UPGRADE TURBOCHARGERS

Introducing Upgrade Turbochargers for the 2.9 TFSI  fitted to Porsche models.  The ultimate blend of power, fast response, and Plug&Play ease of fitment.  Our first upgrade step utilizing the original turbochargers for greater flow and power courtesy of bigger billet inlet compressors & bigger exhaust turbines and cnc milled exhaust and compressor housings to accept the larger wheels.

Performance turbochargers are designed for 700PS but there are restriction on this car example the small single charge cooler, so power of around 600-650 ps on 99ron is to be expected (WAGNER upgrade intercooler is recommended).  Upgrade downpipes, sport cats and full exhaust are recommended as upgrades to the turbo intakes and system for max performance. 

Equilibrium

Precisely balancing our turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using our single parts machine, then components are assembled and then the CHRA are dynamically balanced, but this time depending on the application at up to 250,000 RPM in multiple planes using our in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with a serial numbered balance test result document.

Turbocharged Porsche engines rely on efficient airflow and boost pressure control to deliver performance. These pressure pipes ensure that compressed air flows smoothly and efficiently through the system, helping maintain engine power and responsiveness.

What These Intercooler Pressure Pipes Do

The intercooler pressure pipes, also known as charge air pipes, carry compressed air from the turbocharger through the intercooler and into the engine.

They help:

• Maintain consistent boost pressure
• Deliver cooled, dense air to the engine for optimal combustion
• Support engine performance and throttle response
• Ensure efficient operation of the turbocharging system

Any restriction or leak in these pipes can significantly affect engine performance.

Why Intercooler Pressure Pipes Fail

Modern turbocharged engines operate under high pressure and temperature conditions. Over time, plastic charge pipes can degrade or fail.

Common causes include:

Heat and pressure stress
Repeated exposure to high boost pressure and temperature cycles can weaken plastic components.

Cracking or splitting
Plastic pipes can develop cracks, especially at joints or connection points.

Boost leaks
Seals and connections may wear, leading to loss of pressure.

Material fatigue
Over time, plastic materials lose strength and flexibility.

Symptoms of Failing Intercooler Pipes

• Loss of engine power
• Reduced turbo boost pressure
• Hissing or air leak noises under acceleration
• Engine warning lights related to boost pressure
• Poor throttle response
• Increased fuel consumption

Replacing worn or damaged pressure pipes restores proper airflow and turbo efficiency.

Why You May Need to Replace These Pipes

Restore Turbo Performance
New pipes ensure correct boost pressure delivery and engine efficiency.

Fix Boost Leaks
Replacing cracked or leaking pipes eliminates air loss in the intake system.

Improve Engine Response
Proper airflow improves throttle response and acceleration.

Prevent Further Damage
Boost leaks can cause the turbo system to work harder, leading to additional wear.

Manufactured from high-quality automotive-grade composite materials with a durable diaphragm or piston assembly (application dependent), precision-engineered internal components and high-temperature-resistant seals, the shut-off valve is designed to withstand high boost pressures, engine bay temperatures, vibration and continual operating cycles. Designed as a direct replacement for the original component, it integrates seamlessly with the turbocharger, intake system and engine management system, delivering factory-correct performance and dependable operation.  

What This Product Does:

• Releases excess boost pressure when the throttle closes.
• Prevents compressor surge within the turbocharger.
• Protects the turbocharger from unnecessary stress.
• Improves throttle response during gear changes.
• Maintains smooth turbocharger operation.
• Supports efficient engine performance and drivability.
• Restores factory boost pressure control.
• Forms an essential part of the turbocharging and intake system.

Symptoms Of Wear Or Failure:

• Loss of turbo boost pressure.
• Reduced engine performance.
• Sluggish acceleration.
• Fluttering or chattering noises from the turbocharger during throttle lift-off.
• Hissing noises caused by boost leaks.
• Illuminated engine management or check engine warning light.
• Engine management fault codes relating to boost pressure.
• Poor throttle response.
• Increased fuel consumption.
• Inconsistent turbocharger performance.

Why Replacement Matters:

• The turbocharger shut-off valve operates every time the throttle is released while the turbocharger is producing boost pressure. It is continually exposed to high boost pressures, rapid pressure fluctuations, elevated temperatures and constant engine vibration. Over time, the internal diaphragm, piston, spring or seals can wear, crack or lose their ability to seal correctly.
• A faulty shut-off valve can cause boost leaks, compressor surge and inconsistent turbocharger performance, resulting in reduced engine power, slower throttle response and increased stress on the turbocharger. Continued operation with a defective valve may accelerate wear of the turbocharger and reduce overall engine efficiency.
• Replacing a worn or faulty valve with a Genuine Porsche component restores precise boost pressure regulation and protects the turbocharging system from unnecessary wear. Manufactured to Porsche's exact engineering standards, the Genuine Porsche Turbocharger Shut-Off Valve provides factory-correct fitment, exceptional durability and long-lasting reliability, ensuring the performance, efficiency and driving experience expected from your Porsche.
