EcoBoost Noise When Accelerating

If you own a Ford vehicle with an EcoBoost engine, you may have noticed a peculiar noise when accelerating. The EcoBoost noise is often described as a whistling or chirping sound, and it can be concerning for drivers who are not familiar with this type of engine. In this article, we will explore the reasons behind EcoBoost noise when accelerating and what you can do to minimize it.

What is EcoBoost?

Before we delve into EcoBoost noise, it’s essential to understand what EcoBoost is. EcoBoost is Ford’s trademarked name for its line of turbocharged, direct-injection gasoline engines. These engines are designed to deliver a balance of power and fuel efficiency, and they use a combination of turbocharging and direct fuel injection to achieve this goal.

Why Does EcoBoost Make Noise When Accelerating?

EcoBoost noise is primarily caused by the turbocharger, which is a critical component of the engine. The turbocharger works by compressing the air that enters the engine, which increases the amount of oxygen available for combustion. This process creates more power, but it also produces more noise.

Additionally, EcoBoost engines use a unique design called the Integrated Exhaust Manifold, which places the exhaust ports inside the engine’s cylinder head. This design improves fuel efficiency, but it also creates more noise as the exhaust gases are forced through smaller passages.

How to Minimize EcoBoost Noise When Accelerating

While EcoBoost noise is a natural characteristic of these engines, there are a few things you can do to minimize it:

  1. Use high-quality fuel: Using high-quality fuel with a high octane rating can help reduce EcoBoost noise by providing a cleaner burn and reducing engine knock.
  2. Maintain your vehicle: Regular maintenance, including oil changes, air filter replacements, and spark plug replacements, can help ensure your engine runs smoothly and quietly.
  3. Upgrade your exhaust system: Upgrading your exhaust system to a high-performance model can help reduce EcoBoost noise while also improving your vehicle’s performance.
  4. Install a turbocharger silencer: Installing a turbocharger silencer can help reduce the noise produced by the turbocharger, making your engine quieter.

Why is there a noise coming from my engine when I accelerate?

There could be several reasons why there is a noise coming from your engine when you accelerate. It could be due to a problem with the exhaust system, engine belts, bearings, or even the transmission. It’s best to have a professional mechanic diagnose and fix the issue to prevent any further damage to your engine.

What causes Ecoboost rattle?

EcoBoost rattle is typically caused by issues with the timing chain or the timing chain tensioner. Over time, these components can wear out, causing a rattling noise when the engine is running. It’s important to have the issue diagnosed and repaired by a professional mechanic to prevent any further damage to the engine.

How do I know if my Ecoboost turbo is bad?

If your EcoBoost turbo is bad, you may experience symptoms such as loss of power, decreased fuel efficiency, blue or black smoke from the exhaust, a whining noise from the turbocharger, or a check engine light. It’s important to have your vehicle diagnosed by a professional mechanic to determine if the turbo is the cause of these symptoms and to have it repaired or replaced if necessary.


EcoBoost noise when accelerating is a common characteristic of Ford’s turbocharged engines. While it may be concerning for some drivers, it’s essential to remember that it’s a natural byproduct of the engine’s design. By following the tips outlined in this article, you can minimize EcoBoost noise and enjoy the performance and fuel efficiency benefits of your EcoBoost engine.
