Want more power and performance from your 3.0T supercharged engine?

Without recalibrating the ECU found in Audi’s latest line of supercharged direct injected vehicles, pulley upgrades offer
no advantage, as the supercharger will simply bypass boost pressure. With APR’s ability to expertly recalibrate the 3.0
TFSI Engine Control Unit, we are able to develop new hardware and calibrate the ECU to work properly as if intended
by the factory.

Many enthusiasts coming from Audi’s history of turbocharged vehicles expected massive increases in torque, at lower
RPMs, simply by adding an ECU Upgrade. Unlike turbochargers, roots style superchargers are positive displacement
meaning they provide a fixed amount of air flow based on engine speed.  On the 3.0TFSI Audi chose to use a bypass
valve that bleeds off boost pressure when requested.  Keeping the valve almost completely shut at lower RPMS allows
them to make respectable torque, and, opening the valve at higher RPMs allows them to keep horsepower within their
marketing goal. Consequently, the APR Stage I ECU upgrade provides a relatively low increase in torque but an
exceptional increase in power.  For those demanding more torque, The APR Supercharger Pulley Upgrade is the answer.
Spinning the supercharger faster increases air flow and effectively doubles the low-end gains of Stage I. The gain in
 torque is felt immediately, but the results are present from beginning to end adding up to 80ft-lbs and 108
 horsepower at all four wheels!

*All existing APR Stage I ECU Upgrade customers are entitled to a free APR Stage II+ ECU Upgrade required for
 proper functionality.

Increasing Supercharger Speed:

The 3.0 TFSI uses an Eaton Twin Vortices Series (TVS) Roots-type Supercharger unit, which features a four-lobe rotor
design to safely run at high operating speeds. APR's no stranger to the Eaton TVS1320 Supercharger Unit having spent
several years developing a Stage III Supercharger System for the High Revving Audi RS4 and S5 4.2L FSI V8. Through
the years, APR's Engineering Teams placed even greater speed demands on the TVS1320 than offered to the public with
a flawless track record.

A balance of power and reliability is always a concern when going beyond what Audi delivers from the factory and APR's
Engineering Teams use accelerated life testing both in house and through professional motorsport racing to ensure years
of Performance Without Compromise.

Increased Boost Pressure:

Unlike turbochargers, superchargers boost pressure is nearly fixed in relation to engine speed. The factory supercharger
unit features an electronically controlled bypass valve which bleeds off boost pressure when mass airflow and load levels
increase past the power requirements set from the factory. The APR ECU upgrade prevents boost from bleeding back into
the intake system, resulting in higher boost levels. However, boost pressure is still limited by the size and the speed of the
supercharger.

The APR Supercharger Pulley Upgrade increases the RPM of the supercharger resulting in an increase of boost pressure
all the way to redline. This results in torque you can feel off idle all the way to redline.

For max performance, Pair this pulley with the larger, 187mm crank pulley and with APR's Ultracharger System.
