SRM850

The new benchmark 

in street performance 

for the 4.0TFSI 

platform.

Drop in package that includes everything you need to make up to 850WHP.

SRM850 Billet Turbochargers

Our SRM850 Billet Turbochargers are the newest and latest iteration of our +4 Turbochargers which have been proven for years on the 4.0TFSI platform to make good, reliable and responsive power. 

Extremely fast spool up with a large enough compressor wheel to flow up to 850WHP in the SRM850 package.

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 SRM850 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 well over 1000WHP on flagship and development vehicles and are the result of years of development.

SRM 4.0TFSI Port Injection Kit

Our Proprietary Port Injection Kit enables the SRM850 Package to run up to E100 and provides fuelling far beyond what the factory DI system is capable of. 

This port injection kit utilizes injection sandwich plates between the factory air duct and factory intake manifold for a drop in solution. 

Below we see the difference Port Injection makes on the SRM850 kit. The DI system topped out at 694WHP Mustang and our PI system allowing the kit to make 818WHP Mustang on this run on e60, and it is capable of flowing even more than this kit requires giving adequate overhead.

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 SRM850 package by packaging the kit with a hardened calibration developed on our development vehicles on our in house Mustang Dyno. When you use the SRM850 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.

Compatibility

• C7 & C7.5 RS7, S7, S6
• D4 S8/A8 (4.0TFSI)
• Requires DS1

Requirements

• This kit must be used in its entirety!
• Failure to do so will result in the kit not being eligible for calibration or technical support!
• Meaning : The kit must be implemented completely, and you are only to omit required parts of the kit if you already have them. Failure to adhere to this will result in you being denied support, calibration, and refund! However, if parts of the kit are omitted accidentally, please contact support and we will help you order them and regain access to calibration and support. If you omit parts of the kit, and an issue arises that could be attributed to the omission of said part in the build, we will ask you for photographs of the parts you omitted in the order installed on the vehicle before proceeding with support.
• The base of the kit, the SRM850 Turbochargers, SRM850 Exhaust manifold and SRM850 Port Fuel Injection setup is by default part of the SRM850 kit and no substitutions or omissions can be made on the core of the kit.
• The supporting modifications included in the kit, SRM Intakes, SRM LPFP, Ethanol Lines and Flex Sensor package, W2A Throttle Body Spacer, and Tial Wastegates for the 4.0TFSI, may only be omitted if you already have them! No exceptions!
• The SRM850 kit REQUIRES a DS1 for calibration. You must already have a DS1, or select one from the add-on menu. 

Notes

• A TCU Tune is HIGHLY Recommended and is available as an add-on
• Note we recommend a free flowing exhaust as the factory exhaust is restrictive and will reduce the performance of the kit. If you need an upgraded exhaust we offer a Dual 3" Exhaust solution as an add-on upgrade.
• This kit is for Off Road Use Only and should be installed by a professional.
• Requires sending in Exhaust Manifolds as cores prior or a core charge of 1000$ will be required
