It pairs the cast stainless Gauntlet 1170-250 high pressure fuel pump kit, flowing 68% more than stock and 4% more than Nostrum's original Big Bore pump, with the Stage 2 direct injector set at 1434 cc\/min and 66% more flow than the factory injector. Together they take the 250 bar Gen 1 fuel system about as far as it goes, and both halves are ethanol compatible.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUpgraded-turbo B58 Gen 1 cars where a smaller injector set has already been outgrown\u003c\/li\u003e\n\u003cli\u003eFull E85 targets, where ethanol asks for far more volume than a petrol map\u003c\/li\u003e\n\u003cli\u003eFuel systems being specified once at the top of the Gen 1 range rather than stepped up twice\u003c\/li\u003e\n\u003cli\u003eTrack and high-duty use where rail pressure has to hold through repeated full-throttle pulls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow This Differs From The Stage 1 Bundle\u003c\/h2\u003e\u003cp\u003eThe pump is the same Gauntlet unit in both packages; the injectors separate them. Stage 2 carries 66% more flow against Stage 1's 35%, at the cost of a lower 220 bar injector rating, so the extra capacity is used as volume rather than pressure.
