Why Aux Fuel?

Direct injected cars offer an increased level of efficiency and capabilities. However, the fuel systems are very expensive and difficult to upgrade when we want to extract more power from the engine. On top of this they have issues such as intake valves that get dirty. So it was time to innovate and allow you guys to enjoy a more powerful and safe Ecoboost!

Recommended for up to 450 WHP on the Focus ST. Check out our 4-port kit if you want more power!
Protects your engine from fuel starvation on Big Turbo setups
Provides the extra fuel needed for more boost and power
Keeps intake valves clean to avoid low speed pre-ignition (a form of super knock)
Directional injection that ensures even distribution of  fuel
Better fuel metering and atomization than a WMI system
Water-methanol injection (WMI) port included for non-E85 users
Fully Plug and Play. No cutting, splicing, soldering or any non-reversible modifications
No extra tanks or reservoirs or pressure regulators needed
E85 Safe

The OEM DI (direct injection) fuel system in the 2.0 EcoBoost can deliver fuel for up to around 375 WHP, but after this point it starts to run out in two main areas: The HPFP (high pressure fuel pump), and fuel injectors. The HPFP is the first to lose pressure and this can cause driveability issues such as sputtering or not running smooth to redline. The DI injectors are soon to follow in terms of flow limitation especially if fuel pressure drops. This can put the motor at risk of running lean and is especially dangerous when running a bigger turbo! Upgrades for these components however, are both expensive and in the case of the HPFP simply not available.

Auxiliary fuel can provide that extra volume of fuel to relieve some of the load that high horsepower builds demand from the OEM fuel system. It also helps run a richer mixture which keeps detonation and heat down which are the major factors that contribute to piston and engine failure. 

Additionally, aux fuel has much better fuel metering and atomization than a WMI system - it is a proper fuel system that is also more reliable.

Direct injected cars offer an increased level of efficiency and capabilities. However, the fuel systems are very expensive and difficult to upgrade when you want to extract more power from the engine. Many OEMs opt to run both port and direct injection systems on their high power vehicles. This way you keep the DI system's efficiency and only use the port aux system at wide open throttle.

Below is an image that is all too common of fuel pressure drops even when the 2.0 EcoBoost is making around 360whp without auxiliary fueling.




The Stratified Xtra Fuel System addresses both the HPFP and injector shortcomings with a single, plug and play auxiliary fuel system. Without any other upgrades there is enough fuel available for 450 WHP even with the OEM in-tank fuel pump. Below you will see how fuel pressure stays up with the aux system above 25psi of boost with a GTX2867 turbo.

Once installed, the system should be tuned (tuning is needed!) to work in tandem with the OEM fuel delivery system for seamless and safe power delivery - especially when using ethanol based fuels that have higher fuel flow requirements. 

The controller is programmed using a serial/DB9 port. If you don't have a USB converter cable already make sure you purchase that option.
