Do EcoBoost Engines Make Noise?

EcoBoost engines are hybrid devices that combine gasoline fuel with an electric motor.

This is to produce efficient power at lower engine speeds and provide greater performance in the higher engine speed range than traditional combustion engines.

Yes! EcoBoost engines make noise because the turbochargers replace the single factory turbocharger with two turbochargers and combine their power to create a supercharged air induction system. The supercharged air induction system whistles when the engine works, or you give it a throttle.

You can typically hear the sound just under the hood of your car, and you can often hear it at idle. In contrast, a single turbocharger produces a more mellow-sounding whine while driving.

If you have a turbo car and have never heard the noise, it may be time to buy new tires. It is probably okay to hear the whine at idle, occasionally at higher RPMs.

If you always hear the whine and it is obnoxious, it may be time to get new tires or ask your service advisor to look under the hood.

If the noise only occurs when you accelerate, it will likely be an issue with the factory turbocharger.

A single turbocharger will normally make a loud whistle at full throttle on the highway, but it will not make a loud noise at low to mid RPMs.

It’s important to understand that even if you change the factory turbochargers for aftermarket units, changing one part of the exhaust, like mufflers or pipes, does not usually affect how loud your engine sounds.

Sometimes, your aftermarket exhaust will make your whine louder or quieter.

Why Does My EcoBoost Rattle?

1. Worn or Loose Timing Chain

Timing chains are what synchronize the camshafts to rotate at a precise pace. If the timing chains are worn or loose, they can rattle due to slack in the chain.

2. Loose Rockers

If the rockers pushing down on valves become loose, they can knock against other engine parts and cause a rattling noise.

3. Loose Valve Cover

A loose valve cover can rattle due to its bolts becoming loose. Tighten the bolts and spray some belt dressing to prevent future rattling.

4. Faulty Fuel Jets

If the fuel jets are damaged or worn inside the cylinder head, they may rattle. To prevent this, replace the faulty jets with new ones.

5. Clogged Oil System

If there is a blockage in the oil system, then it can cause a rattling noise. If this is the case, place some oil in the system and see if that solves it.

6. Loose Radiator Fan

If the radiator fan is not attached or loose, it can make a rattling noise. Tighten the bolts to avoid further issues.

How Do I Know If My EcoBoost Is A Misfire?

A misfire occurs when the injector valve in an engine doesn’t close properly, allowing fuel to flow into the spark plug hole. This problem creates a lot of high-pressure fuel that will eventually shorten the life of your engine.

I have compiled a table of signs that your EcoBoost is misfiring and the signs you should take note of.

Rough IdlingVibrating, Shaking and Making a grinding noise.
Reduced PowerLonger to accelerate, Max speed is lower and Feels sluggish.
Engine Warning LightMore frequent shifts,Reduced fuel efficiency and Poor performance.
Engine KnockHarder to start (misfiring), Loss of power and misfiring while driving are common. 
Stumbling Exhaust NotePoor acceleration,Reduced power,Engine warning light illumination, Loud and rattling exhaust note.

Why is EcoBoost so powerful?

Ecoboost boasts so much power because of:

1. Turbocharging

EcoBoost engines have turbos that provide a large volume of air for combustion. When the exhaust gas pressure drops, the turbine blades move and send high-pressure air back into the engine. This is called “turbo lag.”

2. Variable Valve Timing

The valves in Ecoboost engines will close sooner than those in other engines, which helps produce more power from the same amount of fuel by closing off areas of lower compression before higher compression regions. 

3. Fast-Acting Electronic Fuel Injection

EcoBoost engines have fuel injection controlled by the computers in your car. It’s set up so that you inject fuel into the cylinder while it’s still compressing.

Because of this, there isn’t a delay after the intake valve closes before fuel is injected, and there is no interruption in fuel flow. 

4. Auto-Ignition

Computer chips and injections control the ignition timing and the fuel injection systems in Ecoboost engines. These systems help the engine perform well, even with a little fuel.

5. High-Octane Gasoline

Some new technology in making Ecoboost engines improves fuel efficiency and reduces emissions, especially when running on high-octane gasoline.

6. Intake Manifold

The intake manifold is the tube that connects the throttle and the cylinders where gasoline is ignited.

Ecoboost engines have a port between the engine and front-mounted intercooler that directs air from the supercharger into the manifold.

This allows the pulling of more air into the engine for better power, especially at high speeds.

Does EcoBoost Have Spark Plugs?

Yes, it does! You can find the spark plugs in EcoBoost everywhere on the side of an engine. They are part of a system that will help run an efficient engine with increased power output and improved fuel economy compared to other engines on the market.

The system consists of a coil pack that will help to produce a spark when required. You can locate the coil packs in the main computer within the engine.

Each cylinder has its spark plug corresponding to the number of spark plugs on the side of each cylinder.

Because Ford engineers are continually trying to make engines more efficient and improve fuel economy, they also put other options for harnessing power into their engines.

One option is using EcoBoost, which uses smaller engines and plugs for output power.

From my experience, these plugs need replacing simultaneously as an exhaust manifold is replaced.

Do EcoBoost Engines Make Noise?

If too many miles are put on your EcoBoost engine, it’s because the wires inside of the coils have frayed or corroded.

The mechanic will look at all of the coils and should tell you if one or more is bad. If that is the case, you will know the engine is running rough, or they could stumble on an engine problem when they look into the coils.

Does EcoBoost Increase Horsepower?

Yes! EcoBoost increases horsepower, torque output and also enhances fuel efficiency. It features a twin-scroll turbocharger that is more efficient and powerful than the turbocharged V6 found in other models.

The mountant-mounted six-speed transmission delivers fuel economy along with increased performance.

At the same time, the engine’s Direct Injection System uses low-pressure injectors to draw air into each cylinder rather than pistons to deliver a precise mixture of fuel and air.

The EcoBoost also features a new high-output electric motor mated with the port-driven turbine of the twin-scroll turbocharger. This drives air from the exhaust manifold into the intake side of the turbocharger.

The electric motor also improves torque output in low and mid-speed driving conditions. It uses about 20 percent less fuel and emits fewer greenhouse emissions.

The new technology delivers an average of 11 percent better fuel economy and a 4 percent improvement in power and torque over existing 2.0L EcoBoost engines.

The engine features a larger turbocharger, which provides more power per engine size. The 3.5L EcoBoost also offers increased fuel efficiency, lower emissions, and a broadened power band.

Does EcoBoost Mean Twin Turbo?

No! EcoBoost does not mean twin turbo. Although many EcoBoost engines use twin-turbocharging technology, the turbochargers are not twin-turbo units.

As such, EcoBoost is a Ford Motor Company marketing term that describes their line of turbocharged engines and not the type of turbocharger unit used.

EcoBoost turbos use wastegates to deliver more air to the cylinders by bypassing some of the exhaust gases, allowing a smaller turbocharger unit to provide the same boost as a similar-sized turbocharger unit operating at peak boost.

Wastegates then drive the larger turbochargers to give additional benefits for reduced overall engine response, improved throttle response, and enhanced power delivery throughout all RPM ranges

It ues exhaust pressure generated from the engine’s exhaust gas.

Pressure is related to the density of the gas or liquid, so bypassing some exhaust gases before entering the tube and turbine can generate greater pressure in the cylinder.

This is called a blow-off valve (BOV) or diverter, similar to the system used on turbocharged race cars.

The twin-turbo system routes some exhaust gases through a second turbine and into the primary (large) turbo.

The primary turbo controls the airflow for both turbines, and wastegate pressure is applied to the secondary (smaller) turbo.

The secondary turbo helps compensate for any lag in response to high boost conditions so that minimal lag is present when applying full throttle.

Can You Add A Turbo To An EcoBoost?

Yes! Modifying the engine and supporting system can add a turbo to an EcoBoost.

1. Start by removing the stock exhaust manifold.

2. With the bolts removed, you must remove the four bolts from one of the intake manifold’s corners/bends.

3. Use a large pipe wrench on two nuts and remove them from their moorings in the engine, then lower it down to drain oil into a pan below it.

Once this is complete, please take out your turbocharger and fit it into place onto the engine before starting up again.

4. You can now remove the bend holding the stock manifold in place and install the turbocharger.

5. Now you’re ready to reassemble everything in reverse order – oil pan first, then intake manifold with turbo in place, exhaust manifold next, and finally, the bolts for it all to tighten back into. It should be ready to go.
