While you’re on the open road, having a turbocharger installed on your engine can boost speed and power. However, sometimes a turbocharger can run into issues, preventing the intensity you desire. So what are the causes of low turbocharger boost pressure? Let’s take a look and find out.
How Do Turbochargers Work?
Turbochargers cause forced induction, compressing and pressuring it before reaching the engine. Because of the turbocharger, air pressure is higher inside the engine, resulting in more horsepower—the turbines spin, pumping air faster than a standard engine, producing more power and force.
Causes of Low Turbocharger Pressure
So what are some of the causes of low turbocharger boost pressure? It can result from many things, such as air leaks or oil starvation. Let’s look and see why your turbocharger isn’t producing the power it should.
Oil Starvation
Oil is essential to keep your engine in working order and operating optimally. However, when a turbocharger becomes starved of oil, it results in poorer performance on the road with long-term, irreversible damage. Oil starvation can come from a leak or a restriction between the turbo and the engine.
Air Leaks
Over time, hoses can become loose in your turbocharger. Consistent and robust air pressure is necessary to have optimal turbocharger performance. Check for any loose connections and hoses if you notice a substantial difference in how your turbocharger delivers power while you drive.
Unfree Turbines
Restricted exhausts can obstruct a turbo turbine connection, resulting in low boost pressure. Because the engine must produce a larger pushback, it decreases the amount of energy that must transmit from the cylinders for power while driving. Make sure there are no obstructions in your turbine so air can flow smoothly.
Spotting Low Turbo Boost Pressure
If you suspect that you aren’t achieving appropriate pressure for your turbocharger, there are a few ways to check for underperformance. One way to observe is through the vacuum gauge or boost indicator light, as it will show signs of needing repair.
Another way is checking the wastegate operation, checking for immobility or the inability to close fully. Lastly, you can inspect the turbocharger itself, such as checking for wobbly shafts, cracks, fissures, chips, and erosion.
