{"product":{"id":11142676808022,"title":"Nostrum 800cc Universal PFI Injector, Single Cone Spray, USCar, Each","body_html":"\u003ch2\u003eSummary\u003c\/h2\u003e\u003cp\u003eThe Nostrum 800cc universal port fuel injector is the larger of Nostrum's two single-cone USCar injectors, and the one to specify when a high ethanol blend or a bigger port setup would leave the 640 running near the top of its duty. It keeps the same cone spray that suits a normal inlet port and the same USCar plug most aftermarket looms are built for, so moving up the range is a flow decision rather than a re-plumb and a rewire. Each listing covers one injector, so you can buy per cylinder, buy a spare, or replace a single failure.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEthanol-blend port builds, where the same target needs noticeably more fuel volume than pump petrol\u003c\/li\u003e\n\u003cli\u003eLarger capacity engines where per-cylinder demand outgrows a 640cc injector\u003c\/li\u003e\n\u003cli\u003eAdded port fuel on direct injection engines already at the limit of their standard injectors\u003c\/li\u003e\n\u003cli\u003eWorkshops keeping one flow rate on the shelf across several customer builds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eChoosing Between The 640cc And The 800cc\u003c\/h2\u003e\u003cp\u003eBigger is not automatically better. A larger injector gives you headroom at full load but shortens pulse width at idle and cruise, which is where metering gets harder. On pump petrol with modest per-cylinder demand, the \u003ca href=\"\/products\/nostrum-640cc-universal-pfi-injector\"\u003e640cc injector\u003c\/a\u003e is usually the tidier choice. Once ethanol content climbs or capacity grows, the extra 160 cc\/min here stops being spare capacity and starts being the reason the setup works at all.\u003c\/p\u003e\u003ch2\u003eWhat The Single Cone Spray Suits\u003c\/h2\u003e\u003cp\u003eA cone spreads fuel out as it leaves the tip rather than sending it as one narrow stream, which suits a conventional inlet port with a reasonable run to the valve. Where the injector sits very close to the valve or fires down a short straight tract, a pencil stream injector from the same range is the better match.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: universal port fuel injector\u003c\/li\u003e\n\u003cli\u003eSKU: W065-0872\u003c\/li\u003e\n\u003cli\u003eFlow rate: 800 cc\/min\u003c\/li\u003e\n\u003cli\u003eSpray pattern: single cone\u003c\/li\u003e\n\u003cli\u003eConnector: USCar\u003c\/li\u003e\n\u003cli\u003eIncluded: one injector, sold individually\u003c\/li\u003e\n\u003cli\u003eFitment type: chosen by flow, connector, body dimensions and spray pattern rather than by vehicle\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConfirm overall length and both o-ring sizes against your rail and manifold before ordering.\u003c\/li\u003e\n\u003cli\u003eYour loom needs USCar plugs, or an adapter harness sourced separately.\u003c\/li\u003e\n\u003cli\u003eFlow and dead time data must be loaded into the calibration and the fuelling re-checked before the engine is driven.\u003c\/li\u003e\n\u003cli\u003eThese are supplied one at a time, so multiply by your cylinder count when you order.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eNostrum High Performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eUniversal port fuel injector (PFI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003eW065-0872\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFlow Rate\u003c\/th\u003e\n\u003ctd\u003e800 cc\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpray Pattern\u003c\/th\u003e\n\u003ctd\u003eSingle cone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnector\u003c\/th\u003e\n\u003ctd\u003eUSCar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSold As\u003c\/th\u003e\n\u003ctd\u003eSingle injector (each)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment Type\u003c\/th\u003e\n\u003ctd\u003eUniversal - matched by flow, connector, dimensions and spray\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eIs 800cc enough for an ethanol build?\u003c\/h3\u003e\u003cp\u003eIt depends on how much fuel each cylinder has to pass, not on the headline flow number.
