From LOBA's site.....

We take a brand new factory OEM pump for reliability, then we make fundamental changes using new components and processes by LOBA to create this upgrade fueling solution. Also Included with this upgrade are OEM Cam follower and OEM Pump O-ring seal.

Modification and tuning of the 2.0TFSI engine way beyond OEM power levels requires an extra volume of high-pressure fuel. The LOBA 2.0 TFSI high pressure fuel pump will give a fuel volume increase of more than 50% and can sustain over 135bar making it the one of the biggest flowing pumps on the market. Also suitable on a stock software car.
The LOBA uprated fuel pump allows much more power throughout the rev range but specifically in the midrange on cars where the stock pump is insufficient.

The materials and processes we decided upon are of the highest possible quality and for this particular application, this meets the very high requirements needed for the latest generation of OEM HPFP specifications. Multiple stages of various precision machining, hardening processes, coating processes and quality control inspections characterize this LOBA pump.

Tested to over 8250rpm both in a controlled environment and on the track/road to simulate a large range of dynamic conditions. Doing so was an important part of our mechanical design parameters to ensure the LOBA pump meets our standard. Results are reliability, durability and performance.
