Is turbo lag good?

Turbo lag is an inherent failing of the turbocharger design. Car makers have done their best to reduce turbo lag from the factory, however a car’s turbo lag can increase over time.

Does turbocharger have turbo lag?

Compared to naturally aspirated engine, turbocharged engines tend to give out cleaner emissions. And when the turbocharger does kick in, the driver feels a sudden surge in power. However, there is a short time that is spent between pressing of the accelerator and the surge coming in, this time is called turbo lag.

What happens during turbo lag?

Turbo lag is the hesitation or slowed throttle response you experience when driving a turbocharged vehicle, before the turbocharger starts to kick in and provide extra power to your engine. Once a turbo reaches the required speed (known as spooling up) it can then begin to and force more air and fuel into the engine.

Do all turbos lag?

It’s the delay between when you open the throttle and when the turbo begins delivering boost—when the engine is above its boost threshold RPM. Some engines have nearly zero turbo lag, some have a ton. But there isn’t an engine out there that can deliver an immediate hit of boost below its boost threshold RPM.

Is idling bad for turbos?

Drive your car gently for the last minute or two of the drive, or let the car idle afterwards for at least 60 seconds. By letting it run. the oil will continue to circulate and cool down the turbo. Excessive boost pressure can cause heavy, damaging surge or overspin the turbocharger at the top end of the RPM band.

Do turbos make boost at idle?

Boost pressure is usually very low at idle no load condition. Turbo is turning at lower speed due to smaller volume of exhaust going thru turbo. Your highest boost will happen at full load on engine and has the most volume going thru the turbo . A lot of engines now use a exhaust bypass to limit max boost pressure.

What is the actual meaning of “turbo lag”?

Turbo lag is simply the amount of time required for the turbo to spool up and hit max boost. During a race, when both cars hit the gas at the same time, the one with a turbo will require a second or more until their engine produces maximum power from the turbo boost.

What are the causes of turbo lag?

Causes of slow turbo spool/turbo lag Boost Leak / Exhaust leak. A boost or exhaust leak is the most common problem when it comes to turbo lag. Faulty Wastegate. Bad Turbo Boost Pressure Solenoid Valve. Turbo boost pressure sensor. Broken turbocharger or supercharger. Faulty camshaft timing. Wrong turbo for the engine. Incorrect ignition timing. Lean air-fuel mixture.

How to eliminate turbo lag?

1) Add Nitrous Oxide. If you’re looking for a way to reduce turbo lag that’s akin to magic, look no further than nitrous oxide. 2) Increase Compression Ratio. In the 1980s, it was common to see turbocharged engines using compression ratios in the 8:1 range to compensate for the heat and pressure as boost 3) Add A Wastegate. A turbo can be tuned with a smaller exhaust housing that will spool the turbo quicker, and an exhaust wastegate can then be added to bleed 4) Narrowing the Powerband. Turbochargers are best at supplementing an engine that’s at a constant airflow state, so having a narrow powerband is useful in reducing turbo lag. 5) Sequential Turbocharging. Sequential turbocharging works by pairing a small turbo making power from, say, 2,000 to 4,000 rpm, and a second turbo that takes over from 4,000 to 6,000

Is it really turbo lag?

Turbo lag is the jargon used to describe the slight lag in reaction time from when you press the accelerator pedal to the car actually surging ahead. This lag usually comes in diesel cars that have large turbochargers to develop more torque, but this peak torque only comes in when the engine revolutions per minute (RPM) is around 2000 rpm or so.
