¿Los turbos provocan lag?
Turbo lag is caused by low engine speeds. Basically, when the car is coasting or power is not being applied, there are not enough exhaust gases to spool the turbine/s.
How do you get rid of turbo lag?

What causes excessive 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.
How long should turbo lag be?
about 1 second
In short, turbo lag is the delay between pressing the accelerator and feeling the turbo kick in. This usually takes about 1 second in newer cars.
Which turbo has less lag?
Twin-scroll turbos
A twin-scroll turbo effectively brings together twin-turbocharging into one neat package. Using two inlets for the exhaust gases instead of the conventional single inlet, this form of turbo is designed to operate at small and high exhaust gas flow rates, reducing the effects of turbo lag.

What RPM does a turbo 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.
Does anti lag destroy turbos?
Anti lag is actually quite brutal. All of that backfiring can cause extra wear and damage to the rally car engine and turbo.
What are the signs of a turbo failing?
The symptoms of a damaged or failing turbo are:
- Loss of power.
- Slower, louder acceleration.
- Difficulty maintaining high speeds.
- Blue/grey smoke coming from the exhaust.
- Engine dashboard light is showing.
At what RPM is turbo activated?
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 usually spins at speeds between 80,000 and 200,000 rotations per minute (rpm) — that's up to 30 times faster than most car engines can go.
Do turbos need time to break in?
Allow the vehicle to idle for 10-15 minutes without applying any throttle. Even at idle, the turbo can be spinning at as much as 28,000 RPM's on certain models. Use this time to check for any loose fittings, hoses, exhaust leaks, and to bleed the cooling system of any trapped air. 7.
How long does it take for turbo lag to spool?
Turbo lag is what you feel when you're waiting for the boost to kick in. Because the turbines do take time to spool (or spin), there is some degree of turbo lag. After depressing the accelerator pedal, it takes about a second (in most modern cars) for the turbo to spool.
Does bigger turbo mean more lag?
Carmakers use several solutions to deal with turbo lag. These include utilising twin-scroll turbos or using two smaller turbos instead of one large one to boost an engine. Smaller turbos spool up much faster than a single large turbocharger.
At what RPM do turbos kick in?
A decent turbo hits full boost at 3k rpm, but it varies depending on the mechanical efficiency of the turbo and how much exhaust is being put out.
Should you rev a turbo?
Cold engine revving
A cold engine is highly susceptible to wear and tear. It does not matter if the engine is naturally aspirated or turbocharged, a cold engine should not be revved hard. In turbocharged engines, the damage can be much more. The engine oil lubricates the engine and keeps it safe from any wear and tear.
Does turbo work at low revs?
As well as increasing power, turbos increase torque – an engine's strength – particularly at low revs. That's useful in small petrol engines which tend to produce not much torque at high revs without a turbo.
Does idling hurt turbos?
While there are a lot of valid arguments supporting the cause of idling, even the naysayers will agree you've got nothing to lose by practicing the idling rule. Abusing your turbocharger can affect its longevity. With time, the turbo will become less effective.
What is the downside of anti-lag?
Cons of anti lag
The sheer pressure caused by anti lag will test your exhaust joints and show any weak spots. Lower engine and turbo life and worse reliability**. You will kill any catalyst fitted (hence why ALS is not suitable for road cars.)
What is the most common turbo failure?
oil starvation
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.
What does an unhealthy turbo sound like?
Loud noises: If your vehicle has a bad turbo, you may hear loud noises that sound like whining or screeching. So if your vehicle is running and you hear a loud whining sound that increases in volume as the problem goes unfixed, this is most likely to do a turbo problem.
Is idling a turbo bad?
While there are a lot of valid arguments supporting the cause of idling, even the naysayers will agree you've got nothing to lose by practicing the idling rule. Abusing your turbocharger can affect its longevity. With time, the turbo will become less effective.
Why should you let a turbo 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.
Is idling bad for turbo engines?
While there are a lot of valid arguments supporting the cause of idling, even the naysayers will agree you've got nothing to lose by practicing the idling rule. Abusing your turbocharger can affect its longevity. With time, the turbo will become less effective.

Does a downpipe reduce turbo lag?
It decreases turbo lag and generates more spool. When you make this switch, you're reducing intake charge and engine temperature. This will bring the increase in engine power you were craving.
Can you over spool a turbo?
If the turbo continues to over speed, it can over boost the engine, resulting in serious damage to the internal components and potentially complete engine failure !
What is turbo lag disadvantages?
Any car whose engine is experiencing a turbo lag will have difficulty maintaining high speeds and would not accelerate smoothly. Engine Wears Out At a Faster Rate: The faster you drive, the more stress you put on the engine.
