Why Should You Consider Upgrading Your Duramax Turbo?
Regardless of whether you drive an LB7, LLY, LBZ, LMM, LML, or L5P, the Duramax turbo engines in those models are beasts of burden capable of performing tremendous work and have massive power potential. And if you’re beginning to tune your vehicle, tow heavy loads, or are simply seeking more horsepower, the model’s factory turbo may be a bottleneck for you.
When combined with fuel as well as air modifications, upgrading the turbo is one of the most effective ways to increase performance, durability, and improve the day-to-day usability on a Duramax engine. Let’s delve into the benefits of upgrading the turbo.
-
Stock Turbos Are Not Built to Support Excess Power Duramax OEM turbos are built to enable day-to-day uses of driving and achieve compliance with emissions but not high performance. The moment you start adding tuners, exhaust systems, or even new injectors, the factory turbo starts showing its aging gaps because of limited:
Faster spool time
Elevated exhaust EGT
Turbo bark/surge
Restricted airflow especially with huge fueling modifications
Aftermarket turbos provide solutions to the gaps mentioned far above by delivering superior airflow, boost response, and efficiency of engines.
-
Properly Support Higher Power Goals If you plan to push power targets beyond the 500 mark, the stock charger will not be able to meet your needs. Depending on the size and setup, upgraded turbos can easily handle 600-1,000+ hp.
Drop-in turbos: Excellent for mild builds with improved spool while maintaining factory fitment.
S300/S400-based turbos: Best for aggressive power targets and purpose-built track trucks.
Compound turbo kits: Outstanding low-end torque while maintaining high-end boost.
Putting the correct turbo accomplishing your goals guarantees seamless performance and easy upgrades down the road.
-
Lower EGTs and Better Efficiency
One of the most important advantages of a larger and/or more efficient turbo is lower exhaust gas temperatures. High EGTs are one of the leading causes of damage to the pistons, turbo, and overall engine deterioration.
This is severe for tuned trucks and towing situations.
-
Quicker spooling with better throttle response.
Not all upgraded turbos are laggy, although that is one common belief. A lot of newer performance turbos, especially smaller frame or ball bearing units, outperform stock turbos in throttle response and spool-up time.
You will feel:
Immediate responsiveness to throttle inputs.
Accelerating without delay.
Low RPM powerband operability.
That means a lot for a daily, street driven, or performance oriented around town builds.
-
Improve Reliability with Better Materials and Design
Performance and durability are often rolled into one neat package, but factory turbos are built only to meet cost and emission standards. Turbos designed for performance generally include the following:
- Billet compressor wheels
- Stronger bearings and shafts
- Upgraded seals
- Precision balancing
The above-listed enhancements support a higher boost threshold and are much more durable during stress, particularly when there is aggressive tuning or towing involved.
-
Unlock the Full Potential of Your Duramax
Upgrades to your turbo open up everything else you can do to your Duramax. For those of you who have done tuning, injectors, or a lift pump, your next goal should be increasing the airflow, which starts at the turbo.
Better turbos allow drivers to:
- Take advantage of custom tuning.
- Operate cleaner and cooler.
- Set the stage for future performance targets.
A better turbo allows your truck to become much more responsive when you step on the gas while still maintaining reliability.
Final Thought
If you're focused on increasing power, towing, or long term reliability, the turbo upgrade is the clear choice. The investment makes adding horsepower, reducing EGTs, and improving overall driving experience very easy.
At Tameless Performance, we try to help our clients from choosing the right turbo for their application to installing and tuning it, be it drop-in replacements or full compound kits.
