Designed to operate under extreme temperatures and rotational speeds exceeding 200,000 RPM, the turbocharger is one of the most highly engineered components within the engine. BorgWarner's advanced manufacturing processes, precision-balanced rotating assemblies and high-temperature materials ensure rapid boost response, maximum efficiency and exceptional durability.

Whether you're replacing a worn turbocharger, repairing boost-related faults or restoring factory performance, this BW turbocharger provides OE-quality fitment and uncompromising performance.

What Does the Turbocharger Do?

The turbocharger increases engine performance by using exhaust gas energy to compress incoming air before it enters the engine.

This allows the engine to:

• Produce significantly more power and torque.
• Improve throttle response.
• Increase engine efficiency.
• Deliver strong acceleration throughout the rev range.
• Maintain performance at higher engine speeds.
• Improve combustion efficiency.

The Porsche 991 Turbo's twin-turbocharged flat-six relies on precision-engineered turbochargers to deliver its exceptional performance while maintaining everyday drivability.

Why Do Turbochargers Fail?

Although designed for long service life, turbochargers can eventually wear or become damaged through:

• Bearing wear caused by high mileage.
• Oil contamination or insufficient lubrication.
• Foreign object damage.
• Excessive heat cycling.
• Oil seal deterioration.
• Carbon deposits restricting variable geometry mechanisms (where applicable).
• Overspeed caused by boost control faults.

Regular oil changes using Porsche-approved lubricants are essential for maximising turbocharger lifespan.

Symptoms of a Failing Turbocharger

Common warning signs include:

• Reduced engine power.
• Loss of boost pressure.
• Whining or siren-like noises.
• Excessive exhaust smoke.
• Oil consumption.
• Check engine light.
• Turbocharger fault codes.
• Poor acceleration.
• Boost pressure fluctuations.

Replacing a worn turbocharger restores the engine's original power delivery, efficiency and reliability.

When Should the Turbocharger Be Replaced?

Replacement is recommended when:

Bearing wear is identified. Oil seals begin leaking. Compressor or turbine wheel damage is found. Boost pressure cannot be maintained. Excessive shaft play develops. Turbocharger failure has occurred. Major engine repairs require replacement.

Replacing the turbocharger promptly helps prevent debris entering the engine or exhaust system and avoids further costly repairs.
