Dual Brushless LPFP for up to 1000hp on Ethanol

Backordered- 5 to 6 week lead time. 

Dual Brushless Low Pressure Fuel Pump kit to support over 1000 horsepower using full ethanol on the C7 chassis with 4.0TFSI engine.

***NOTE: MUST RUN INLINE EXTERNAL FUEL FILTER***

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.5T EA855 EVO (Gen 2) engine!

APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 2.5T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install. Optional features, such as APR's EMCS Program Switching and APR Mobile are available. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!

Upgrade your direct injection high pressure fuel pump for dramatically more fuel volume needed on high powered applications.

This Low Pressure Fuel Pump for the D4 chassis covering the A8 and S8 models, adds a second brushless pump in the tank. The kit includes billet bulkhead, pump hanger, SRM secondary brushless controller, wiring harness with provisions for 8AN lines.

This S8 LPFP requires the 4.0 TFSI Fuel Line kit below for installation (OR any 6an engine bay line kit) The optional inline filter and AN fittings relocate the factory filter to the firewall due to limited tank space.

This kit will support up to roughly 1600hp on gasoline and 1200hp on ethanol.

* Designed to work seamlessly with the factory ECU calibration, however may require custom tuning to run without faults and deliver the proper fuel flow/pressure under all conditions ANY COMPETANT TUNER (LOADLOGIC, C4TUNING)

Port Injection Setup for the C7 4.0TFSI Platform

Turbochargers

Our SRM1K Billet Turbochargers are the result of years of research and development bringing the ultimate drop in Turbocharger solution to the 4.0TFSI platform. These have been powering our Flagship and Development vehicles for years.

Limitless top end with mind numbing boost numbers.

Why Xona? It's simple. They're USA made, rebuildable, and offer the highest possible performance in this form factor. Xona Turbochargers power our flagship and R&D vehicles making upwards of 1200WHP.

SRM Air to Air Intercooler with 

Integrated Port Injection

One of our flagship products, and first to market in the 4.0TFSI world, the result of years of development and iteration, is the 4.0TFSI A2A with Port Injection offering from SRM. 

This gorgeous piece has billet CNC end tanks, a large core, and integrated port injection via billet CNC snouts. This is the crown jewel of any 4.0TFSI and is every bit as functional as it is stunning. 

The A2A keeps charge temperatures low during a pull, and the Port Injection integration allows use of ethanol concentrations up to E100.

SRM 4.0TFSI Exhaust Manifold with 

Integrated Turbine Housing

Our Upgraded Exhaust manifolds with Integrated Turbine Housings alleviate cylinder 5 miss-fire issues due to excessive back-pressure often experienced by people running stock exhaust manifolds and allow the engine to exhale freely thereby alleviating the major bottleneck in the 4.0TFSI engine. 

The upgraded exhaust manifolds are an integral part in the SRM1000 kit allowing the package to reach such high power output by flowing significantly more than the factory exhaust manifolds without sacrificing the extremely responsive spool that the 4.0TFSI is known for. 

These same exhaust manifolds are proven on flagship and development vehicles and are the result of years of development.

SRM 3" 4.0TFSI Intakes

The big brother of our SRM 4.0TFSI Intakes, the SRM 3" Intakes, are a requirement, allowing the Turbochargers to breathe well and are a significant upgrade over the stock intakes which are a known bottleneck on this platform due to their restrictive design. The inclusion of the A2A in this kit allows the larger intakes to fit.

SRM 4.0TFSI LPFP Upgrade

Essential to deliver enough fuel to the Factory Direct Injection and Port Injection System to achieve these power levels is the SRM 4.0TFSI LPFP Upgrade. 

Proven dual LPFP solution that we have offered for years. These kits are extremely reliable and provide the heavy lifting for fueling the SRM1000 package.

DS1 Software Calibration

Before today the standard in the 4.0TFSI community has been piecing together parts that then require custom tuning which is a headache and has mixed results. Hardware variance and lack of access to a Dyno for most custom tunes provides limited and inconsistent results. Dealing with custom tuners can be time consuming and expensive. Tuning without a Dyno and a tuner present to monitor the vehicle can be dangerous and expensive. We have addressed these issues based on feedback from our Customers and the Community in the SRM1000 package by packaging the kit with a hardened calibration developed on our development vehicles on our in house Mustang Dyno. When you use the SRM1000 kit, the calibration is already done. The tune is hardened and ready to use out of the box.

It's as simple as it is powerful.

Flex Fuel Capability

Our Flex Fuel System, Port Injection System, and LPFP upgrade, when used with DS1, allow you to fill up any ethanol percentage from E0-E100. No more worrying about overstressing your fuel system with high ethanol concentrations. This kit addresses fuel flow completely, allowing you to just fill up with Flex Fuel and enjoy your car. Simply fill up with any concentration of Ethanol, and the Calibration in conjunction with the hardware will account for your ethanol concentration seamlessly, adjusting power output accordingly to a given concentration of Ethanol.
