ADDED DISPLACEMENT

Your HPFP is an integral part of the B9 3.0T & 2.9T platforms direct injection (DI) system and provides exceptionally high-pressure fuel (exceeding 2900psi) to the injectors. When running turbo upgrades or ethanol fuel, the stock HPFP internal volume becomes the limiting factor when increasing power. IE's HPFP internals install into your factory pump housing and increase the bore and piston size of the pump internals, adding more flow, delivering more fuel, and safely allowing for higher horsepower & torque output.

FLOW TESTING

IE HPFP Upgrade Internals offer the largest possible size within the B9 V6 pump body. The factory-installed 9.92mm internal pin has been enlarged to 11.68mm, increasing the stroke volume from 448mm^3 to 621mm^3. The result is a maximum gain of 38.58% more flow over stock!

CUTTING-EDGE RELIABILITY

Every piston and cylinder is CNC machined to exacting sizes, assembled, and measured as a matching set in-house. Tolerances are hand-verified using specialized measurement tools and verified down to 0.00005 of an inch to ensure reliability and proper function. These extreme manufacturing and QC processes have built IE's leading reputation in HPFP reliability and cemented our HPFP designs as the popular choice for those requiring a worry-free operation.

PUMP DYNO VERIFICATION

IE HPFP designs are verified and torture-tested on our fuel pump dyno. This machine can replicate countless miles and various RPM situations to substantiate every detail of the HPFP design. This strict engineering process, combined with our 100% in-house CNC machining, obsessed quality control, and top-shelf components, is why IE HPFP Kits have earned their reputation for reliability.

INCLUDED LIMITED WARRANTY

Due to the extreme machining and coating tolerances, Integrated Engineering is proud to offer a limited warranty on this product:
Unlimited miles for 12 months from the day of purchase

DLC COATED

DLC (diamond-like carbon coating) is an advanced coating process applied to the tool steel pin. This coating reduces friciton by combinig increased hardness with low coefficient properties to providing excellent wear and a self-lubricating behavior that drastically extends pin life.

TITANIUM RETAINER

Our ultra-lightweight FEA-optimized titanium retainer reduces the chance of valve float while securing the factory spring to the new IE pump assembly. The internal kit is designed correctly for the factory spring rate, avoiding the need for a stiffer spring that adds unnecessary pressure and wear on the camshaft.

NITRIDED CYLINDER

The HPFP cylinder is tortured with up to10,500 strokes per minute with an extremely narrow tolerance and lubricated solely by fuel. To ensure durability, we have manufactured a tool steel cylinder featuring an advanced nitriding finish. This procedure infuses nitrogen atoms into the material's outer surface, greatly enhancing the surface hardness and wear resistance. Each nitride cylinder is independently verified for thickness and quality in a specialized laboratory.

INSTALL TOOL

Disassembly & assembly of the factory HPFP housing requires a specialty tool to thread the assembly housing into the pump body. We have designed and manufactured ours to fit directly to 1/2" drive sockets and torque wrenches. This offers better leverage for unthreading the body and reliable torque spec to complete the installation process without any hassles, making the job easy.

HPFP Socket Tool sold separately

INSTALLATION

Installing your new HPFP kit is straightforward with the correct tools and does not require any permanent modifications. Involves fuel lines and special care to avoid contamination in a clean environment; experienced or professional installation is highly recommended.

Install time around 2-3 hours

HPFP Internal Upgrade

Very inexpensive way to run E85 and get an extra “100 lbs. of torque.” I retuned my S5 to stage 1+ and I could feel the torque difference in 2nd and 3rd gear. I’m extremely happy with it, but I know it will be a beast with stage 2 TCU upgrade. That’s the next thing on my list.

Stage 2+ worth it

The part is not too bad to install. The value rating is highest marks due to the claimed manufacturing process.

The resulting tune at Stage 2+ 91 octane (running 92 pump fuel) with TCU Stage 2 has a noticeable increases in power, more so than I was expecting. The car is so good now I might not upgrade the turbo which was my overall goal. Nice work, IE!
