It carries a larger diameter piston than the factory pump, giving 33% more displacement and a flow capacity of over 350 lph, in a stainless steel laser welded body that is flow and function tested so there are no leak paths through the high pressure side. On a pulleyed or heavily mapped supercharged V6 the standard pump is what starts to run thin as rail demand climbs, particularly on ethanol, and this is the part that removes that limit. It is a single pump supplied with OEM fittings and the hardware, electrical connectors and accessories needed to fit it.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSupercharged S4 and S5 builds on a smaller pulley where rail demand has climbed\u003c\/li\u003e\n\u003cli\u003eFlex fuel and ethanol running on the 3.0 TFSI, which asks far more of the pump than petrol\u003c\/li\u003e\n\u003cli\u003eSQ5, Q5, A6 and A7 owners upgrading the fuel side before chasing more elsewhere\u003c\/li\u003e\n\u003cli\u003eCars being built to a plan, where the pump is chosen once for the finished spec\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere The Standard Supercharged V6 Pump Runs Thin\u003c\/h2\u003e\u003cp\u003eFuelling on this engine is deceptive. It pulls hard from low revs, so the pump spends a long time near its limit rather than briefly touching it at the top of a pull. More displacement per revolution means the pump is not fighting to keep up in the mid-range, which is exactly where a supercharged V6 does its work.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: high pressure fuel pump (HPFP), single pump\u003c\/li\u003e\n\u003cli\u003eSKU: H136-0897\u003c\/li\u003e\n\u003cli\u003eVehicle Application: Audi 3.0 TFSI supercharged V6, EA837\u003c\/li\u003e\n\u003cli\u003eFlow: over 350 lph\u003c\/li\u003e\n\u003cli\u003eDisplacement: 33% more than stock\u003c\/li\u003e\n\u003cli\u003eConstruction: stainless steel laser welded, CFD optimised\u003c\/li\u003e\n\u003cli\u003eFuel compatibility: flex fuel compatible\u003c\/li\u003e\n\u003cli\u003eIncluded items: pump with OEM fittings, hardware, electrical connectors and accessories\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eEA837 Or EA837 EVO\u003c\/h2\u003e\u003cp\u003eThis pump is for the earlier CAJA and CCAA supercharged V6.
