What Turbo Lag Is and How to Get Rid of It

What Turbo Lag Is and How to Get Rid of It

By design, turbochargers increase engine power. Through the turbine-powered forced air induction, cool air compresses in the combustion chamber, where it compresses into warm air and releases out the exhaust. The compressed air pushes the cylinders to burn more fuel per second. With that process come many issues, however. One such issue every turbo owner must know is turbo lag. Fortunately, this guide on what turbo lag is and how to get rid of it will help.

What Is Turbo Lag?

Turbo lag is the issue within turbochargers between the throttle and torque power. It happens when an excessive amount of exhaust pressure builds up in the engine and slows the response of the turbo and pump compressor. Alternatively, you may experience turbo lag if minimal exhaust gasses spool the turbine. The intake air in the engine then only runs with a low-revolutions-per-minute and low-load situation. If you accelerate, there will be a lag with the turbo response. Diesel engines are more susceptible to turbo lags, given the reliance on compression ignition instead of spark plugs.

How to Fix It

Given the issues with turbo lag, it’s important that owners with turbochargers understand the proper troubleshooting procedures. There are several ways for reducing turbo lag in your vehicle. The first is adding nitrous oxide. Nitrous systems force energy out of the exhaust and decrease spool times. The second tip is to increase the compression ratio. Compression ratios between 9:1 and 10:1 offer greater compression against spooling than low-compression engines. You can also replace your entire exhaust system for greater energy emittance. While this might seem tedious, replacing the pipeline, manifold, oxygen housing, and downpipe may eliminate issues with your old exhaust system. It can also increase your horsepower and torque.

It’s possible that you may even need to replace your turbocharger altogether. Fortunately, we at TurboTurbos carry the highest quality refurbished turbos for sale at a reasonable cost.
