APR Transverse 2.0 TFSI Valvelift K04 Turbocharger System
APR's Transverse 2.0 TFSI Valvelift K04 Turbocharger System will upgrade your current factory rated 211hp and 258lb-ft engine with all of the necessary OEM components from Audi TT-S and meticulously recalibrated Engine Management to produce 346 horsepower and 377lb-ft of torque on 93 octane gas.
Reliability, drivability, stealth and enhanced performance that cannot be bested are the highlights of APR's newest OEM-component based conversion package.
APR's engineers have expertly recalibrated the engine management system to allow for nearly flat torque delivery from 2000 RPM to 5000 RPM which results in a smooth linear pull throughout the power band. Keeping the track enthusiast in mind, this conversion package will not result in overpowering of the driveline but will allow for smooth acceleration to easily maintain control while cornering.
APR Modified K04 Compressor Cover
The Borg Warner K04 turbocharger selected by VAG engineers is perfectly sized for the 2.0 liters of displacement to allow for stout horsepower numbers as the RPMs increase with no dramatic fall off as redline approaches. This ensures plenty of power in the high RPMs for continued acceleration in the straights and positioning at the healthiest portion of the power band after corner exit.
Compact, Stealthy & Reliable Design
One of the greatest benefits to the APR K04 turbocharger system is its simple, yet elegant design. APR's CNC machined direct compressor recirculation port on the OEM compressor cover significantly reduces engine bay clutter and saves the end user from the hidden costs of purchasing extra throttle body pipes, hoses, clamps and DV mounts for recirculating boost pressure. The compact design also removes extra charge piping volume to allow for lightning fast boost response and less locations for boost leaks. Furthermore, charge air pressure is directed directly at the compressor wheel which helps keep the turbo spooled upon lifting the throttle, minimizing turbo lag.
The OEM k04 turbocharger features a turbo muffler designed to reduce turbocharger sound in the cabin that also creates a restriction in the boost pressure delivery stream. APR removes the turbo muffler not only to enhance the sound of the turbocharger, but also to smooth the airflow across the previously baffled muffler section. A clean and simple CNC flange developed by APR's Engineering Team is bolted directly to the compressor cover in place of the OEM turbo muffler. A long mounting surface provides an excellent slip proof surface for mounting the silicon discharge hose and an o-ring between the flanges ensures a life of leak proof operation.
The 2.0T Valvelift engine requires a longer PCV outlet hose for proper connection to the APR K04 Turbocharger System. APR has developed a high temperature hose solution to ensure proper PCV routing on the Valvelift without headaches. The design is clean and simple and never requires maintenance. Just remember to pick up this extra part when ordering below.
APR's EMCS Technology
Featuring APR's EMCS program switching functionality and DirectPort Programming, APR's Engine Management Calibration for this conversion package allows for a range of Octane and situation specific calibrations to be installed simultaneously on your vehicle's ECU. These programs and features are able to be cycled through via your existing factory cruise control and activated in less than 20 seconds. You will be able to choose 1 to 4 Programs listed below. You will also be able to add APR Security Lockout, APR Fault Code Erase and APR Anti-Theft features.
|Program Mode*||Peak HP||Peak TQ||Largest HP Gain Over Stock||Largest TQ Gain Over Stock||Speed Limit|
|*It is essential to ensure your vehicle is filled with at least the minimum octane rating for each Performance Calibration when activating the program.|
