  2. 550CC MULTI HOLE BOSCH FUEL INJECTORS, SET OF 5

 

Below is a more detailed description of all the components included in the TXX Turbo package.

Dreamscience DS TXX K16 Hybrid Turbo upgrade – Dreamscience have worked closely with AET-Turbos over the last 3 months to co-develop a New generation of Hybrid Turbo upgrade for the Focus ST225 which develops great performance, reliability and value for money. We have incorporated a Forge actuator and Forge Motorsport re-circulating dump valve to this turbo unit and have increased the size of the compressor wheel and machined out the Housings to accept the new Turbine and Compressor wheels in addition, the entire unit has been ported and polished to increase the overall efficiency of the unit. After intensive testing and many specification changes we have now signed off the DS TXX k16 unit for production as below.

 

Bosch 550cc multi hole injectors x 5 – . These injectors are used as part of our stage 4 kit as from testing the standard injectors start to become inefficient at around 326Bhp +/- depending on temperature, commanded lambda, barometric pressure etc. These new 550cc injectors are a must recommended  for the new TXX. In all cases any injector bigger than 550cc will not run correctly and are unnecessary leading to ecu recalibration. At 380 real Bhp we still hold 11.5:1 AFR with the 550cc injector so any bigger is unnecessary and will not run as well.

TXX ECU remap – The TXX map has been developed to offer maximum performance while maintaining reliability and efficiency, as described by Performance Ford, “It’s designed to perform and feel as if it’s original factory fitment”. To use the TXX map it is mandatory to have 550cc injectors, an uprated oil cooler, and the DS TXX Turbo upgrade, we have not tested this on any other variant and have no plans to. The TXX map power delivery is designed to keep climbing as you go through the rev range, there is no massive lump in the low to mid range followed by the disappointment of losing all your power and boost. This map holds above 300Ftlb from 2000 rpm to just above 6500 rpm and has a very progressive / flat torque curve. As can be seen by the dyno graph TXX is controlled at low rpm to help a sensible torque figure which ensures the drive train is kept safe and in tact and as the rpm climbs all hell breaks loose. The biggest challenge when writing the new map over the last 12 months was to keep things sensible yet powerful. By using the 550cc injectors we are able to slightly over fuel the car to a steady commanded lambda of 11.5 to 1, this helps keep the cylinders cooler and also allows us to use more advanced ignition tables.

 

Customers who buy this package via mail order have two options;

  1. We can email the File to your Stratagem iMap/Ultra handset.
  2. WE CAN LOAD THE TXX TUNE ONTO A BLANK IMAP TUNING HANDSET SO YOU CAN UPLOAD THE FILE YOURSELF.

Customers who do not have a tuning product already and wish to buy an Imap with the TXX map pre-loaded can do so by selecting it from the options.

What mods are recommended to run this package?

  • FULL CAIS
  • STAGE 3 OR 4 INTERCOOLER SET UP
  • FULL 3″ EXHAUST SYSTEM
  • RS OIL COOLER (MUST HAVE)
  • 340LPH FUEL PUMP UNIT (HIGHLY RECOMMENDED)
  • BLOCK MOD
  • UPGRADED CLUTCH

If you do not have any of the above, you can add in the drop down sections if required.

Optional Upgrades:

340lph Fuel pump unit. including RS Sender unit.
With this kit making so much power and the turbo is flowing so much air, we highly recommend adding this fuel pump to your package. The standard fuel pumps with old age can struggle to provide the fuel as efficiently as we’d like. 

We have an off the shelf answer to fuelling your high powered Focus RS/XR5 Mk2, this fuel pump upgrade is a straight swap for your standard pump unit and utilises a 340-litres per hour fuel pump!
