VIS Motorsport High Pressure Fuel Pump Upgrade Kit B9 EA839 – VISEA839V6

VIS Motorsport High Pressure Fuel Pump Upgrade Kit B9 EA839 – VISEA839V6 Upgrading B9 EA839 S4 / S5 / RS4 / RS5 / SQ5 and other engines with the same high-pressure fuel pump (HPFP) beyond their original power levels necessitates an increased volume of high-pressure fuel to prevent “fuel cuts”, particularly in the mid-range (3000-5000 rpm). In many instances, we observe a decline in pressure from the factory-installed fuel pump. The capacity of the high-pressure fuel pump to deliver fuel is contingent upon the volume displaced by the pressurising cylinder within the pump. To address this fuel shortage and ever-increasing power outputs, VIS Motorsport developed the 2.0T MQB HPFP Upgrade Kit to suit various build requirements. We are the first company to design and offer a larger stage/size kit that is both lighter than the original equipment manufacturer (OEM) by 2 grams and available to customers worldwide. The upgrade kit features a 25% larger surface area and can handle over 250 bar of pressure from the outset, culminating in over 50% more volume and weighing 10% less compared to the original equipment (fuel pressure depends on the specific engine type, as it fits numerous applications and engines). This high-performance kit is suitable for both big turbo applications and stock power. The piston head is optimised for ideal hydrodynamic flow, with a surface that has been hardened and heat-treated in two separate stages. The VIS Motorsport HPFP Upgrade Kit has been tested on a variety of configurations and hardware/software setups worldwide, consistently demonstrating its reliability and performance. *Includes fitting tool Technical Information Clearance at top of piston 0.0001-0.00015 Deviation of circularity max 0.001mm 370-450hb before rectification Nitrided at depth of 0.15-0.25 Hardness of hv10-760- kgf/mm2 for sleeve and hv 50-56/1200-1400kgf/mm2 for piston Nitrided H13 alloy/ 34mocr11 /rul 1vb3/ rul1vc2 Good thermal and shock resistance or heat cracking Mechanical characteristics and thoghness in hot condition,constant hardness throughout the production cycle High micro purity-level suitable for polishing Posibility to be coated to pvd/pa cvd methods flame induction hardening and nitriding Tensile strenght 1960kgf/mm2 Yeld strenght 1570kgf/mm2 Additional Information Weight 0.4 kg Dimensions 18 × 10 × 8 cm Brand VIS Motorsport
