Unlike hand welded tubular manifolds and other cheap cast materials such as iron, Inconel is a very high temperature resistant material designed to withstand extreme exhaust gas temperature changes without expanding, contracting, melting or cracking under stress. Furthermore, the thick casting material reduces unwanted exhaust noise. This material is typically found only at the highest levels of professional motorsport racing where reliability is essential to success.

Investment-cast Inconel features heat retention characteristics, which aid in turbo response by keeping the exhaust velocity high.

A reduction in backpressure from the high-flow, collision-free design directly enhances power delivery far beyond that of the OEM turbocharger manifold and other less effective designs. Backpressure reduction also alleviates most common valve float issues associated with high output factory K04 turbo upgrades and so called small ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ__ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒ__ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒ_ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎÌ__ÌÎå«Ì´åhybridÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ__ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒ__ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎÌ__ÌÎå«Ì´å K04 turbochargers. 

Each unit undergoes strict quality control checkpoints to ensure ultimate reliability each step of the manufacturing process. The unit is CNC machined to tight tolerances and inspected for defects before being packaged and shipped to customers around the world.

All of these characteristics result in a manifold designed without compromise backed by a confidence-inspiring lifetime warranty.

  • To provide closed loop boost control at absolute pressure levels above 2.5 bar, APRÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ__ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒ__ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒÌÎå«ÌÎå´_s GTX Turbocharger System features an OEM Bosch 3 bar MAP sensor. 

Altering the ECU to understand the engine is equipped with a 3 bar MAP sensor is a trivial task. The sensor and proper calibration settings come standard on many factory VAG vehicles, but even these vehicles only provide proper closed loop boost control up to 2.5 bar absolute. 

APRÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ__ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒ__ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒÌÎå«ÌÎå´_s electrical engineers went many steps beyond the norm and recoded the factory ECU to deliver closed loop boost control up to 3 bar absolute. This ability, combined with proper torque management, results in safe, reliable, and predictable performance at higher power levels without the need for clumsy and archaic external boost controlling devices.
  • The factory engine management relies on load calculations derived from the mass airflow (MAF) sensor to properly control the engine. All too often this critical component is eliminated from turbo upgrade kits as the factory unit is small and can easily become saturated. The alternative of upgrading the unit is often not used due to the complexity of doing so. However, no task is too large for APRÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ__ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒ__ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒÌÎå«ÌÎå´_s Engineering Teams when the sake of reliability is brought into question, and as such APR has engineered a larger housing for use in the Stage III GTX Turbocharger System. 

To aid in accurate airflow readings, the APR MAF housing features a long, precision-machined tunnel with a honeycomb airflow straightener. APRÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ__ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒ__ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒÌÎå«ÌÎå´_s Electrical Engineers make appropriate coding changes to the ECU to understand the larger MAF housing while the calibration experts update the ECU with all of the necessary calibration data surrounding the larger housingÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ__ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒ__ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒÌÎå«ÌÎå´_s physical properties. The end results are accurate readings and a further refined driving experience. 

The MAF housing includes a CNC-bent mounting bracket for a sturdy connection to the engine bay and additional wiring and couplers are included to extend the factory MAF sensorÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ__ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒ__ÌÎå«ÌÎå´ÌÎÌ_ÌÎÌ_ÌÎå«ÌÎå´_ÌÎå«ÌÎå´ÌÎå«ÌÎÌÒÌÎå«ÌÎå´_s harness.
  • Wire reinforced, multi-ply silicone hoses provide an unrestricted path for airflow to enter and exit the turbocharger. The ultra rigid design ensures boost and vacuum piping will not swell or collapse causing leaks and restrictions in the induction and charge piping system supporting boost response and turbo recovery. Each hose is engineered to fit properly into the vehicle's engine bay with all necessary emissions and reference ports securely affixed.

  • The factory turbocharger features a diverter valve (DV) and wastegate solenoid (N75) directly mounted on the compressor housing, which is removed for the more powerful APR Stage III GTX Turbocharger Unit. As such,  APR provides a CNC-machined billet-aluminum DV housing and CNC-bent N75 bracket to conveniently relocate these items within the engine bay. 

The DV housing is anodized clear to protect against corrosion and the internal mounting surface is precision machined identically to the OEM unit, to ensure a proper, leak proof design.

Additional Details

In 2008, shortly after the worldwide release of the 2.0 TSI engine, Volkswagen of America commissioned APR to build the Stage III GT Turbocharger System for their SEMA concept cars. Successes of these concept cars lead to the first release of the APR Stage III Turbocharger System, based on the then available Garret GT turbocharger, and became a worldwide phenomenon. In the years since, APR has continued to work with VWoA, Volkswagen GmBH, VWVortex and BFGoodrich to deliver more concept cars for SEMA, Wörthersee in Austria, as well as other events around the world, while APR continued testing the latest in turbocharger technology.

With the introduction of the Garret GTX2867R Turbocharger, APR has raised the bar further and redefined the standard by which the VAG community measures performance, reliability, drivability and quality. Gone are the days of compromise where low-end response meant excessive backpressure, compressor surge, and extremely limited top end performance. True to APR’s mantra of Performance without Compromise the days of shredding tires on front wheel drive vehicles are rapidly disappearing thanks to the new Gold Standard in ECU torque management calibration strategies only APR can deliver. APR’s endless pursuit of perfection has resulted in the most comprehensive 2.0 TSI turbocharger system in the world.

The 2.0 TSI is completely transformed the second it meets an APR Stage III GTX Turbocharger System. Power immediately jumps to 423 horsepower with 387 ft-lbs of torque on tap using 93 octane fuel on a completely stock and unmodified factory fueling system. Switching to APR’s 100 octane race fuel mode, power shoots up to 458 horsepower with 409 ft-lbs of torque all at the driver’s command. This level of extreme performance is just a taste of the system’s full performance capabilities. APR’s Stage III+ GTX fueling system (Coming Soon!) increases performance further by simply adding a few bolt-on APR fueling components.

Horsepower and Torque was measured in APR’s in-house, soundmaster dyno cell, using a dynapack all-wheel dynamometer. Multiple stock and modified runs were conducted and the SAEJ1349 corrected results were averaged together to represent the differences between a stock and APR Stage III GTX 2.0 TSI. Crank power figures were estimated based on VAG’s factory advertised results.

Requirements and Recommendations

  • Intake System
    The Carbonio Stage I Intake System is required.
  • Exhaust System
    The APR Midpipe Exhaust System is required if the vehicle is not currently equipped with the Downpipe Exhaust System or Turboback Exhaust System for maximum performance.
  • Intercooler System
    The Intercooler System is required to meet the advertised power figures.
  • Transmission
    The APR Stage III GTX Turbocharger System greatly increases torque over the factory output levels and as such, an upgraded clutch may be necessary to transmit power to the ground. APR highly recommends upgrading the factory clutch to one that suits the operator's intended driving style.
  • Engine Internals
    For increased reliability and longevity, especially on vehicles running race fuel and heavily tracked, APR recommends Connecting Rods and Mahle Pistons.
  • Tires
    APR recommends Michelin PSS and PS2 tires as well as BFGoodrich Rivals and GForce Sport Comp 2 tires.
  • Fluids
    APR recommends Motul Fluids and Lubricants.

The factory Bosch MED 17 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

With the significant amount of changes included in the APR Stage III GTX Turbocharger System, APR’s Engineers spent months calibrating the engine management system, including hundreds of hours of in-house chassis dyno development. Drivability, gear changes, cruising and part throttle operation were tuned to operate smoothly as if intended by the OEM through proper torque management. Further development was performed putting the vehicle through performance evaluation and durability testing at the drag strip and road course. APR’s Electrical Engineers built new coding functions, strategies and routines into the ECU to control conditions normally unseen at factory power levels. Thanks to APR’s incredible proprietary calibration suite, data logging software and full access to the coding structure of the ECU, appropriate and intelligent changes are made to ensure flawless drivability and excellent performance without compromise.

Engine Calibration:

APR’s Calibration Engineers properly restructured the engine’s volumetric efficiency (VE) model to properly determine the ECU’s calculated load and deliver proper torque management. Thanks to APR’s patented boost control coding and the addition of a 3-Bar MAP sensor, the ECU is able to perform closed loop boost control well beyond relatively low limits dictated by the factory MAP sensor. This directly translates to safer and more predictable operation while additionally producing more power and torque across the entire power band.

Additionally, through the properly reconstructed VE model, accurate open loop fueling is achieved, translating to insignificant fuel trim adjustments.  Closed loop fueling is calibrated to control lambda perfectly under all operating conditions.    Furthermore, compensations, such as ones related to intake air temperature, exhaust temperature, and altitude, are adjusted to handle the larger variances compared to the factory, low output setup.

APR’s Calibration Engineers have optimized cam timing, ignition timing, engine load and lambda to provide tremendous leaps in power while retaining the OEM knock control strategy. The result is safely achieved power, optimized for various fuel grades found around the world from low quality pump fuel, all the way to high quality, oxygenated race fuels.

Torque Management and Traction Control:

Torque management plays a big role in how the vehicle feels and performs, especially during moments of low gear, rapid acceleration. Typically front wheel drive vehicles suffer from excessive wheel spin during these moments due to the massive torque on tap from the Stage III GTX Turbocharger System. Some drivers can find themselves in situations where they are fighting against wheel spin and traction control when they are simply interested in going forward as quickly as possible. This is further compounded by the fact the factory traction control (ASR) system was designed for vehicles producing far less power and torque, resulting in overcompensated ASR interventions.

APR’s Calibration Engineers set out to perfect torque management and traction control by minimizing wheel spin as much as possible without neutering the driving experience. A multi step approach was taken to achieve appropriate control. With ASR enabled, forward movement wheel spin will trigger appropriate torque intervention levels to minimize spin without hurting forward acceleration. On top of this, the torque management system is fine tuned to deliver only as much torque as the tires can take. In normal conditions the tires will only slightly break loose under full acceleration, resulting maximum acceleration. In higher traction situations, or with ASR disabled, all of the system’s torque is directly on tap!

While the end goal is similar, APR’s torque management system differs greatly from archaic “boost-by-gear” strategies. “Boost-by-gear” strategies rely on a static limitation of boost in an effort to minimize wheel spin, but to work properly they must be dialed in for every situation. The same boost levels in different weather conditions, such as a hot summer day and a cold winter month, can produce vastly different torque levels. Since APR’s torque management system relies on the engine management’s phenomenal torque reporting abilities, it is able to adjust to every environmental situation it encounters. To achieve a targeted torque level, the ECU applies the appropriate changes to mass airflow and ignition.

Acceleration Enhancements:

Through further calibration changes APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle. Ignition delays are reduced resulting in a more responsive pedal without altering overall throttle sensitivity and resolution. Drivability was greatly improved by reducing the throttle lag commonly noticed at slow speeds and while reapplying throttle after decelerating. APR’s Motorsport Rev Limiter allows power to climb all the way to redline without dropping off several hundreds of RPM earlier. Lastly, APR’s tried and tested Motorsport Launch Limiter allows the driver to focus on launching the vehicle, rather than controlling the engine speed.

Part Throttle Drivability:

Beyond wide open throttle performance, APR’s Calibration Engineers spent countless hours optimizing vehicle drivability under daily, part-throttle, driving. The vehicle fully retains its impressive daily driver status and simply has more power on tap should the driver request more with his or her right foot!

APR EMCS and APR Mobile:

APR’s EMCS program switching technology and APR Mobile put control of the ECU in the operators hand to access modes for standard pump fuel, high output race fuel and even reduced output valet modes to protect the vehicle against improper use by other individuals. This technology is patented by APR and is found nowhere else in the world. It’s Performance Without Compromise only APR can deliver!
