Take the next step in your BMW S55 build with the PureTurbos Pure700, a high-performance turbocharger upgrade engineered for the 3.0L S55 twin-turbocharged inline-6 found in the F80 M3, F82/F83 M4, and F87 M2 Competition and CS.

Designed for enthusiasts pursuing substantially more power than the factory turbochargers can provide, the Pure700 combines upgraded compressor and turbine components, reinforced turbocharger internals, precision VSR balancing, and an OEM-design housing for a direct-fit installation. With the appropriate fuel system, supporting modifications, and custom ECU calibration, the Pure700 is designed to support 700+ WHP.

Built for 700+ WHP

The PureTurbos Pure700 is engineered around increased airflow capacity and durability for high-output S55 applications.

Its upgraded billet compressor wheel and high-flow turbine wheel are designed to move substantially more air than the factory turbochargers while improving the turbocharger's ability to support increased power at higher engine speeds.

With the appropriate supporting hardware and calibration, PureTurbos rates the Pure700 as capable of supporting 700+ wheel horsepower. Actual results will depend on factors including fuel type, engine condition, supporting modifications, boost levels, and ECU calibration.

Upgraded Billet Compressor and High-Flow Turbine

At the core of the Pure700 upgrade are its revised compressor and turbine components.

The billet compressor wheel is designed to provide increased airflow capacity for high-performance S55 applications. On the exhaust side, the high-flow turbine wheel is engineered to efficiently handle the increased exhaust flow associated with higher power output.

Together, these components provide the airflow capacity necessary to move beyond the limitations of the factory S55 turbochargers.

Heavy-Duty CHRA for High-Boost Applications

The Pure700 features an upgraded CHRA (Center Housing Rotating Assembly) designed for the increased demands associated with higher boost and power levels.

The upgraded center assembly complements the larger compressor and turbine components, providing a more robust foundation for a high-output S55 turbocharger setup.

VSR High-Speed Balancing

PureTurbos uses VSR high-speed balancing technology to precisely balance the turbocharger assembly.

High-speed balancing is particularly important for performance turbochargers operating at elevated rotational speeds. Proper balancing helps promote smooth turbocharger operation and supports long-term reliability under demanding conditions.

OEM-Design Housing and Direct-Fit Installation

The Pure700 utilizes a new OEM-design aftermarket housing engineered around the factory S55 turbocharger configuration.

This allows the Pure700 to retain a direct-fit design for compatible BMW applications rather than requiring a completely custom turbocharger installation.

However, modification or removal of the factory turbocharger heat shields may be required to achieve proper fitment. Always review the supplied fitment guide before installation.

Custom ECU Tuning Required

The Pure700 is a significant turbocharger upgrade and custom ECU calibration is mandatory.

The increased airflow capacity of the Pure700 requires appropriate tuning to properly control boost, fueling, ignition, and other relevant engine parameters. Custom calibration is also essential for taking advantage of the turbocharger's increased power potential while maintaining appropriate engine operating parameters.

The advertised 700+ WHP capability should not be considered an out-of-the-box power figure. Achieving this level requires an appropriately prepared vehicle with the necessary fuel system, supporting modifications, and custom tuning.

Supporting Modifications

A Pure700-equipped S55 should be treated as a complete performance system rather than an isolated turbocharger upgrade.

Depending on the desired power level and fuel being used, supporting modifications may include:

• Upgraded fuel system
• Appropriate intake and charge-air components
• Upgraded intercooling
• Exhaust-flow improvements
• Custom ECU calibration
• Appropriate spark plugs and ignition setup
• Additional supporting engine hardware as required by the target power level

The exact supporting configuration should be determined by the tuner based on the vehicle, fuel, target output, and intended use.
