horsepower by 30 to 40 percent or about 70 to 150 HP. In the case of a supercharger with a direct connection to the engine, that can be from 50 to 100 percent.

What causes turbo lag?

Turbo lag is affected by a number of different factors, including turbo size relative to engine size, the state of tuning of the engine, the inertia of the turbo's rotating group, turbine efficiency, intake plumbing losses, and exhaust backpressure.

Is a twin-turbo better than a single?

Twin-scroll turbochargers offer higher levels of gas-flow efficiency, reduced turbo-lag and allow engines to be tuned for slightly more power than the single-scroll variety. Even the BMW inline-6s no longer need a pair of turbos, relying instead on a single twin-scroll system.

Does turbo increase acceleration?

Turbochargers are cheaper than superchargers, more efficient, and less impactful on your engine. One of their downfalls though, is their lack of efficiency and power boost at low RPMs. They definitely increase your top speed and acceleration, but not until a certain level of speed.

Can a car be twin turbo and supercharged?

Yes, using a turbocharger in tandem with a supercharger is very much possible. In fact, racing cars have been using twin-charging (turbocharger+supercharger) to increase the power both at the low RPM band and the high RPM band.

Why do superchargers whine?

Superchargers are driven by a belt connected to the engine crankshaft. This means that they spin at a high rate of speed, which can create a whining noise. Another reason for the characteristic supercharger whine is because of the way air moves through them.

Is Twin Turbo better than supercharger?

Probably not, but given their nature, you can draw the conclusion that a supercharger is going to be more useful on the street and when racing from a dig thanks to its instant power, whereas a twin-turbo setup will likely give you more power, but it tends to take just that tiny bit longer to deliver it.

Do turbos work better in cold weather?

As air temperature increases the density of the air, and the amount of oxygen it holds, decreases. This means that the turbocharger has to work harder, spin faster and compress more air to produce the same amount of boost it would at lower temperatures.

Does turbo work on idle?

Idling the engine cools the turbo because it circulates the oil, yet does not make the turbo "work." The amount of cooling it needs is directly related to the way you just finished driving it. When you drive it gently around town, 15 seconds should be more than adequate.

What should you not do with a turbo engine?

Do turbo engines require more maintenance?

It depends on the type of maintenance. 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.

Do turbocharged engines need premium gas?

Not all turbocharged cars need premium gas, but it's a more common requirement among turbos than other kinds of engines, thanks to the way these engines work. The name turbo comes from the turbine these engines use to inject more air into the air-fuel mixture in the combustion chamber.

How do you maintain a turbo engine?
