APR B8 3.0 TFSI Supercharger
Coolant Performance System
APR is pleased to present a completely
reengineered supercharger Coolant Performance System (CPS) for the Audi B8 3.0
TFSI. Through extensive motorsport
testing in GRAND-AM Road Racing, APR?s
Engineering Team discovered the OEM
supercharger cooling system was inadequate at higher boost
pressures and power levels and therefore developed the APR CPS to improve both
performance and reliability.
Performance
Compressing incoming air such as all superchargers and
turbochargers do to deliver increased volumetric efficiency and
thus more power at every point of combustion creates heat that must
be properly cooled again prior to entering the cylinders. Most all
automotive enthusiasts have experienced this with even normally
aspirated cars whereas in the cool winter days our cars clearly
perform better than in the hot summer months. When increasing
engine power or during spirited driving, and especially during
brutal motorsport racing, the OEM
supercharger cooling system quickly becomes taxed, creating a loss
of engine performance.
Reliability
Heat is a major concern regarding the health of your engine and
APR pays close attention to reliability.
The engine?s ECU takes many steps to
reduce power output when temperatures rise, however it can only go
so far. By reengineering the supercharger cooling system,
APR is able to not only keep performance
consistent but also ensure your engine is more reliable by having
done so.
APR 3.0 TFSI Supercharger Pulley Upgrade
APR is pleased to present the world?s
first Supercharger Pulley and corresponding ECU Upgrade for the 3.0 TFSI. 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!
APR has chosen not to cut any corners
and as such each APR Supercharger Pulley
Upgrade Kit includes a new supercharger belt. Furthermore, all
existing APR Stage I ECU Upgrade customers are entitled to a free
APR Stage II+
ECU Upgrade required for proper
functionality. Finally, every APR Pulley
is E-Coated black for an OEM
appearance.
