What Is The 6.7 Powerstroke Turbo?

how to make a 6.7 powerstroke turbo louder

Powerstroke is the name used for several diesel engines for trucks that Ford Motor Company produces.

It is widely applied from the Ford F-Series to the E-Series, Ford LCF, and Ford Excursion.

Since 1994, the Powerstroke family has existed under the manner of re-branding engines manufactured and mass-produced by the Navistar International Corporation.

From this time, they are mostly added to Navistar’s line of medium-duty trucks.

The 6.7 Powerstroke turbo, or 6.7L Powerstroke V8, was first released to the public since the year of 2011. Ford has designed, manufactured, and produced its own diesel parts.

During this time, the 6.7 Powerstroke turbo must compete against large-block gasoline engines on the market, such as V8 and V10.

How To Make A 6.7 Powerstroke Turbo Louder?

To make the 6.7 powerstroke turbo louder, shut down your car’s engines and open the hood to get access to the snap rings. Removing all these rings will make the engine noisier.

Below are the detailed steps on how to get more turbo whistle 6.7 Powerstroke?

  • Step 1: Park your car slowly by disengaging the brake and wait for its engines to release heat before knuckling to the procedure. If your vehicle shuts off when brakes are pressed, there might be something wrong.
  • Step 2: Lift the hood and pinpoint the manifold cover’s location. Once you have determined it, try to release the nuts and bolts holding it in place.
  • Step 3: Turn your attention to the intake hose. You must not remove the intake but something inside it, namely the snap ring. It is usually located in the intake’s mouth, so use a screwdriver to take it out.
  • Step 4: Once you have pried the snap ring off, you will notice a silencer ring forming an entire cycle. Cling to a screwdriver again to pop the ring out of an intake.
  • Step 5: After removing all the rings, replace your manifold cover with a new one. Install the above devices in their original positions before reactivating the 6.7 Powerstroke turbo. Good luck!

What Are Other Alternatives You Can Make A Powerstroke Turbo Louder?

Suppose you find the process too difficult; here are some alternative methods worth your consideration. Keep scrolling down for further information!

Use An Aftermarket Downpipe

An aftermarket downpipe can amplify the sound emanating from a Powerstroke turbo by facilitating the travel of sound waves and preventing unnecessary collisions.

There are two types of downpipes on the market: a catless downpipe and catted one. Their main differences lie in a catalytic converter.

A Catted downpipe is equipped with this device, but a catless product doesn’t have one.

Their prices are reasonable, at about 200 dollars, and the installation of aftermarket downpipes is not very tricky, only lasting 2 hours.

Use An Open Box Intake System

The open-box intake system proves its effectiveness by enhancing the 6.7 Powerstroke turbo’s noise due to a lack of an airbox.

In this way, it can make you hear additional turbo noise.

If you don’t know how to differentiate it from other airbox-equipped products, look for an intake system resembling a mushroom head.

According to my experience, after buying and installing this device on my car, I feel pleased with the sound improvement.

The noise is still loud, and I don’t need to involve much elbow grease.

Remove The Engine Cover

The engine cover is functional at suppressing the noise, not for decorative purposes.

This is attributed to the better airflow over your motor parts, so the sound seems to be amplified more.

However, the cover also helps prevent the excess heat from letting out from your automobile’s engines.

The loss of too much heat is able to hinder the operation of overall mechanics, particularly turbo. This problem can be exacerbated in the winter.

Use A Cold Air Intake

Some modern cars are not equipped with a cold air intake, which seems like an optional part. Yet, if you want to raise the sound level of your Powerstroke turbo, this device might come in handy.

After installing it, you can hear a distinct change in your turbo’s sound, and it is clearer when you engage the accelerator or rev up your vehicle.

However, if you notice the car doesn’t go past 40 MPH when accelerating, it is a bad sign for repair-needing components.

The cost for a cold air intake ranges from 300 to 350 dollars, which is reasonable on the market.

Given the installation, the method is straightforward, with a plier, a screwdriver, and a ratchet set.

Tune For Higher Boost Pressure

If you don’t know what the boost pressure is, this term refers to extra air being forced into the engine.

Elevating the boost pressure helps facilitate more airflow inside your vehicle, causing the stock turbo to spin harder and generating more noise.

However, when implementing this approach, you should pay close attention to air contamination. A typical turbo has a wastegate that directly emits exhaust fumes into the atmosphere.

Use A Turbo Exhaust Whistle

The eventual approach to amplifying the turbo’s noise is attaching an exhaust whistle to the exhaust pipe. Under this circumstance, you will hear greater sounds when speeding up.

A turbo whistle is safe for your automobile because it is often made of lightweight and stainless aluminum, and the process of attaching it doesn’t waste much effort.

If you encounter difficulty during the procedure, call a professional mechanic for help.

How Do I Make My 6.7 Powerstroke Turbo Diesel Spool Louder?

The most common formula for boosting your 6.7 Powerstroke turbo spooling sound is dumping the aftermarket exhaust either under the driver’s door or behind an engine’s exhaust housing.

In this case, the impeller would not be silenced by an exhaust system, triggering a loud whistle.

Another way is changing its compressor wheel to a high-flow wheel with the purpose of enhancing the induction as well as spooling sound.

When the replacement occurs, the aftermarket turbo could allow more air to flow into it, given the same boost pressure.

Why Does A Turbo Diesel Cause More Noises Than A Turbo Petrol?

Despite a smaller turbocharger, a turbo diesel could generate louder noises than a turbo petrol. This is mainly boiled down to a larger displacement of a turbo-diesel engine.

With a greater displacement, the compression ratio increases, heightening the productivity of a combustion process and resulting in higher speed brought by a compressor housing wheel, measured by RPM units.

All contribute to a turbo diesel’s deeper and louder spooling sounds than its petrol counterpart.

Will My 6.7 Powerstroke Turbo Trigger Louder Sounds With An External Wastegate?

The answer is no.

An external wastegate is responsible for releasing the extra boost pressure onto the atmosphere, so the flow of exhaust fumes doesn’t need to move through an exhaust system.

As mentioned earlier, you will notice the environmental problem induced by this device.

Returning to the question, it doesn’t make your turbo louder because it emits the fumes before the turbocharger’s operation via small gates that open when the boost pressure reaches a threshold.

Frequently Asked Questions

Will A Larger Exhaust Make My Turbo Sound Louder?

Not really.

The sound emanating from your car’s Powerstroke turbo depends on numerous factors, such as the surrounding environment, the operation of that turbo, or its working with other related motor parts.

Sometimes, a modern exhaust model with a bigger size cannot be paired with your turbocharger.

In this case, you might easily notice a change in the spool noise right from the start-up, and the noises could be reduced if everything turns worse.

That’s why you must carefully search for information about the exhaust or any engines that you are going to buy. Consulting advice from a reliable mechanic is also a helpful way.

What Are Some Diesel Turbo’s Noise Problems?

Following are common issues with the diesel turbo’s sound that you should pay close attention to.

  • Rattling is one of the most popular problems, becoming more distinct when you accelerate your automobile. It is caused by the incorrect ratio of a mixture between fuel and air.
  • Ticking noise is another worry rendered by reciprocating components, including pistons, valves, and pushrods.
  • The meshing sound pops up when your Powerstroke turbo does not rotate well or gets blocked by strange objects.
