It pushes 38% more fuel flow out of the OEM high pressure fuel pumps by starting with genuine BMW vacuum pump cores and installing the Dorch Engineering cam inside the OEM assembly using Dorch's proprietary manufacturing tooling and validation equipment. The result is a large gain in fuel flow in a very simple, clean package that still uses the factory HPFPs.\u003c\/p\u003e\n\u003cp\u003eBecause the S55 engine uses some of the smallest fuel pump cams in the Bosch lineup, this additional flow is achieved without sacrificing any of the longevity or reliability of the OEM pumps. There is no cutting, no bending and no crimping; the kit drops straight in like factory and requires no special tuning to get up and running, with all of the safety and sophistication of the stock DME left in place. It is the only HPFP upgrade available that will successfully pass emissions on OEM DME mapping.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e38% more fuel flow from the OEM S55 high pressure fuel pumps\u003c\/li\u003e\n\u003cli\u003eBuilt on genuine BMW vacuum pump cores with the Dorch Engineering cam installed inside the OEM assembly\u003c\/li\u003e\n\u003cli\u003eFuel flow, HDP5 (stock S55): 1.527 cc per camshaft revolution\u003c\/li\u003e\n\u003cli\u003eFuel flow, HDP5 with Dorch Lift Kit: 2.100 cc per camshaft revolution\u003c\/li\u003e\n\u003cli\u003eFuel flow, Dorch Stage 1 HPFP with Lift Kit: 2.857 cc per camshaft revolution\u003c\/li\u003e\n\u003cli\u003eNo software changes required to run the upgrade\u003c\/li\u003e\n\u003cli\u003eRetains full OEM DME safety and control strategies\u003c\/li\u003e\n\u003cli\u003eThe only HPFP upgrade that will pass emissions on OEM DME mapping\u003c\/li\u003e\n\u003cli\u003eNo cutting, bending or crimping — drop-in factory fitment\u003c\/li\u003e\n\u003cli\u003eDorch lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDorch lifetime warranty\u003c\/li\u003e\n\u003cli\u003eDorch vacuum pump assembly\u003c\/li\u003e\n\u003cli\u003eVacuum pump sealing cap\u003c\/li\u003e\n\u003cli\u003eVacuum pump gasket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e Dorch specifies no software changes and no additional hardware to run this upgrade.\u003c\/li\u003e\n\u003cli\u003eHighly recommended: larger S63 EU5 injectors.
