VIS Motorsport HPFP Upgrade kit
EA839 HPFP KIT . Get the most out of your engine.
Modification of the EA839 engine B9 S4 / S5 / RS4 / RS5 / SQ5 &others sharing same hpfp engines far beyond OEM power levels requires an additional volume of high-pressure fuel in order to avoid "fuel cuts" especially in the midrange ( 3000-5000 rpm ).
In many cases we see the factory fuel pump begin to suffer from pressure loss.
The limitation of how much volume of fuel the high pressure pump can flow is dependent upon the volume displaced by the pressurizing cylinder inside the pump.
In order to address the lack of fuel ,and power outputs never stop increasing VIS Motorsport developed the EA839 HPFP UPGRADE KIT to suits everybody's build needs , we developed upgrade kit to suits everybody's build needs and the first company who designed and implement a working bigger kit/size available to customers around the world with
LIGHTER THAN OEM
It has 20% more surface area and is capable of OVER 275 bar+ of pressure, and less weight by 10% comparred to OE (fuel pressure is dependant to type of engine as it fits many applications)
This monster is ready for big turbo applications or just for stock power giving another 15 bar fuel rail pressure and some extra hp especially in mid range
Piston head is optimized for ideal hydrodynamic flow . The surface is hardened and heat treated in 2 different stages
It's being tested on many configurations and different hardware/software setups around the globe and have proven again and again the reliability and performance you can expect from each and every VIS Motorsport HPFP Upgrade kit.
