Finding the right 6. 7 powerstroke turbos for your truck depends heavily on whether you're just trying to get back again on the road or if you're looking to convert your Ford right into a mountain-climbing beast. Considering that Ford introduced the particular 6. 7L Scorpion engine back within 2011, the turbocharger has gone through many iterations, and honestly, some were definitely better than others. In the event that you own a single of these vehicles, you probably already understand that the turbo will be the heart associated with the engine's overall performance, but it's furthermore one of the particular parts that can cause probably the most aggravation when things move sideways.
The particular Evolution of the six. 7 Turbo Design
When Ford first dropped the particular 6. 7, they will tried something quite radical with the 6. seven powerstroke turbos . From 2011 to 2014, they utilized what's called the Single Sequential Turbo (SST). It was a dual-compressor wheel design meant to give you the quick spool-up associated with a small turbo with the top-end power of the big one. On paper, it was amazing. In reality? It had some issues.
The primary problem with all those early Garrett GT32 units was the particular ceramic bearings. They were prone to failing, especially if you were pressing the truck tough or running higher boost levels. Whenever those bearings let go, it wasn't a "fix it following week" kind of situation; it had been an "I'm stuck on the part from the highway" situation.
In 2015, Ford realized they needed something more robust, so they changed to the GT37. This was the more traditional, bigger single-vane turbo that utilized steel bearings. It was a massive improvement in terms of dependability. If you're generating a 2011-2014 design as well as your turbo bites the dust, most mechanics will suggest doing a "2015 conversion. " This basically swaps out the particular old, temperamental SST setup for your very much more reliable 2015+ style. It's a bit of an investment, yet it saves the lot of headaches later on.
Typical Signs Your Turbo is Giving Upward
It's rarely a surprise when six. 7 powerstroke turbos begin to fail, as these people usually give you some indicators. The most famous you are the "dentist drill" sound. If you hear a high-pitched whining coming from under the cover that gets louder as you accelerate, your bearings are usually likely on their way out.
Another big red light is blue or gray smoke from the tailpipe. This usually occurs when the internal seals in the turbo leak, allowing oil to obtain the exhaust or maybe the consumption. You might furthermore notice a substantial drop in strength or a "laggy" feeling when you hit the gasoline. If your boost gauge is struggling in order to climb or if the truck seems like it's pulling an anchor, you certainly want to obtain that turbo inspected before it transmits metal shards into your engine.
Choosing Between OEM and Aftermarket
If you're in the market for a replacement, you've got a huge decision to make: perform you stay share or go aftermarket replacement? For the average person who simply uses their vehicle for daily driving and occasional light towing, a standard OEM replacement for 6. 7 powerstroke turbos is usually fine—provided it's the 2015 or more recent design.
However, if you're searching for more strength, the aftermarket world is where the particular fun starts. Brands like KC Turbos, BD Diesel, plus BorgWarner have invested years perfecting these types of setups. An automotive aftermarket drop-in turbo can provide better airflow, reduced Exhaust Gas Temperatures (EGTs), and significantly better throttle response.
The cool thing about modern aftermarket 6. seven powerstroke turbos is that many of all of them are "drop-in" replacements. This means you don't have to re-fabricate your own entire engine bay just to obtain them to fit. You can get a turbo with the larger compressor wheel that still bolts up to the factory locations, giving you an excellent push in horsepower without the nightmare of the custom installation.
Why VGT Technologies Matters
You'll hear the expression "VGT" tossed around a lot when talking about these trucks. It represents Variable Geometry Turbo. Basically, inside the exhaust housing, right now there are small vanes that proceed to modify the speed plus direction of the exhaust gas hitting the turbine wheel.
In low speeds, the particular vanes close up to create more pressure, which helps the turbo spool up very quickly. At high rates of speed, they open up enabling maximum movement. This is the reason a 6. 7 Powerstroke may tow heavy loads so smoothly compared to older vehicles. But, there's a catch—those vanes can get stuck. If you do a lot of brief trips where the engine never truly will get up to temp, or if a person idle the truck for hours on finish, soot and carbon can build-up and jam the VGT mechanism. This often leads to over-boost or under-boost rules and a truck that runs like garbage.
Increasing the Life of Your own Turbo
No one wants to drop a couple of thousand dollars on a new turbocharged before they totally have to. The particular good news is definitely that you can do a several things to keep your 6. 7 powerstroke turbos re-writing happily for the long time.
First and foremost: oil changes . The turbo spins at incredibly high speeds—sometimes over 100, 000 RPM—and it relies on a thin film associated with oil to keep the particular bearings from melting. If that essential oil is dirty or even broken down, your own turbo is going to suffer. Use a high-quality artificial oil and don't push your good luck on the modification intervals.
Minute, let the truck cool down. If you've just finished a long haul or spent an hr towing a trailer up a hill, don't just pull over and close the engine away immediately. Allow it to idle for a minute or two. This allows the oil to circulate and cool the turbo down. If you shut it off while it's glowing hot, the oil sitting inside the turbo may "cook" or carbonize, which eventually leads to bearing failure.
Thinking Regarding a Bigger Upgrade?
If you're the type of person who thinks "too much power is definitely just enough, " you might become looking at non-VGT setups or even compound turbos. Switching to the non-VGT (fixed geometry) turbo is a superb move for guys who want maximum dependability and high-end power, though you do sacrifice some associated with that low-end "snap" that the VGT provides.
Compound setups, where you have one little turbo feeding directly into a larger 1, are the gold standard for towing and performance. They give you the best associated with both worlds, but they are significantly more expensive plus complex to install. For the majority of 6. 7 owners, a durable, high-flow VGT aftermarket replacement turbo is the particular "sweet spot" for performance and drivability.
Final Thoughts
The 6. 7 powerstroke turbos are impressive parts of machinery, but they aren't invincible. Whether you're dealing along with an older 2011 design that requires an update or you're simply wanting to get a little more "grunt" from your 2022, understanding how these turbos work is half the particular battle.
Monitor your increase levels, listen intended for weird noises, and don't skip your own maintenance. These vehicles are built to function, and as lengthy as turbo charged is healthful, they'll keep pulling whatever you hook up to the hitch for years in order to come. If you finish up needing an alternative, take the time to look with your options—sometimes a small upgrade throughout a repair can make your truck think that a completely different animal.
