The S400 Turbo is a Performance Legend Why You should buy one
The world of high-performance forced induction is full of turbochargers with limited amounts of respect ands established reputation as the S400 Turbo. The S400 Turbo manufactured by BorgWarner belongs to the S400SX-a series-built to satisfy the expectations of conscious sportsmen, professional racers and heavy duty demands where larger flows require high boost and bullet-proof reliability. Whether it is creating a competitive diesel pulling truck, a high-horsepower drag race car or an industrial-strength marine engine, the S400 Turbo is one of the most generation versatile and capable turbo charging platform engines you can find.
The S400 Turbo is more than an engine part, though–it is the pumping heart of some of the ballsiest most respected builds on both the track and the street.
What are S400 Turbo?
S400 Turbo is a turbocharger of large frame and is fitted on engines that utilize huge air inflow and boost. It comes in various versions, the size of the compressor wheel is between 75mm and 88mm whereas the turbine wheel size is between 83mm and 96mm. This versatility makes it useable in as little as 500 horsepower street trucks to 1,500+ horsepower competition beasts.
Its great engineering and fast compressor maps, as well as heavy duty bearings enable it to run at high boost pressures whereupon it is common to see it easily surpass 45 psi without flinching.

Basic S400 Turbo Specs
In order to comprehend the S400 Turbo in real sense, we should consider its main specification. Although specific amounts of the specs differ depending on models and trims, the following are typical specs of one of the most popular configurations:
Engineered Specs:
Compressor Wheel diameter: 75mm (on some models) to 88mm
Diameter of Turbine Wheel: 83mm96mm
Housing A/R comp: 1.10-1.32
Turbine Housing A/R: 1.15 1.32
Type of Bearings: dual or triple journal bearing
Cooling Type: Oil-lubricated (optional warm water-cooled)
Peak Horsepower: 500- 1,500+ HP, dependent on Build and parts
Max Boost Pressure: 45+ psi
Uses: Marine, industrial engines, drag racing, diesel trucks
These figures show why this S400 Turbo is perfect when a big boost and big horsepower is needed: it is designed to stand up to extreme environments that mere small turbochargers cannot hope to match.
Why S400 Turbo?
S400 Turbo is chosen by performance builders because of a number of reasons:
1. Massive Horsepower
The S400 Turbo can handle up to 500 and quite more than 1,500 horse power. When properly supported with these mods- fuel system, intercooler and tuning, it can drive volumes of air unlike the majority of the competitors can generate.
2. Proven Durability
The S400 Turbo was developed by BorgWarner to withstand severe race track demands, and high boost levels at all time. It has good journal bearings and heatproof housings, making it a long term fix to serious builds.
3. Platform Agnosticism
Whether it is Cummins-powered diesel pickups or high revving V8 drag cars, the S400 Turbo fits a vast array of engines and fuels: both gasoline and diesel as well as ethanol and methanol powered vehicles.
4. Customizable Configurations
The availability of multiple compressor and turbine wheel diameters lets you optimize the spool and turbo top-end characteristics of the turbo to your application.
S400 Turbo Performance Pros Benefits
The S400 Turbo does not simply boost the power, but it also changes the manners of behaving under the load of an engine.
Increased Top-End Power: The S400 Turbo is able to provide unstoppable power due to its large compressor wheel and high-flow turbine housing which allows the S400 Turbo to achieve powerful deliveries on higher RPM.
Enhanced Thermal Efficiency: Superior aerodynamics of the wheel allow cooling intakes down-low and make it possible to run a more free timing and fueling.
Increased Stability: The turbo maintains a constant level of boost pressure without fade, in high and extended throttle situations.
Scalability: You may begin with a smaller S400 frame and afterward upgrade to a bigger compressor wheel without replacing the whole turbo housing.
Installation of S400 Turbo
Although S400 Turbo does insanely well, it cannot be seen as a bolt-on replacement to standard factory installs. It normally necessitates:
Aftermarket Exhaust Manifold or Adapter Plate The large T6 flange needs corresponding hardware.
Custom Intake/ exhaust Piping- To the hot and cold sides of the turbo system.
High-Capacity Intercooler To cope with intake temperatures under high boost.
Enhanced Fuel System- bigger injectors, large pump fuel-high flows, and controlled fuel pressure.
ECU Tuning -Professional tuning is needed to tune boost, timing and fueling.
Diesel use has led to a compound turbo setup, where the S400 Turbo is used with a smaller (higher-efficiency) turbo to give rapid spool and huge top-end airflow.
The S400 Turbo usages
S400 Turbo can be seen in many high-performance builds, among others:
Diesel Race Trucks: Cummins, Duramax, and Power Stroke The shop makes running comp tunes.
Drag Racing: Pro-Street and Outlaw in which 1,000+ HP is normal.
Sled Pulling: Pulling competition tractors and trucks by pulling a sled where the wheels that win is the one with the most torque.
Marine Racing: Off-shore race boats that need high performance at high loads all the time.
Industrial Uses-High-rated Generators and heavy Equipment.
S400 Turbo Maintenance and life span
A turbocharger of such a level requires decent care:
Fill Up Premium Synthetic Oil-Removes bearing wear and kills heat.
Proper Oil Flow- Proper oil feed and drain lines will prevent starvation.
Warm -up and Cool-down -Give the turbo time to warm up before thrashing the car and down before turning it off.
Monitor Boost Levels – do not allow surge or overboost levels which will shorten life.
An S400 Turbo is capable of serving many years even with the competitive conditions provided that it is well taken care of.
S400 Turbo Vs Other Turbo Options
When we compare the S400 Turbo against smaller units such as S300 series, it all depends on potential horsepower and airflow. S300 is faster spooling, but limits quicker in horsepower. The S400 trades away a little spool time against the maximum power, maximum airflow.
S400 Turbo is more reliable, with more upgrade options, compared to other competing brands in the market and, therefore, tends to be a long-term investment into any serious builders.
Professionals Review on the S400 Turbo
As Ryan Greene, a Turbocharging expert comments:
The S400 Turbo is one of those phenomena, which may be met both on a 1,000-horsepower diesel truck, and in a 7-second drag car. It is flexible, reliable and can give solemn outcome when set up accordingly.”
