Product Details

Description

The APR K04 Turbocharger System offers a substantial leap in power and torque all with excellent response in a reliable and stealthy, compact design. Expect lightning fast response, smooth daily driving and power that transforms the vehicle into a new class of enjoyment.

Design:

The integrated turbofold design features a cast stainless steel exhaust manifold and turbine housing, integrated into one single unit. This design aids in turbocharger spool while the stainless steel construction is capable of withstanding higher exhaust gas temperature for longer periods of time than lesser materials, such as cast iron. The CNC-machined, billet aluminum compressor wheel and higher flow exhaust turbine wheel expand the turbo’s efficiency range, allowing for higher output across a wider RPM range.

Power:

Unlike the factory turbocharger, power stays strong and doesn’t dramatically taper towards the vehicle’s new 7,100 RPM redline.

Power numbers look like for each mode:

  • 91 Octane- 360HP 346 LB-FT 
  • 93 Octane- 382HP 360 LB-FT
  • 100 Octane- 408HP 375 LB-FT

Turbocharger:

  • Integrated DV Adapter

    • The compact design also removes extra charge piping volume to allow for faster 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.
  • Turbo Outlet and Turbo Muffler Removal

    • APR removes the turbo muffler not only to enhance the sound of the turbocharger, but to also provide a smooth airflow path across the previously baffled muffler section
  • PCV Blockoff Plate

Engine Management

  • APR’s Calibration Engineers restructured the engine’s volumetric efficiency (VE) model to correctly 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

Compressor Surge Avoidance:

  • To aid in turbocharger reliability and longevity, APR’s engineers carefully studied the turbocharger’s compressor maps to avoid regions where compressor surge may be experienced. The K04 turbocharger has fantastic response characteristics and is able to produce incredibly high pressure at low airflow levels, but in doing so, the turbocharger runs into issues of compressor surge. In the area between 3000-4000 RPM, APR’s Calibration Experts have elected to limit boost pressure. During testing, with the limits removed, APR’s engineers were able to easily achieve over 400 ft-lbs of torque with 93 octane fuel, but doing so could result in damaging the turbo’s reliability. Back-to-back testing was conducted with and without the limitation and despite the reduction in torque in this range, APR’s engineers were unable to record a measureable difference in accelerative performance.

Torque Management and Traction Control:

  • 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. 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!
