{"product":{"id":11142674153814,"title":"Nostrum Ford Mustang 2.3 EcoBoost Standard Bore Plus HPFP Kit","body_html":"\u003ch2\u003eSummary\u003c\/h2\u003e\u003cp\u003eThe Nostrum Standard Bore Plus kit replaces the camshaft-driven high pressure fuel pump on the 2015-2023 Ford Mustang 2.3 EcoBoost, and on a modified car that pump is usually what decides where the tune has to stop. More boost, a sharper calibration or a move to ethanol all ask for fuel the factory unit cannot deliver, so the tuner backs off to stay safe. This laser-welded stainless pump flows 37% more fuel than the factory pump and works to 240 bar, and it comes with the application-specific high pressure tube, low pressure line, mounting flange and installation tool. It is the middle pump in Nostrum's Mustang range: more flow and rail pressure than the plain standard bore pump, less outlay than Big Bore, and enough for pump E85 on a stock-turbo car.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStock-turbo 2.3 EcoBoost Mustangs meeting a fuelling limit before the calibration is finished\u003c\/li\u003e\n\u003cli\u003eCars moving onto pump E85 or an ethanol blend, where fuel demand climbs well above petrol\u003c\/li\u003e\n\u003cli\u003eOwners who want headroom now without paying for Big Bore capacity they will not use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere The Stock Pump Runs Out\u003c\/h2\u003e\u003cp\u003eA direct injection fuel system runs out in two places. The pump caps the mid-range where peak torque lives; the injectors cap the top end, where there is less crank angle available to inject. The HPFP is driven off the camshaft at half crank speed, so extra displacement pays off lowest down, exactly where a tuner wants boost in earlier. The 240 bar ceiling helps too: the same injector moves more fuel at the same pulse width.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: direct injection high pressure fuel pump kit\u003c\/li\u003e\n\u003cli\u003eSKU: H086-1516\u003c\/li\u003e\n\u003cli\u003eVehicle Application: 2015-2023 Ford Mustang 2.3 EcoBoost\u003c\/li\u003e\n\u003cli\u003eFlow: 37% more than the factory pump\u003c\/li\u003e\n\u003cli\u003eGeometric displacement: 1.524 cc\/rev\u003c\/li\u003e\n\u003cli\u003eMax operating pressure: 240 bar \/ 24 MPa \/ 3500 psi\u003c\/li\u003e\n\u003cli\u003eFuel: E85 compatible\u003c\/li\u003e\n\u003cli\u003eIncluded Items: welded stainless HPFP, flange, low pressure fuel line, high pressure fuel tube, flange installation tool, install guide\u003c\/li\u003e\n\u003cli\u003eRequired: a supporting calibration, which is not included\u003c\/li\u003e\n\u003cli\u003eFitment type: vehicle-specific, built as a direct bolt-on kit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eStandard Bore Plus Or Big Bore\u003c\/h2\u003e\u003cp\u003eBoth Mustang pumps run to 240 bar, so the question is how much capacity the build will ask for.
