VIS Motorsport HPFP Internals - 2.5TFSI RS3 (8P), RS3 (8V Pre-Facelfit) and TT RS (8J).
Modification of the 2.5T FSI EA855 and 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, VIS Motorsport developed the 2.5T FSI HPFP UPGRADE KIT to suits everybody's build needs. VIS Motorsport developed this upgrade kit to suits everybody's build needs.
It has 20% more surface area and is capable of OVER 150bar+ of pressure, ending with over 50% volume and UP TO 190bar+ and less weight by 10% compared to OE (Actual 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.
Tested on many configurations and different hardware/software setups around the globe.
