It is a universal fact that no machine can deliver 100% efficiency and turbochargers are no different. Turbochargers boost the car\u2019s performance by generating more power through the engine\u2019s exhaust. <\/p>\n\n\n\n

If you drive a turbocharged car, you might have experienced a lag before the turbochargers start and make a full boost. To tackle this issue, automakers have come up with different strategies to reduce turbo lag. Let\u2019s find out the causes of turbo lag and how to reduce it in detail.<\/p>\n\n\n\n

What is Turbo Lag?<\/h2>\n\n\n\n
\"what
Turbo lag is the delay you experience before a turbocharged engine’s burst of torque<\/figcaption><\/figure>\n\n\n\n

To understand what turbo lag is, you must know how a car turbocharger<\/a> works. Turbochargers are based on the phenomenon of forced induction systems. To put it simply, it compresses the air entering the car\u2019s engine. The compressed air allows a more rich air-fuel mixture. However, a rich air-fuel mixture increases the engine’s power.<\/p>\n\n\n\n

Turbo lag is the delay that occurs between accelerating the car and experiencing a turbocharged engine’s burst of torque<\/a>. The lag is the lengthiest when the engine is in a low-rpm, low-load cruising mode. <\/p>\n\n\n\n

You will feel the turbo lag once you press the accelerator pedal in a turbocharged car, and notice a significant pause before the car starts to accelerate swiftly. The acceleration will increase noticeably when the turbo engages.<\/p>\n\n\n\n

Causes of Turbo Lag<\/h2>\n\n\n\n
\"causes
A turbo lag is caused by the time an engine takes to generate exhaust pressure to spool the turbo<\/figcaption><\/figure>\n\n\n\n

A turbo lag results from the time an engine takes to generate enough exhaust pressure to spin the turbine inside the turbocharger. And, consequently, pump compressed intake air into the engine. <\/p>\n\n\n\n

A turbocharger does not make a full boost right from the engine idling. Rather, a turbo requires a specific rpm range to drive additional air and fuel into the engine, also known as spooling up.<\/p>\n\n\n\n

How to Reduce Turbo Lag<\/h2>\n\n\n\n

Although numerous methods can assist, there is no one fix for turbo lag. Building a combination with the proper converter, compression ratio, cam, displacement, gearing, and brake system is helpful for the employed turbo.<\/p>\n\n\n\n

1. Add Nitrous Oxide<\/h3>\n\n\n\n
\"nitrous
Using NOS – Nitrous oxide is one of the ways to reduce turbo lag<\/figcaption><\/figure>\n\n\n\n

Nitrous oxide<\/a> is the solution if you’re searching for an immediate approach to reducing turbo lag. This gas causes cylinder pressures to soar, and that same energy is subsequently directed out of the exhaust system<\/a>, quickly spinning up the turbine. <\/p>\n\n\n\n

Nitrous systems can reduce spooling times greatly when used properly. But you should be aware that if your air-fuel ratio isn’t adjusted, for the increased oxygen during spooling, a significant backfire and engine damage could occur.<\/p>\n\n\n\n

2. Increase Compression Ratio<\/h3>\n\n\n\n

In the early days, it was common to see turbocharged engines using an engine compression ratio<\/a> of 8:1. This range compensated for the pressure and heat as the boost increased. That said, the car was operated on a low-compression, over-cammed engine that produced little power until the required boost was hit. <\/p>\n\n\n\n

Whereas, now it is common to find turbo engines with compression ratios between 9:1 and 10:1. This is due to advances in fuel and intercooling systems. These extra compression points significantly help turbos to spool. <\/p>\n\n\n\n

3. Add a Wastegate<\/h3>\n\n\n\n

To reduce the turbo lag, you can add a smaller exhaust housing to modify the turbo. This will cause the turbo to spool up more quickly. Additionally, you can use an exhaust wastegate to bleed off excess exhaust pressure generated at high engine speeds.<\/p>\n\n\n\n

In many conditions, a single turbo frame has at least three or four different exhaust housings. Therefore, adjusting an exhaust wastegate and a smaller exhaust housing is relatively simple to do.<\/p>\n\n\n\n

4. Narrowing the Powerband<\/h3>\n\n\n\n

To reduce the turbo lag you can get a narrow powerband. This is because turbochargers work best when an engine is operating at constant airflow. <\/p>\n\n\n\n

Multi-speed transmissions and larger-displacement engines (for a given power level) can noticeably reduce turbo lag. Doing so will allow the turbocharger to operate close to its maximum power-producing range.<\/p>\n\n\n\n

5. Sequential Turbocharging<\/h3>\n\n\n\n

Sequential turbocharging create an engine with a broad operating powerband. This is done by combining a small turbo that operates from, say, 2,000 to 4,000 rpm and then, a second turbo that operates from 4,000 to 6,000 rpm.<\/p>\n\n\n\n

Unfortunately, these technologies are complicated and expensive and are not employed in gasoline vehicles that often. However, petrol cars have been using sequential turbocharging frequently for many years.<\/p>\n\n\n\n

This is all about turbo lag and how to reduce it. Undoubtedly, turbo lag is an inevitable compromise you have to make when opting for a car with a turbocharged engine. However, with the current surge in technology, automakers have introduced strategies to resolve the issue.<\/p>\n\n\n\n
