This is Nostrum's 1050-250 pump kit for the Focus ST: a fully welded stainless assembly with 1.22 cc\/rev of geometric displacement, 36 percent more than standard. More supply at the rail lets a tuner bring boost in earlier and hold it, which shows up as a stronger midrange rather than a peak number, and it opens the door to E85 or a blend on a car that previously had to stay on 98.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMk3 Focus STs out of headroom on a stage-two style map.\u003c\/li\u003e\n\u003cli\u003eCars moving onto ethanol where the standard pump cannot keep the rail fed.\u003c\/li\u003e\n\u003cli\u003eDaily-driven STs chasing torque low down rather than a dyno headline.\u003c\/li\u003e\n\u003cli\u003eBuilds with a bigger turbo planned and the fuel side to sort first.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat Holds A Mk3 Focus ST Back\u003c\/h2\u003e\u003cp\u003eDirect injection pumps run off a camshaft lobe at half crank speed, so output is a function of size. The standard 2.0 EcoBoost unit is sized for a standard car; ask for more fuel mass per cycle and rail pressure falls, so the calibration has to pull timing or boost to stay safe. A larger pump matters most low and mid-range, where the injector has crank angle to spare and it is supply, not delivery, that is short.\u003c\/p\u003e\u003ch2\u003ePlanning The Rail Pressure Sensor\u003c\/h2\u003e\u003cp\u003eOn the standard rail sensor this pump is held to 190 bar. Nostrum's optional E460-1579 upgrade takes it to 250, and that is worth having because the same injector flows more fuel and sprays it better at higher pressure. Decide before the car goes in, because it changes what the tuner can command.

On 2013 and 2014 cars the calibration is still being validated, because current tuning tools cannot drive the pump solenoid on that ECU, so talk to us first. A tune is required, with COBB, HP Tuners and SCT supported and EMS, Dizzy Tuning, Stratified, Panda Motorworks and Tunewerks among Nostrum's tuners. The kit reuses the standard low-pressure feed line and is a direct bolt-on.
