Deliver the fueling your high horsepower Audi TT RS requires with this APR high pressure fuel pump.

The 2.5L TFSI engine’s fueling system operates to a maximum of 2,100 psi (145 bar) of pressure to correctly
spray and atomize fuel directly into the engine’s cylinders. This is contrast to multi port injection vehicles of
the past which typically operated around 40-60 PSI and were driven off of a low pressure fuel pump.
To generate these enormous pressures, the 2.5 TFSI’s variable low pressure fuel pump supplies fuel to a cam
driven and solenoid fired high pressure fuel pump which in turn supplies the injectors with fuel.

A three-lobe cam located on the exhaust camshaft drives the 2.5 TFSI’s Hitachi Generation III high pressure
fuel pump. As engine speed increases, so does the pump’s ability to displace a greater volume of fuel per minute.
The maximum volume the pump can deliver per revolution on the three-lobe cam is dictated by the stroke length
from the cam lobe’s lift and bore diameter of the pump’s internal pressurizing cylinder. It’s important to understand,
despite the name, APR’s High Pressure Fuel Pump upgrade is not necessarily designed to increase the engine’s
fuel rail pressure. The primary goal is to increase the volume of available fuel.

The engine’s fueling system is very capable without modification, even at high power levels generated using APR’s
Stage II+ ECU Upgrade and exhaust. However, APR’s Stage III Turbocharger System is capable of generating
significantly more power and requires modification to high pressure fuel pump to keep up with fueling demands.

The APR High Pressure Fuel Pump addresses fueling needs and leaves plenty of headroom for safety and
further increased power levels in the future. By increasing the pump’s internal capacity, the fueling system
is capable of displacing a higher volume of fuel per minute at every RPM.
