The fuel pump is arguably one of the most important components in a turbocharged car regarding performance, since it supplies all required fuel pressure for optimal combustion. A consistent fuel supply is also something that the turbocharged engines need as they pile on more boost than naturally aspirated engines tend to do. For example, fuel injectors in a turbocharged engine require pressure of 40-60 psi, as compared to the standard pressure level of 30-45 psi. This increased demand further emphasizes the need for a strong and efficient fuel pump.
The impact of a poorly performing fuel pump can be catastrophic A weak flow of fuel through the system can cause lean conditions, which mean too much air and not enough fuel is delivered to the cylinder_commit. If not corrected, this imbalance can lead to performance compromises such as turbo lag (i.e. the time needed for the turbocharger to spool up and provide power). Leaner mixtures can represent a power output reduction up to 25%, as indicated by the results of research conducted by the Automotive Research Center, and this is critical in regards to driving performance and acceleration.
Precise fuel delivery is critical for turbocharged engines due to the high risk of knocking causing catastrophic engine failure. Engine tuning specialist Lisa Hartman said, "It is important to assure a functioning fuel pump that meters out the correct amount of fuel for an engine to prevent pre-ignition and expensive damage." It becomes imperative that the fuel pressure always stays at its maximum, because any time it drops even for a short period then it will trigger knock sensors which will retard ignition timing and reduce power & efficiency.
The performance life of a turbocharged engine is directly proportional to the fuel pump it gets. Under ideal circumstances, a fuel pump must perform at least 100,000 to 150,000 miles or more depending on the quality of the fuel flowing through it and if has experienced operational stress. High temps and pressures done in turbo engines are a significant fiend for fuel pumps due to this kind of conditions added to increased bane, it is vital to keep tabs on those occurrence times of examination so as pumps operate well.
If a vehicle that is equipped with a turbocharged engine has lost power or is accelerating inconsistently and you suspect the reason for this may be a faulty fuel pump you can do one of the following checks. Symptoms of a failing Pump include hard start separates message delivery, use closure (fuel economy as much as 20%, If the pump does not align with fuel that engine) and / or bucking or surging on acceleration.
If you are curious about a fuel pump's role, then that is what it does to help your turbocharged engines in general. It helps optimize power output, prevents knocking (timing irregularity sensed in the form of a heavy sleeve tremor), and ensures long term engine health. A Fuel Pump with the correct output can, perhaps most importantly, improve the reliability and efficiency of a turbocharged engine especially for high performance applications. In high-performance-tuned vehicles, having a good-fuel pump can feel like your car is just that little bit more alive — especially when you floor it.
