IE's HPFP complete pump upgrade for the Audi 3.0TFSI Supercharged engines is a completely assembled bolt-on high-pressure fuel pump upgrade. The new OEM fuel pump housing is meticulously assembled with our USA-engineered and manufactured high-flow internals that will reliably provide enough fuel system pressure for dual pulley ECU tunes to provide enough flow for ethanol fuel blends. The 11.67mm piston is the largest sized diameter possible within the fuel-pump body.
Your HPFP provides extremely high fuel pressure (exceeding 1500psi) to the direct injection system on your Audi 3.0T supercharged engine. Fuel output and ultimately power is limited by the internal displacement of the pump. By increasing the bore and piston size of the pump internals, the HPFP upgrade is capable of producing much more flow. This higher-output HPFP design offers the fuel increase needed for those running Stage 2 Dual Pulley setups and looking to run higher octane fuels for aggressive race and track style driving.
The internal assembly of your HPFP is a delicate balance of astonishingly high pressure and extremely delicate tolerances. Every piston and cylinder is a match set CNC machined to exacting sizes. Tolerances between the two are hand-tested using precise measurement gauge tools and verified down to 0.00005 of an inch! These tolerances are required due to the maximized size of our pump assembly and absolutely critical for HPFP reliability and function. Even the smallest contamination can cause pump wear or failure, to ensure this each pump is assembled in a clean environment with a Laminar flow hood. This is why IE only sells HPFP pumps fully assembled in new OE housings as to ensure reliability.
The piston & cylinder engineered for HPFP upgrade is a constant diameter design; meaning it maintains the outer size through the entire piston shaft. This ensures no displacement change occurs on the bottom side of the piston and protects against pressurized pulses against the shaft seal. After testing many pump designs, IE engineers determined this feature necessary for long reliable pump operation. Be wary of pump designs with a stepped diameter engineered to use the factory seal as a cost saving design. We have found these units reduce the contact between the pin and cylinder by over 50% which greatly increases wear, pin leakage, and instability of the pin.
DLC (diamond-like carbon coating) combines hardness and low friction, providing excellent wear properties and self-lubrication behavior that drastically extends the life of the tool steel piston.
The cylinder can see up to 19000 strokes a minute and is lubricated by fuel only. Our tool steel cylinder is infused with nitrogen atoms into the atomic structure of the outer surface of the component, increasing surface hardness and wear properties drastically. The thickness and quality of every nitride production batch are independently verified in a specialty lab.
To prevent fuel leaking past the HPFP seal and into the crankcase, our HPFP upgrade includes a molybdenum disulphide seal used for it's stiffness and reduced friction characteristics. To further reduce the chance of failure, the seal is spring energized to provide constant outward pressure, even as the seal ages. What may seem like a small feature -in reality provides a reliable and long-life HPFP upgrade.
Every IE internal kit is run on our own application-specific fuel pump dyno to verify proper function and break-in before being packaging. This strict QC process, combined with our 100% in-house CNC machining and top-shelf components, is why IE HPFPs have earned their rock-solid reputation for extreme reliability.
