Turbocharged engines are known for their better speed and performance. However, they can still develop some problems as you use it. One common problem is turbo lag, and when this happens, it can get frustrating for a driver who is used to a certain level of performance from their BMW model.
While the turbocharger’s function is to provide better rides and more boost for your BMW’s engine, a lag could compromise the engine’s function. This guide will provide enough information to help you deal with turbo lag in your BMW.
Understanding Turbo Lagging in Your BMW
Before we move on to dealing with turbo lagging in your model, you should first understand what it means and why it happens. The turbocharger is a device that helps to improve an engine’s performance by forcing more air into the engine, enhancing combustion, and boosting the engine’s functions.
However, unlike naturally charged engines, turbocharged ones do not immediately produce power when a driver hits the throttle pad, it takes a bit of time before this happens. The delay between when you hit the throttle pad in your BMW and when its engine responds with a burst is called a turbo lag.
A turbo lag typically happens when there aren’t enough exhaust gasses to reel the engine into action and for the few seconds that it occurs, the engine remains sluggish. The turbo has turbines that spin, based on pressure from your engine’s exhaust gasses, which then generate the boost that spurs the engine to action. If your engine does not generate enough exhaust gasses for this pressure, there will be a lag.
The most noticeable period for a turbo lag is when you are driving on a low RPM, which does not generate enough exhaust gasses for engine action.
How to Handle a Turbo Lag in Your BMW
While a turbo lag is not always a big problem, it could affect the quality of your rides or put you at a disadvantage during a race. Here are some tips to help you deal with the problem:
- Upgrade Your Turbocharger: One of the ways you can solve turbo lag issues in your BMW is to install a larger turbocharger with better performance, and consequently, less lag problems. There are various upgrade options available and you should consult with your mechanic on the best way to go about this.
- Install Upgraded Wastegate: Adding a wastegate to your car’s turbo can also help you deal with turbo lag. The wastegate provides better control of exhaust gasses to control the pressure in the turbo and also engine boost. With a better wastegate, your car’s turbo can control boost pressure better, and also reduce the risk of turbo lag.
- Make Driving Adjustments: Adjusting your driving method can also help you overcome turbo lag issues in your car. Ensure that you keep your RPM (rev per minute) up for more exhaust gas productions which will then fuel the engine boost and prevent a lag. You should also ensure that you hit the throttle with a gradual increase rather than all at once as slow acceleration helps your engine build up boost slowly for better engine performance.
- Upgrade Exhaust System: Another upgrade you can make to handle turbo lagging in your car is an exhaust system upgrade. This involves installing a high-flow downpipe, replacing the exhaust manifold, or installing a performance catalytic converter. Doing this will help to improve airflow, emission control, and exhaust gas pressure all to supply sufficient engine boost for better performance and reduced lagging.
- Improve System Maintenance: Maintenance is another way in which you can improve your BMW’s turbocharger as poor maintenance can contribute to lagging. Key maintenance actions such as regular inspections and checks, air filter replacements, and oil checks and changes can be instrumental in getting rid of turbo lag.
