IE HPFP Upgrade Kit For Audi C7/C7.5 4.0TT S6, S7, & RS7 - IEFUVP1

$879.99

LEADING FEATURES

  • Two sets of HPFP internal kits to upgrade your stock pumps
  • Reliably adds a larger fuel ceiling for increased flow
  • Piston diameters increased to 11.67mm
  • Largest stroke volume available
  • Broken-in and bench tested on in-house pump dyno
  • Constant diameter piston design for long-life operation
  • Retains OE spring & retainer to avoid increased camshaft wear
  • Tool steel DLC coated pin
  • Nitrided tool steel cylinder
  • Molybdenum disulphide impregnated leak-free seal
  • Stainless steel seal body
  • Buna-N rubber oil resistant o ring
  • Individually tested and verified for extreme tolerances

ADDED DISPLACEMENT

The 4.0TT's high-pressure fuel pumps supply high-pressure fuel (exceeding 2900psi each) to the direct-injeciton fuel system injectors. When running turbo upgrades, especially with ethanol fuel blends, the stock HPFPs internal volumes become a limiting factor when increasing power. IE's HPFP internals install into your factory pump housings and increase the bore and piston size of the pump internals, allowing more flow, delivering more fuel, and allowing for more horsepower & torque from your hardware and tuning upgrades.

 

FLOW TESTING

Flow testing was performed to measure the increase in flow rate which produced a maximum result of 38.58% gain over stock!

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.

Engineered & manufactured in the USA

 

INCLUDED LIMITED WARRANTY

Due to the extreme machining and coating tolerances, Integrated Engineering offers a limited warranty on this product:
Six months from the day of purchase (unlimited miles) for 4.0TT internal HPFP kits.

 

CONSTANT DIAMETER PIN

Many aftermarket HPFP options use a stepped-diameter piston in a cost-saving effort to reuse the already weak and problematic factory seal. A stepped design dramatically reduces the contact between the pin and cylinder, causing instability of the pin stroke leading to increased wear. IE assemblies use a constant diameter pin which maintains its larger size through the entire piston shaft. This engineering detail increases the contact between the pin and cylinder by over 50%, increasing pin stability and an even greater displacement.

DLC COATED

DLC (diamond-like carbon coating) is applied to the tool steel piston to increase surface hardness, reduce friciton, and provide excellent wear resistance from it's self-lubricating properties. This advanced coating drastically extends piston and pump life.

 

NITRIDED CYLINDER

The pin cylinder is subject up to 19000 strokes a minute and is lubricated by fuel only. To provide long life and withstand this torture, our tool steel cylinder is nitrided. This advanced process infuses 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 cylinder is independently verified by a specialty lab.

LEAK-FREE SEAL

A CNC machined stainless steel pump body holds our molybdenum disulphide seal, which is ideal for reducing friction and maintaining stiffness. The seal is spring energized to increase reliability and provide constant outward pressure. The body is sealed to the pump with a quality Buna-N (acrylonitrile butadiene) rubber o ring, ensuring it will hold up against heat and a wide range of fuels. What may seem like minor features add up to ensure long life and trouble-free operation.

 

PUMP DYNO BREAK-IN

Our Audi C7 4.0TT HPFP designs are verified and torture-tested on our own application-specific fuel pump dyno. This machine is able to 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 esteem and reputation for reliability.

 

HPFP 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 socket and torque wrenches. This offers better leverage for unthreading the body and reliable torque spec to complete the install process without any hassles to make 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

My part doesn't have a fitment guide.

We're so sorry about that, but we're working on it! We list over 100,000 SKUs and we're updating them daily. Some products are uploaded without the fitment guides being built out. If you're unsure about product fitment, please email us via support@exoperformance.ca.

  • How do I know if you have an item in stock?

    In-Stock Products

    In Stock

    Items marked as "In Stock" are physically in our facility, so they're ready to ship when the order is placed. If all items in your order are "In Stock", then your order typically ships within one business day.

    Other Availability Modes

    We use several availability modes to most accurately identify when products will leave their home facility:

    Direct Ship This product is available and will be sourced from one of our suppliers. It may take up to three business days before it ships.

    Warehouse Transfer We receive the item, then we ship it to remain on time with the guaranteed delivery range chosen at checkout. It typically takes between 6 and 12 business days before it ships.

  • How do I know if a part will fit my car?

    We update our catalog daily to provide the most accurate fitment information possible. When shopping for parts, please use the “select your vehicle” car selector on the home page. Once you've selected your car, you can filter parts specific to it.

    Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.

    Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".

  • What is a core charge?

    A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.

  • What is MAP pricing? Why can't I get a discount on a MAP item?

    "MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
