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

4.0TFSI Drop in exhaust manifold with turbine housing. This is a direct drop in replacement for the extremely restrictive factory exhaust manifold. 

These alleviate the cylinder 5 missfire issue by reducing EMAP caused by the extremely restrictive factory manifolds.

Horsepower increases of 50+ horsepower depending on setup. With larger turbos expect significantly more.

These uncork the main performance bottleneck of the 4.0TFSI engine by allowing the engine to exhale properly making the engine significantly more efficient because it doesn't have to work as hard to pump exhaust out of the engine. Not only will you have the exhaust flow to make more power, you will make that power more efficiently reducing strain on the engine by reducing backpressure.

Compatible with Factory Downpipe

These are an essential upgrade for anyone looking to make real power on the 4.0TFSI engine. 

These manifold turbine assemblies are sized to fit all drop in turbos, including S7, RS7, +4, TS1, etc.

They are available for larger turbine turbos as well in the drop down menu, including Xona, TS2* and TS2+*.

CORE CHARGE OF 1000$ USD.

BROKEN DOWNPIPE BOLTS/STUDS WILL FORFEIT 250$ OF THE CORE FEE 

Send us your factory manifolds for a core credit of 1000$ off your purchase!

You must send in your manifolds before we ship!

Alternatively, you can pay full price, and when we receive your good core, we can refund the core charge of 1000$!

*NOTE for TS2 and TS2+ turbos, you must send us your manifold core prior to production and we do not offer a no core option for these turbochargers.

4.0TFSI EXHAUST MANIFOLDS ONLY!

These alleviate the cylinder 5 misfire issue by reducing EMAP caused by the extremely restrictive factory manifolds.

These drastically improve the volumetric efficiency of the 4.0TFSI engine.  Not only will you have the exhaust flow to make more power, you will make that power more efficiently reducing strain on the engine by reducing backpressure.

These are an essential upgrade for anyone looking to make real power on the 4.0TFSI engine. 

These manifolds are perfect for single turbo fabrication!

Part Numbers:
EVE-A90-CF-INT : Toyota MK5 Supra Carbon Intake

Performance Gain: 17-20hp, 11-20ft-lb

The MK5 Supra Eventuri intake has been developed to provide the turbo with a less restrictive flow path whilst maintaining low inlet temperatures. Heat and Volume are the main considerations when designing an intake for turbocharged engines. In the Supra, the intake system is located next to the exhaust manifold which rapidly heat soaks the engine bay. High temperatures are detrimental for engine performance as the turbo would have to build boost with heated, less dense air and so the only way to ensure IAT’s are kept to a minimum is for a fully sealed intake. This however, results in a restriction with only one stock air feed to draw air in from. During development we noticed an additional opening into the wheel arch area and took advantage of this by adding a secondary feed to our airbox. Furthermore our sealed airbox also has a heat shield with gold reflective to minimize the radiative heat transfer from the exhaust manifold. In order to maximize volume we made the airbox as large as possible with a recess for potential strut braces. The stock convoluted intake tube is replaced with a smooth carbon tube which is also larger in internal volume with a starting internal diameter of 111mm (4.4″) smoothly tapering down to match the turbo inlet. The tube provides a smooth path from the filter to the turbo inlet. Finally we use a custom made high-flow dry filter which is ISO tested for filtration performance and has a larger filtration area than the stock filter.

A single comprehensive review of a single datalog.

Provide a professional opinion on how the calibration is running on your vehicle from a datalog.

Identify any shortcomings with the calibration, and any potential additions of hardware that may help support the calibration.

Identify reasons why your vehicle may be presenting symptoms you are concerned with.

While able to provide an opinion on what may be going on with your vehicle.  It is just that.  An opinion.  If there are hardware issues with the vehicle, it is in your best interest to have a professional ASE certified automotive technician, that you trust, assess what is wrong with the vehicle in person in order to rectify any potential hardware issues.

Upon submission of your datalog, please include the following.

1) Year, Make, and Model of your vehicle.
2) Any and all modifications that deviate from OEM specifications.
3) Any potential issues you may be having with the vehicle.  PLEASE BE AS SPECIFIC AS POSSIBLE.
